    Wrong choice of cutting fluid will cost you half the processing cost

    When many factories perform machining operations on metal parts, they only care about the tool and speed, but they ignore the important function of cutting fluid. In 2025, there was a mold factory in Dongguan. Due to the use of poor quality cutting fluid, the surface roughness of the workpiece exceeded the standard, resulting in the scrapping of a total of 3,000 parts, resulting in a loss of 150,000 yuan. The correct selection of cutting fluid will have a direct impact on product qualification rate and tool life.

    The more expensive the cutting fluid, the better, but the more matching it is, the better

    The cutting fluid used in cast iron machining is completely different from the cutting fluid used in aluminum alloy machining. When machining cast iron, you need a cutting fluid with strong cleaning and anti-rust functions. However, when machining aluminum alloy, you need to use an anti-oxidation cutting fluid. There is a precision parts factory in Shenzhen that used general-purpose cutting fluids without thinking during work. Eventually, some white spots appeared on the surface of the aluminum parts and corroded, causing the rework rate to suddenly soar to 30%!

    Three crimes of inferior cutting fluid destroying equipment and damaging products

    工业润滑油选型_金属零件加工切削液选用指南_劣质润滑油危害

    Let’s talk about the first case first. Insufficient lubrication caused the tool to wear faster. There was a drill bit that could have been used for 8 hours, but it was scrapped and thrown away after 3 hours. Let’s talk about the second case, its anti-rust ability is not enough. In 2024, there was a hardware factory in Foshan that used low-priced cutting fluid . The processed screws were rusty after only two days of storage, causing all transactions that the customer had reached to be returned. Finally, let’s talk about the third case. Its service life is too short and the frequency of odor emission is too high. It needs to be replaced in less than a week. As a result, the cost of labor and waste treatment costs have doubled.

    Zhonglian Gongrun supplies directly from the source, eliminating the need for intermediate links

    In the Pearl River Delta Metal Parts Processing Cutting Fluid Selection Guide , we have a physical warehouse with an area of ​​5,000 square meters, including hydraulic oil, gear oil, cutting fluid and other products. Previously, an auto parts factory in Panyu, Guangzhou had been purchasing goods from agents. At that time, the price of a barrel of cutting fluid was 80 yuan more expensive than now. Since receiving the direct supply service, the factory has saved more than 30,000 yuan in fuel costs within a year, and the product quality is stable and reliable. The frequency of waste liquid treatment has also been significantly reduced from twice a month to once every six months.

    Accumulated practical experience in serving more than 1,000 factories for ten years

    There are guides on the selection of cutting fluids for processing metal parts after the mold steel is quenched and then cooled, to lubricated during tapping of stainless steel. We have handled hundreds of various processing scenarios. In 2023, there was a pump and valve factory in Zhongshan. Due to insufficient cooling of the cutting fluid, problems such as thermal deformation of the workpiece occurred. After we went to the site for debugging operations, we adjusted the concentration of the cutting fluid from 5% to 8% and switched to a specialized extreme pressure product. Ultimately, the scrap rate dropped directly from 12% to less than 1%.

    You just need to tell me the equipment and materials and I will prepare a plan

    It is unnecessary to study professional parameters such as viscosity and additives yourself. As long as you explain what metal material you are processing and what kind of machine tool you are using, I will be able to give you a matching solution. Just like when machining titanium alloy, what is needed is a high extreme pressure cutting fluid, but for ordinary carbon steel, a general-purpose cutting fluid will suffice. We provide a service of sending free samples for testing. If you are not sure, try it first before purchasing.

    How to choose industrial lubricants when purchasing cutting fluids? As an equipment engineer with 10 years of experience, what is your biggest headache? Is it the numerous and complicated models that make you dazzled, or is it the chaotic price that makes you afraid of being cheated?

  • Lele Blister Tray: Using Hard-core Data To Reveal The "efficient Guardian" Of Industrial Packaging

    Lele Blister Tray: Using Hard-core Data To Reveal The "efficient Guardian" Of Industrial Packaging

    Lele blister tray: using hard-core data to reveal the "efficient guardian" of industrial packaging

    Many factories encounter mutual constraints between cost, protection and efficiency when selecting hardware parts packaging. They worry about moisture when choosing paper pallets, and worry about insufficient load-bearing when using ordinary plastic trays. Frequent replacement of packaging will also increase hidden expenses. Relying on a clear set of data and measured performance, blister pallets are gradually becoming the mainstream solution to resolve these contradictions.

    What is the process of blister tray?

    In the production process of blister trays, thick sheet blister technology is used. Hard plastic sheets made of PET or HDPE are heated to 180 to 220 degrees. The material becomes soft due to the heat, and then is formed by vacuum adsorption, and then undergoes cooling and cutting steps. The pallets produced through this process have no seams and can closely fit the shape of the hardware parts. Compared with injection molded pallets, blister molds are cheaper and more flexible in modifying dimensions.

    The main specifications of the blister trays produced by Lele Packaging are thick sheets of 2 to 8 mm, which are significantly different from ordinary thin sheet products of 0.2 to 1 mm. During production, automated servo equipment is used, and the dimensional tolerance is controlled within plus or minus 0.15 mm. A set of molds can be punched 800,000 times, and the production pass rate of a single batch is stable at more than 98.5%, thus ensuring product consistency during batch supply.

    Load-bearing and durability measured data

    The most critical indicator of hardware parts packaging is load-bearing capacity. Lele blister pallets are designed with reinforced rib structures. Under laboratory conditions, the standard pallet is 1200 mm by 1000 mm, and its load-bearing capacity can reach 6 tons, with a static load of 1.5 tons per square meter. During dynamic handling, the pallet can also withstand 1.2 tons of goods when operated by a forklift or AGV trolley, thereby meeting the needs of intra-workshop transfers.

    In terms of durability, the material chosen for the pallet is food-grade HDPE, which has a temperature resistance range from minus 20 degrees to 40 degrees above zero. A third-party testing report shows that the pallet did not appear damaged after a drop test from a height of 3 meters, and its impact strength retention rate exceeded 90%. In normal recycling scenarios, a pallet can be used for 5 to 8 years, but ordinary paper pallets can only be used for 3 to 6 months.

    Material safety and environmental protection indicators

    The particles used in Lilo's blister trays are all new HDPE and PP, without any recycled waste. Its products have passed the national food contact material safety certification, and the standard number is GB/T 4806.7-2016. This shows that the pallet is non-toxic, odorless, will not mold, can directly contact hardware parts, and will not contaminate precision electronic components or painted parts.

    In terms of environmental protection, HDPE material has a high recycling value. After used pallets are cleaned, crushed, and re-granulated, the recycling rate can reach 83%. Compared with disposable wooden pallets or paper pallets, the solid waste generated by blister pallets during the entire life cycle is reduced by more than 70%. For companies with carbon emission assessment requirements, replacing recyclable blister pallets is a carbon reduction measure that can see immediate results.

    Real ledger to reduce costs and increase efficiency

    A Lelo blister pallet of model 1210 weighs 12 kilograms, but a wooden pallet of the same specification weighs 35 kilograms. The lightweight design can directly reduce shipping costs. If a truck is loaded with 100 pallets, blister pallets can increase the volume of single-vehicle transportation by 40% and reduce annual logistics costs by more than 15%. For a hardware factory, if its daily shipment volume is large, the cost savings can be considerable.

    It has obvious advantages in storage space and cleaning costs. The pallets can be nested and stacked, saving 55% of the warehouse area when not in use. They are suitable for high-density storage. The surface is smooth and resistant to oil stains, and can be restored to cleanliness by washing with a high-pressure water gun. No additional disinfection or drying is required. The "efficient guardian" of industrial packaging is revealed with hard-core data. The annual maintenance cost of each pallet is 60% lower than that of wooden pallets, and the cumulative savings in five years exceeds 300 yuan.

    Which hardware parts scenarios are suitable?

    五金零件包装方式有哪些_吸塑托盘工艺参数_力乐吸塑托盘

    Lele blister pallets have served more than 2,000 companies, and their annual shipments have exceeded 1 million. In the field of hardware parts, there are mainly three scenarios: for example, precision stamping parts such as mobile phone middle frames and connectors are fixed with customized grooves to prevent bumps; automotive parts such as brake pads and pipe clamps use reinforced rib structures to achieve multi-layer stacking; standard parts such as screws and nuts rely on modular pallets to achieve counting and sorting functions.

    Actual cases show what are the packaging methods for hardware parts . There is a fastener factory with an annual output of 50 million screws. It first used blister trays, and then the packaging damage rate dropped from 3% to less than 0.5%, saving 40% of warehouse space. Then, another auto parts supplier stated that after the pallet was recycled for two years, there was almost no degradation in appearance and performance, and the single-use cost was reduced to 0.8 yuan.

    Comparison with common packaging methods

    There are a large number of factories, and until now, they are still using cartons and partitions to package hardware parts . What are the methods of packaging hardware parts ? However, cartons are not moisture-proof. During the rainy season in the south, they are prone to softening and collapse, causing friction between many parts. Plastic woven bags are cheaper, but they cannot provide fixed protection at all. During transportation, hardware parts may be scratched or deformed due to collisions. The blister tray uses profiling design to fix each hardware part in its own groove, completely eliminating the occurrence of collisions from the source.

    Compared with injection molding pallets, the mold opening cost of blister pallets is reduced by more than 70%, and the mold modification cycle is shortened by half. For hardware parts factories, if they have a wide variety and small batches, blister pallets can flexibly cope with the need for frequent production changes. Compared with wooden pallets, blister pallets do not have wood chips falling off and contaminating parts, and there is no risk of iron nails scratching the products. They have significant advantages in terms of cleanliness.
