Batch Processing Of Non-standard Parts: Realizing Personalized Customized Mass Production

Batch processing of non-standard parts: realizing personalized customized mass production

What is batch processing of non-standard parts?

In the manufacturing industry, many parts are not standard parts and must be customized according to the specific needs of customers. This is the origin of non-standard parts. In the past, such parts could only be produced in single pieces or in small batches, which was costly and took a long time.

Nowadays, with the widespread application of CNC technology and flexible manufacturing systems, batch processing of non-standard parts has become a reality. Enterprises can achieve large-scale production while ensuring that personalized needs are met, and efficiency is greatly improved.

Why choose non-standard parts

Products in the market are increasingly pursuing differentiation. Standard parts are often difficult to meet special design and fonction requirements. Some equipment must adapt to specific working environments, and some parts need to bear special functions.

The processing services of personalized customized parts have become popular. From the automotive field to the medical device field, from aerospace to consumer electronics, there is a demand for customized non-standard parts in various industries. This is an important manifestation of corporate competitiveness.

Advanced technology supports mass production

CNC machining centers are used as mainstream equipment for mass manufacturing of non-standard parts. Through programming control, one machine tool can continuously process a variety of different parts and flexibly respond to different orders.

Another great tool is the flexible manufacturing unit. It can change the processing program by itself to achieve mixed line manufacturing of multiple varieties and small and medium-sized batches. It not only retains the advantages of customization, but also obtains the economy of mass production.

Batch processing effectively reduces costs

The traditional concept is that customization is equivalent to high cost, but this is not the case. When non-standard parts can be mass-produced, the unit cost will be significantly reduced, the material utilization rate will be improved , personalized customized parts processing services will be provided, the line change time will be reduced, and the labor cost will also be diluted.

More importantly, large-scale production makes it easier to standardize quality inspections. Companies can build complete quality control processes to customize parts processing services to ensure that each batch of parts meets customer standards, thereby reducing rework and waste.

Improve enterprise market response speed

For enterprises, being able to quickly transform design drawings into mass-produced products is the key to their advantage in market competition. The batch processing of non-standard parts allows companies to shorten the time cycle from research and development to mass production, thereby being able to respond to customer needs in a timely manner.

This kind of agility is particularly important in an industry with extremely fierce competition. While your competitors are still worrying about single-piece customization, your products have already been delivered in batches and are on the market. Non-standard parts are batch processed: mass production of personalized customization is achieved. In this way, market opportunities will naturally be seized by you.

How to break through in the face of challenges

Batch processing of non-standard parts, which is a personalized customized parts processing service for enterprises, requires very high technology, and it also needs to continuously invest funds to update equipment. At the same time, this is also a test for process research and development capabilities, and companies must continuously optimize processing plans and fixture designs.

The establishment of a quality management system is of equal importance. From the inspection of raw materials to the inspection of finished products, every link must be strictly controlled to ensure that every non-standard part in the mass production process can achieve customer satisfaction.

The demand for diverse precision parts has become increasingly prominent in modern manufacturing. Traditional mass production methods are difficult to meet the requirements of special specifications. CNC high-precision customization services are the key solution to fill this gap and are the key response to this situation.

Rigorous process from drawings to finished products

The first step in custom processing is for the customer to provide detailed design drawings that clearly indicate dimensional tolerances, surface roughness and material requirements. This step determines the direction of all subsequent processes, and any deviation will be magnified on the finished product. This step determines the direction of all subsequent processes, and any deviations will be amplified in the finished product.

After receiving the requirements, engineers will use CAD/CAM software to carry out process analysis and programming work, and convert the design into G code instructions that can be recognized by the machine tool. This process requires profound technical accumulation to ensure accuracy.

Machine tool accuracy determines finished product quality

The motion accuracy of CNC machine tools will have a direct impact on the processing quality, and its repeated positioning accuracy will also have a direct impact on the processing quality. Those high-end equipment can achieve micron-level processing effects, and even sub-micron-level processing effects, which can fully meet the requirements of precision parts.

The program controls the precise motion trajectory of the tool, and cutting operations, drilling operations, milling operations, etc. are carried out in one go. Under the precise control of CNC machine tools, raw materials are gradually formed into finished parts that meet the design requirements.

Strict requirements for precision in medical equipment

Implants in medical devices, as well as surgical instrument parts, etc., have particularly complex shapes and extremely high precision requirements. Conventional processing methods cannot satisfy them at all, so CNC customization has become the only reliable option.

Starting from artificial joints to dental implants, each batch must be individually customized according to the specific needs of doctors and patients, and dimensional errors must be controlled within a very small range to ensure safety and functionality in the human body.

Challenges of tiny parts in the electronics industry

Connectors, heat sinks, sensor housings and other parts in electronic components are small in size, but their precision requirements are high. CNC machining can achieve complete molding of complex structures.

Are There Any Requirements For Sheet Metal Processing Tolerances?

Are there any requirements for sheet metal processing tolerances?

Basic concepts of tolerance

When sheet metal is processed, the dimensions cannot be completely accurate. There are limitations in the accuracy of mechanical equipment. There are also many factors such as wear and tear of the mold, and errors in operation. These will affect the quality of the finished product. In order to ensure that the workpiece can be put into normal use, the tolerance must be controlled within a reasonable range.

Tolerance refers to the range within which variations in dimensions are allowed. The concept of basic size is the target value determined during design, while limit size is the maximum and minimum allowable boundaries. The difference between the two boundary values is the size of the tolerance zone.

How to read the tolerance code

The national standard clearly stipulates the tolerance codes of holes and shafts. For holes, the upper deviation is represented by ES, and the lower deviation is represented by EI. As for the shaft, the upper deviation is expressed by es, and the lower deviation is expressed by ei. Only by understanding these codes can we accurately determine whether the part is qualified.

Deviation can be defined as positive, negative, or zero. The upper deviation is the algebraic difference obtained by subtracting the basic size from the maximum limit size. The lower deviation is the corresponding result obtained by subtracting the basic size from the minimum limit size. Marking the fit tolerances can make processing and inspection more convenient.

How to design a bending mold

The rebound of special sheet metal during bending is larger than that of ordinary materials. It is difficult for ordinary molds to meet the accuracy requirements. The company has specially developed a replaceable roller structure lower mold. The R corner part is made of LD material, which can roll during the bending process, which can effectively reduce surface indentations.

Generally speaking, the R angle of the upper mold is selected to be three to six times the material thickness, the R angle of the lower mold is selected to be four to eight times the material thickness, and the V opening width is selected to be six to twelve times the material thickness. Such a combination of parameters can effectively control the bending rebound phenomenon and prevent cracking. At the same time, it can also avoid leaving indentations on the outer surface.

What should you pay attention to when bending

Set the bending direction to ensure that it is always perpendicular to the direction in which the plate is rolled, thus reducing the risk of cracking. Before starting the bending operation, all defects on the surface of the plate need to be polished until they are clean, smooth and without traces. The edge formed after shearing must also be polished to a smooth level to prevent deformation caused by stress concentration.

Once the strength of the plate is higher, the bending force and the amount of rebound will be greater. Materials with high hardness require greater bending force and more obvious rebound. Therefore, when designing mold parameters, the mechanical properties of the material must be fully considered.

Advantages of removable structures

Based on cost and maintenance considerations, the R-angle of the upper mold, the R-angle of the lower mold, and the mold body are all designed to be removable. After wear occurs in a certain part, only partial parts need to be replaced instead of scrapping the whole thing. This greatly reduces the cost incurred in the long-term use.

This flexible production method that facilitates product upgrades and adjustments can meet the precision requirements of the welding process. The initial investment is relatively small, the investment return period is short, and the requirements for equipment and operators are also low, making it suitable for small and medium-sized enterprises.

Features of water jet cutting

Waterjet cutting is suitable for the blanking process of all special sheet metal products. The biggest advantage of this process is that it has no heat-affected zone and can completely avoid the risk of cracks caused by thermal deformation. The quality of the cuts is stable.

Compared with laser cutting and plasma cutting, waterjet has more advantages for thick plates and high-strength materials. Its cold cutting characteristics ensure that the internal structure of the material will not be destroyed, and the quality of subsequent bending and welding is more guaranteed.

During actual production, have you ever encountered a situation where bending springback is difficult to control? Welcome to share your experience and solutions in the comment area.

Paint And Coating Anti-corrosion Testing Standards, Testing Items And Testing Scope

Paint and coating anti-corrosion testing standards, testing items and testing scope

1. The importance of anti-corrosion coating testing

Many construction teams are not familiar with the testing process of anti-corrosion coatings, resulting in uneven coating quality. Some projects may appear to be fine on the surface, but rust and peel off after being put into use, causing unnecessary economic losses to the company. Understanding paint testing items is the first step to ensure project quality.

Testing is not just for acceptance, but also to prevent problems. By carrying out experimental tests on physical properties, construction properties, chemical properties and other dimensions, we can discover possible hidden dangers in the coating in advance, so as to ensure that the anti-corrosion coating will exert the protective effect it should have when it is actually put into use.

2. Physical performance testing items

The most basic testing content of coatings is physical properties. The appearance inspection needs to check whether the color and transparency meet the requirements. The adhesion test needs to determine whether the coating can be firmly bonded to the surface of the substrate. The viscosity and fineness will have a direct impact on the construction effect. Indicators such as ash content, PH value, and flash point are also within the scope of testing.

Volumetric solids content, as well as density, determine the practicality of the coating, as well as cost accounting. Bonding strength is a key parameter that measures the ability of the coating to bond with the substrate. These indicators are directly related to the actual performance after painting, and each item must be strictly controlled.

3. Construction performance testing items

On-site operation efficiency and final film quality will be affected by construction performance. The hiding power test is used to evaluate the covering effect of the coating. However, due to various unknown factors, usage and loss are related to cost control. Drying time is a key reference for construction arrangements . Film thickness detection standards for riveted weldment spray paint, paint and coating anti-corrosion testing standards, testing items and testing ranges, surface drying time and actual drying time must be accurately recorded.

The beauty of the painted surface is determined by the paint film's polishability, leveling and sagging properties. The measurement of wet film thickness and dry film thickness is the core link in construction acceptance. A reasonable film thickness can ensure the anti-corrosion effect without causing material waste.

4. Chemical performance testing items

The coating's ability to withstand complex environments is reflected by its chemical properties. This test content of water resistance can simulate its performance in a humid environment. Durability assessment focuses on the long-term effects of a coating's use. Alkali resistance and corrosion resistance are assessed based on special working conditions in professional fields such as chemical industry and specific environments such as the ocean.

Through weather resistance testing, we can observe the stability of the coating under ultraviolet rays and temperature changes. Heat resistance and low temperature experiments are used to test the adaptability of the coating in extreme temperature environments. Chemical resistance can ensure that the coating is not easily damaged when it comes into contact with acid and alkali solvents.

5. Hazardous Substance Testing Projects

As the requirements for environmental protection become more and more stringent, the detection of harmful substances is absolutely indispensable. VOC content is a key category of data indicators that need to be paid attention to. The total amount of A, B, and 2A must be controlled within a safe range. The content of free formaldehyde will directly affect indoor air quality.

What is related to the health of construction workers is the sum of the TDI and HDI contents. The detection of ethylene glycol ether is to prevent harm caused by solvent residues. The heavy metal content (lead, mercury, chromium, cadmium, etc.) must be within the limited standards. Not only do these indicators affect environmental compliance, but they are also related to human health.

6. Electrical performance testing items

For special-purpose anti-corrosion coatings, it is necessary to have relevant testing of electrical properties. The conductivity test is used to evaluate the application value of the coating in electrostatic protection or cathodic protection. As for breakdown voltage or breakdown strength, they reflect the insulation properties of the coating.

The insulation resistance and dielectric constant are used to evaluate protective coatings for electronic equipment. The dielectric loss tangent is related to the application effect in high-frequency environments. These indicators are of irreplaceable importance in specific industries.

A variety of coating types are covered by testing standards, including types from chlorinated rubber to epoxy asphalt, and types from phenolic anti-rust paint to perchlorethylene anti-corrosion paint, each of which has corresponding specifications. The test methods include the circle method, the cross-hatch method, and the pull-apart method to determine the adhesion , film thickness detection standards for riveted weldment spray paint , and two film thickness detection methods, destructive and non-destructive.

What paint testing challenges have you encountered at work? Welcome to leave a message for discussion!

Bridge Construction Always Overturns? The Advantages And Disadvantages Of 3 Types Of Bridge Formwork Are Explained Clearly, So There Are No Pitfalls When Selecting Materials.

Bridge construction always overturns? The advantages and disadvantages of 3 types of bridge formwork are explained clearly, so there are no pitfalls when selecting materials.

The cause of bridge pouring problems has been found

Concrete with pitted surfaces, concrete with leaking joints, and concrete with deformed components. The first reaction of many construction workers is that the pouring process is defective. In fact, after detailed investigation of the technical specifications for riveting and welding of Q345 steel plates for bridges , it can be found that the root cause is often in the formwork. Since the formwork is a direct load-bearing object formed by concrete, inappropriate selection of materials or irregular use are the driving force behind the emergence of various common quality problems.

In engineering practice, the same type of problems will appear repeatedly in many projects, and rectifications are carried out repeatedly, but only the symptoms are treated but not the root cause. If the formwork itself lacks rigidity, the joints are not tight, or the release agent is not applied properly, problems will inevitably occur after the concrete is poured. Selecting the right formwork and standardizing the construction are the first steps to ensure the quality of bridge components.

The role of formwork in bridge engineering

The bridge formwork, which is responsible for the two important tasks of forming and load-bearing, has the primary function of shaping. It must be accurately formed according to the construction drawings to ensure that the piers, cap beams, box beams and other components have good dimensions and neat lines. This will have a direct impact on the appearance quality and structural safety of the bridge.

At the same time, the formwork needs to withstand the lateral pressure of the concrete and the vibration impact force. If the stiffness is insufficient or the reinforcement is not strong, serious quality problems such as mold running, mold expansion, deformation, etc. may occur, and even safety accidents may occur. A good-quality formwork system can achieve standard molding in one go, reducing the workload of subsequent repairs.

Analysis of the advantages of Q345 steel formwork

Q345 steel plate is one of the most widely used formwork materials in current bridge projects. This steel has high strength, good toughness, and outstanding welding performance. It can meet the stringent requirements for formwork stiffness and stability of bridge components. The steel formwork made of national standard Q345B steel has tight seams and can effectively prevent slurry leakage.

Formwork made of Q345 steel plates through riveting and welding can be turned over 50 to more than 100 times. Under normal use conditions, the concrete surface is smooth and smooth, and secondary repairs are basically not required. For high-standard projects such as high-speed rail, cross-sea bridges, and highways, shaped steel formwork is the best choice for the construction of core components of bridges.

Limitations of other template materials

Traditional wooden formwork is relatively cheap and can be cut at will. However, it has poor stiffness and is prone to deformation when exposed to water. Its turnover times are only three to five times. Problems occur frequently during construction on rainy days. The concrete surface is prone to defects. This type of formwork is only suitable for small bridges or temporary projects.

The plastic formwork itself is light in weight, has waterproof and moisture-proof properties, and is easy to demould. However, its rigidity and bearing capacity are significantly less than the technical specifications for riveting and welding of Q345 steel plates for bridges . It is only suitable for low-load small components such as bridge guardrails and simple caps. It definitely cannot be used in key load-bearing parts such as high bridge piers and long-span box girders. Blind selection will bury quality risks.

Riveting and acceptance technical requirements

Templates should be made in strict accordance with the specifications and standards. The steel plates selected are mainly Q345B bridge riveting technical specifications for Q345 steel plates . The welds are full and uniform, and the riveting is firm and there is no looseness. After the assembly is completed, the board surface should remain flat and free of rust, the seams should be tight and there should be no obvious misalignment, and the overall geometric size error should be controlled within the allowable range.

Before construction, the board surface must be cleaned and the release agent evenly applied. During installation, the verticality and joint quality must be strictly controlled. The reinforcement support system must be in place. After the formwork is removed, it must be cleaned and maintained in time. The steel formwork must be rust-proofed. This can effectively extend the turnover service life and reduce the overall cost.

How to scientifically choose template solutions

There is no material selection suitable for any place in construction. Large-scale bridge projects with high standards should first use Q345 steel formwork to ensure structural quality and construction progress; for small temporary projects or special-shaped component construction, traditional wooden formwork can be considered to reduce costs; simple low-load scenarios can use plastic formwork.

Selecting materials and cooperating with standardized construction operations can avoid most common problems in bridge construction quality. If the formwork is properly selected and the construction process follows specifications, problems such as pitted surfaces, grout leakage, and deformation will naturally be reduced.

Riveters Exposed To Occupational Hazards

Riveters exposed to occupational hazards

Noise and vibration harm the body

Riveting operations are inseparable from the riveting guns and air compressors used for the operation. These equipments produce extremely high levels of noise during operation. If you work in this environment for a long time, your hearing will slowly decrease. In severe cases, you may suffer from occupational noise deafness.

Workers' arms will be injured by vibrations from tools. When using rivet guns and pneumatic tools, the vibrations will be transmitted along the arms to the wrists and elbow joints. Over time, the fingers will become numb and painful, and the muscles will become weak.

Radiation hazards and hidden risks

When working with a rivet gun, electromagnetic radiation will be produced. If it is exposed to it for a long time, it may have an impact on the nervous system and immune system. Although it is not as obvious as other hazards, this potential impact is worthy of attention.

If you are doing welding work, the ultraviolet rays in the arc light will be more dangerous. It can cause eye burns, thereby causing electro-optical ophthalmia, and can also make the skin red and blistered. Therefore, it is very important to protect your eyes and skin.

Smoke and dust poisonous gas are most harmful to the lungs

During welding operations, high temperatures will expose the welding rods and metal to melted riveters, exposing riveters to occupational hazards, thereby producing a large amount of smoke. These smokes contain harmful substances such as iron oxide, manganese oxide, and silicon dioxide. When workers inhale them, they are prone to metal fume fever, causing symptoms such as fever, chills, and fatigue.

The nitrogen and oxygen in the air affected by the welding arc will react, thereby generating carbon monoxide and nitrogen oxides. Carbon monoxide will cause hypoxia in the human body, and nitrogen oxides will irritate the respiratory tract, and in severe cases can cause pulmonary edema.

Dust accumulation causes disease

When grinding metal surfaces, a large amount of dust will be generated. When nails are processed, a large amount of dust will also be generated. These dust particles are extremely small and float in the air. Workers can easily inhale them. In the long run, the accumulation of these dust in the lungs can cause pneumoconiosis or chronic obstructive pulmonary disease.

Workers suffering from this disease often cough and have shortness of breath, and their breathing becomes increasingly difficult. Some people only notice the problem after they retire, when lung damage is already extremely difficult to recover from. Precaution is more important than subsequent treatment.

Protective measures must be in place

In order to reduce noise transmission and environmental protection and labor protection measures during metal riveting and welding processing , companies should install noise reduction equipment and be equipped with local exhaust devices to remove smoke and dust in a timely manner. These engineering control measures can reduce hazards from the source.

Workers must wear masks to prevent dust from entering the respiratory tract, ear defenders to protect ears, and glasses to protect eyes. Personal protective equipment is the final line of defense and must not be ignored just to save trouble. It is also important to conduct regular inspections and replace protective equipment.

Physical examination and monitoring are essential

Riveters are required to undergo regular occupational health examinations. Hearing tests can detect early hearing damage. Pulmonary function tests can assess the condition of the respiratory system. Once a problem is discovered, intervention measures should be taken as early as possible to prevent the condition from getting worse.

Enterprises need to optimize their work processes to reduce workers' exposure to multiple hazards at the same time as much as possible. For example, make reasonable arrangements for the sequence of welding and grinding, and give workers adequate rest time. Only through the coordinated efforts of multiple parties and measures can we effectively protect the health of workers.

What kind of occupational disease prevention measures does your unit have and how effective are they? You are welcome to share your experience in the comment area.

Stainless Steel Drawing Stamping Parts Processing, Small Hardware Processing, Hardware Accessories Stamping Processing

Stainless steel drawing stamping parts processing, small hardware processing, hardware accessories stamping processing

As the basic process that allows the manufacturing industry to exist, stamping parts processing, unexpectedly, many factories frequently make mistakes in the material selection and design process. Today, the six key points of the stamping process will be explained thoroughly to help you effectively reduce detours and effectively reduce costs.

Core principles of stamping process

The press and the mold will exert external force on the plate, which can cause plastic deformation or separation of the material. In this way, parts of the required shape can be obtained. This process is stamping. It is a plastic processing like forging and is collectively called forging.

More than half of global steel products are made of plates, most of which are stamped into finished products. Automobile bodies are stamped parts, radiator fins are stamped parts, and electrical appliance cores are also stamped parts. Their application range is very wide.

Wide range of applications for stamping parts

The largest user of stamping parts is automobile manufacturing. Body panels are typical products, radiator fins are typical products, and boiler drums are also typical products. Also requiring stamping processing are silicon steel cores for motors and electrical appliances, which are important basic materials for power equipment.

Products such as instruments and meters, household appliances, office machinery, and storage containers also use a large number of stamped parts. The daily output, which can reach hundreds of pieces per minute, makes stamping a very popular production method in modern factories.

Key points of part structure design

When designing the structure of stamped parts, simple and reasonable surface combinations should be used as much as possible to reduce the number and area of processed surfaces. The simpler the structure, the longer the life of the mold and the lower the production cost.

The prerequisite for the quality of stamping parts is to have good formability. The material must have good plasticity. The material must also have the characteristics of a small yield-to-strength ratio. The material must also have the characteristics of a large plate thickness directional coefficient, so as to ensure smooth deformation and stable product quality.

Scientific approach to material selection

The materials used for stamping must meet the technical requirements given by the product design on the one hand, and on the other hand must meet the conditions required for the stamping process and subsequent processing. The processing and stamping process of small hardware parts such as electroplating and cleaning also have specific requirements for the surface condition of the material.

The separation process does not require the material to have extremely good plasticity. However, moderate plasticity can avoid premature separation of the material. When selecting materials, it is necessary to comprehensively consider the stamping performance and subsequent processing requirements.

The function and selection of stamping oil

The selection of stamping oil must not fail to meet the process requirements. Stamping oil with excellent performance can significantly improve the processing environment, reduce mold wear, and improve the accuracy and surface quality of the workpiece.

It is suitable for stamping oil to reduce production costs. It has the properties of lubrication and friction reduction, and the ability to cool down. It also has the effect of preventing rust and corrosion. It is a key factor in the stamping process that cannot be ignored.

Precision control and cost balance

When parts are processed, the cost will increase as the accuracy increases. Therefore, for stamping parts, the surface roughness should be reasonably specified based on the actual needs of the mating surface. And don’t blindly pursue high accuracy.

The methods used to manufacture blanks include profiles, casting, forging, stamping, welding, etc. When selecting methods, production batches, material properties, and processing possibilities need to be considered to find a balance between cost and quality.

3. Safety Operating Procedures

3. Safety operating procedures

Safety preparation before work

Before starting riveting and welding operations, it is necessary to conduct a comprehensive inspection of the working environment. Make sure that the ventilation conditions of the site are good, the lighting is sufficient and there are no dark corners, and the equipment and facilities are in good condition and there is no damage. This is a basic step to ensure that subsequent operations can be carried out safely and must not be taken lightly or carelessly.

Personnel involved in the operation must hold valid qualification certificates and have a clear understanding of the equipment's operating procedures and safety precautions. Personnel who have not received professional training are strictly prohibited from operating alone to prevent safety accidents caused by unfamiliarity with the equipment.

Standards for wearing labor protection products

Personnel engaged in riveting and welding operations must wear safety protective equipment that meets standards, including hard hats, flame-retardant overalls, protective gloves, goggles, and protective shoes, etc., each of which is a barrier to protect life.

Protective glasses can effectively block the damage to the eyes caused by the welding arc light, thereby preventing the corneas from being burned. As for work clothes, you should choose pure cotton or flame-retardant materials to prevent synthetic fibers from melting when encountering high temperatures and then adhering to the skin, ultimately causing secondary damage.

Safety points for welding operations

When performing welding operations, be sure to ensure that the equipment is in good grounding condition and that the cables are not damaged or aged. If you use welding equipment that is damaged or aged, it is very easy to cause an electric shock accident, so it must be replaced as soon as possible.

During welding, it is absolutely forbidden to extend your head, hands and other body parts within the range covered by the arc light. The reason is that strong arc light can cause people to suffer from electro-optical ophthalmia, and high-temperature welding slag can easily cause serious burns, so a safe distance must be maintained. Obvious and visible warning signs should be set up in the operating area to prohibit entry by persons unrelated to the operation.

Protection requirements for cutting operations

Before engaging in cutting operations, be sure to clear away flammable and explosive items in the surrounding area and equip yourself with sufficient fire extinguishing equipment. When metal is cut, a large number of sparks will fly out. Once these sparks ignite combustible materials, the consequences will be unimaginable.

When operating cutting equipment, protective tools must be used to maintain a stable distance between the equipment and the workpiece. The workpiece must be firmly fixed to prevent it from moving during the cutting process and causing accidental injury. After cutting, the slag and waste materials must be cleaned up immediately.

Implementation of environmental protection measures

During riveting and welding operations, a large amount of smoke, dust and harmful gases will be produced, so it is necessary to ensure that the ventilation facilities in the workshop can operate normally. The smoke generated by welding contains manganese, chromium and other harmful substances to the human body. If inhaled for a long time, it will seriously affect the health of the respiratory system.

After the work is completed, the site must be cleaned immediately to eliminate fire hazards and the risk of puncture wounds. Waste welding rod heads and metal scraps should be collected in categories and cannot be discarded casually.

When an electric shock accident occurs, the first thing to do is to immediately cut off the power supply and use insulating objects to remove the electric shock victim from the power supply. Immediately carry out first aid measures such as cardiopulmonary resuscitation, and at the same time make an emergency call.

On-site fire-fighting equipment should be quickly used to extinguish the initial fire. Once a fire is discovered and the fire gets out of control, personnel should be evacuated immediately. Each equipment has a corresponding emergency response process. Operators must be proficient in it and participate in emergency drills regularly.

Didn't Expect It! These Old Shops In Jiading Are Still In Business, Have You Been There? ④

Didn't expect it! These old shops in Jiading are still in business, have you been there? ④

There is a small shop in Loutang Old Street in Jiading. It is not very eye-catching and has no formal signboard. There is a sign for white iron processing and a key hanging at the door. The owner is Tang Junchang. He is 75 years old. More than 30 years have passed since he opened the shop here. If you include his early studies in crafts, he has been dealing with tin for more than 60 years.

Old craftsmanship in jingle bells

Galvanized on the surface of tinplate, its thickness is less than one millimeter. It is lightweight, rust-proof and low-priced. In the past, every household loved it. At the age of only 14, Tang Junchang learned skills from a master, specializing in repairing agricultural and household appliances such as aluminum pots, buckets, and potion dispensers. Cutting iron sheets may seem simple, but it is actually not easy to make a straight cut. If you have not practiced, the scissors will go crooked and you will not be able to do it at all.

In the 1980s, the efficiency of the valve factory declined, so he decisively stepped out and founded a new business on his own. Every day he kept polishing in the shop until late at night. When he got home, he lay down directly to sleep. In the process of manually folding white iron, it is necessary to achieve straight lines and flat surfaces. However, behind this is the process of hundreds of tempering. His right arm muscles are a whole circle thicker than his left arm.

Real Kung Fu within a few millimeters

You didn’t expect it when you were doing the processing! These old shops in Jiading are still in business, have you been there? ④. Tang Junchang first drew a pattern on the tin sheet, and then used a large iron cutter to cut out the shapes. Square, round, straight, and curved shapes all depended on the feel of his hand. Next comes the work of crimping, hammering, and splicing. This entire process basically does not require welding or rivets. It is possible to create a seamless and leak-proof container solely by hand.

His skills were not only used to make ordinary daily necessities, but he also did amazing and important work. When Shanghai Volkswagen first started producing Santana, the first batch of car wheel hub molds were made by this 75-year-old craftsman. He had never made anything like this before, but he had an idea in mind. He repeatedly calculated the size according to the shape, cut, shaped and adjusted it, and completed it smoothly and smoothly.

Reassurance for Neighbors

Over the years, Tang Junchang has been sending customized kitchen utensils, high-end sinks and trash can liners to high-star hotels, and his orders are at a steady state. He has also done some personal customization, such as a plane specially made for left-handers, or a chopstick cage that can be disassembled, which are rarely seen on the market.

He relied on his neighborly humanity to support his perseverance for decades. The tinkling sound on the old street has never stopped, like a seemingly silent declaration that actually contains some profound meaning: Even though the times have changed, there are still people who are willing to engage in and complete certain things at a slow pace and with a serious attitude.

Manual temperature control cannot be learned by a machine

When processing white iron, we rely entirely on manual folding and pressing. Every cut and every beat must be done carefully. Machines can perform mass production, but fine work still relies on human hands and rich experience. Tang Junchang's right arm is thicker than his left arm. This is the mark left by more than sixty years of constant hammering.

Today, the number of people who master this craft continues to decrease, and young people are reluctant to learn it. The experience can be boring and difficult. However, he holds the idea that as long as there are people who need it, he will always insist on doing it. This is not just to make a living, but in a deep sense, it is his affection for this craft.

The old times hidden in the old streets

This small shop on Loutang Old Street only covers an area of 50 square meters. The walls are covered with various kinds of tin products, including spatulas, planers, air ducts, and sinks. This little shop is not a time-honored one, but it has been quietly sitting on the corner of the street for nearly half a century.

It is every old store that has the power to travel through time. Times are constantly changing, but the fireworks on the old streets have never dissipated. The tinkling sound is the most solid sound in the memory of old Jiading people.
