How To Judge The Strength Of Custom Metal Processing Manufacturers?

How to judge the strength of custom metal processing manufacturers?

When many purchasers are working, they will step into pitfalls and suffer losses because they mistakenly believe in the so-called "very experienced" statement. When you are judging whether a metal processing customization manufacturer is truly reliable, you must not listen to fancy propaganda without actual content. You only need to keep a close eye on the three very critical hard indicators of equipment configuration, technical team and service process.

Equipment lists are more useful than slogans

The processing accuracy of metal depends on the equipment. For plates and pipes with thicknesses within the range of 0.5 mm to 20 mm, a high-power laser cutting plate machine must be used and a pipe cutting machine must be used to complete the work.

For those parts with relatively complex structures, the forming process requires the collaborative operation of CNC bending machines and laser welding machines. Only when all the process methods of gas shielded welding, argon arc welding and medium frequency welding are fully equipped, can we fully cover materials with different characteristics such as carbon steel, stainless steel and aluminum plates.

When conducting on-site inspections, you must directly request documents containing a detailed list of equipment and specific parameter descriptions from the other party. Do not simply believe those empty claims that verbally claim to have multiple processing capabilities and can operate everything.

To give a specific example, there is a company that was established in 2017. It has deployed a fully functional set of professional machinery and facilities required for laser processing and welding operations in a factory with an area of ​​3,000 square meters. By making the description of the equipment more specific and clear, it can effectively prove to the outside world that the company has real actual production operation capabilities. This kind of display based on specific equipment conditions is obviously much more credible and reliable than the vague and vague marketing content.

Technicians are harder to buy than equipment

The equipment can be purchased at a cost of several million, but a bending master who has been working for ten years is not easy to find. During the inspection, focus on asking about the proportion of technical personnel and their years of experience. In a company with more than 20 people, if there are 6 core technical personnel, they can control the entire process from drawing review to production implementation, so that they can meet non-standard needs.

On the other hand, if the other party only verbally claims that it can do it without any problems, but cannot answer when asked about the control measures for welding deformation, the compensation plan for material rebound, and the specific distribution of tolerances, then it can basically be determined that it is a casing workshop without core technology.

Don't be fooled by the so-called masters with many years of industry experience. The key is to see what actual projects they have worked on to judge their true level.

Prototyping speed reveals real production capacity

Reliable manufacturers have a fixed time period from receiving drawings to taking out samples. Normally, small batch trial production only takes three to five days.

If you encounter a situation where the quotation is ridiculously low, but you have to wait for more than two weeks for proofing, it is most likely because the production equipment is queued up, or the work is outsourced. Such a situation is very insecure for subsequent large-volume delivery, so don’t suffer a big loss just for the sake of small gains.

Judging this method is straightforward. You need to ask the manufacturer to write the proofing cycle into the contract, and you also need to ask the manufacturer to write the delivery date into the contract. If the deadline is exceeded, payment will be deducted. That verbal promise to go as fast as possible is non-binding. Only words in black and white can force the other party to prioritize production scheduling. If you omit this step, the probability of disputes will double.

Quality control records are more effective than certificates

Systematic manufacturers have process inspection records for each process, and a test report is attached to the factory. You can ask to see the inspection ledgers of the last three shipments. The key point depends on whether the key dimensions are fully inspected or randomly inspected. It also depends on what the sampling ratio is. At the same time, it is necessary to find out how defective products are handled.

A so-called ISO certificate has little actual value. Because there is a possibility that the certificate will expire, it is not even possible to rule out the possibility that it was purchased through informal means.

In order to conduct a more effective screening, it is recommended that you ask the manufacturer to display a third-party testing report issued within the last six months. In the report, the full name of the testing agency and the specific standard number it is based on must be clearly stated. Cross-validation analysis through this written material is used to determine whether the accuracy of the equipment truly matches the actual needs. Compared with the manufacturer's self-statement, such an approach is more reliable and convincing.

Emergency response determines the size of the loss

Once the production line is stopped waiting for parts, the loss may be as high as tens of thousands of dollars every day. It is recommended to ask the manufacturer directly if they can guarantee a technical response within four hours and supplement the corresponding parts within 48 hours.

If the other party can give a clear answer and provide specific operating procedures, it means that the factory has a material preparation mechanism and emergency production planning plan, rather than a plan made to cope with temporary situations.

Customers who need accessories such as equipment casings and racks must confirm whether the manufacturer can provide installation guidance and after-sales maintenance. Don't wait until the parts are delivered to the site only to discover that the dimensions are wrong but there is no one to ask. If this step is not done well, it will definitely be full of trouble later.

Don’t be kidnapped by size and age

The reliability of an old factory that has been established for 20 years is not necessarily higher than that of a new factory that has only been in operation for three years. The key lies in whether the equipment has been updated and whether the core personnel are still employed. Some old factories have not made any changes to their equipment for more than ten years, and their accuracy has long been unable to meet qualified standards. Simply relying on so-called "experience" as a promotional bargaining chip is not sufficiently convincing. Consumers should not be confused and intimidated by the years of operation of the factory.

Before making a final decision, you can invite more than two manufacturers to have a video call or on-site visit to see what typical products are like, so as to compare the actual use status of the equipment and the management level in the workshop. Don't be led in by pure price arguments. You must judge from the perspective of actual processing capabilities, so as not to be deceived. You must also take a closer look at the real cases used by typical customers. Don’t just stare at the carefully packaged appearance on the official website.
