Raw material testing of Dongguan precision stamping parts manufacturers [hardware]

Material testing is a very important thing for Dongguan precision stamping parts manufacturers. It is the source of precision stamping parts, the starting point of quality assurance, the management verification of precision stamping parts manufacturers, and the quality standard of modern factories. As a manufacturer of precision stamping parts in Dongguan with 15 years of experience, how does hardware control the incoming inspection of raw materials? The first choice is to cooperate with some qualified and guaranteed raw material suppliers. For each batch of raw material procurement, the supplier's delivery must be accompanied by an SGS report and a material inspection report. After checking the 6 procedures, it will flow into the warehouse. The first is the appearance inspection of raw materials, whether there are scratches or bumps on the surface of the materials. The second is the material inspection of raw materials, which mainly inspects whether the grades are consistent and whether they meet the standards. Then there is performance testing, whether it is copper, steel or aluminum, whether it is consistent with the specified performance. Then there is the size inspection of the raw materials, whether it is consistent with the size of the purchase order, and is not within the tolerance range. In fact, for some materials with salt spray requirements, the salt spray time is tested on demand. After finishing this, we need to do the hardness test of the raw materials, whether it is consistent with the hardness of the material required by the customer, and whether it is consistent with the material used for proofing and opening. After completing these 6 process inspections, all of them are qualified, which is the beginning of a precision stamping part. With such a rigorous quality inspection and such a managed process, what can you hesitate about. Call the hotline:, the top ten, you can get a free design of 5800 yuan!
