Hardware tells you how to detect when selecting raw materials for automotive precision stamping parts Co., Ltd.

Some metal materials used in automobiles are mostly alloy steel, cast iron, copper, carbon steel, etc., and for the performance of such metal materials, most of the material's load-bearing, collision, corrosive and corrosive properties should be considered. Durability. And how does Auto Precision Stamping Co., Ltd. carry out pre-production inspections of these metal raw materials? Xiaoshuo sorted out a few of his company's processes for your reference: 1. Material testing of raw materials, mainly testing the factory report of the material, and whether the SGS report is consistent with the required metal properties. 2. Performance testing. Detect the performance analysis of this metal material, tensile test, torsion test, bending test and so on. 3. Dimension detection, whether the incoming material is consistent with the customized material in width and thickness. 4. Appearance inspection is to inspect the appearance of metal raw materials for defects, trachoma, scratches, etc. on the surface. 5. Salt spray test, according to the use of the product, the required salt spray time to do the salt spray test. 6. Hardness testing, use a hardness tester to test whether the hardness of the raw material meets the standard. Hardware, 15 years of ingenuity and focus on the metal stamping industry, perfect team, sophisticated equipment, strict quality requirements, is your reliable partner for choosing Automotive Precision Stamping Co., Ltd.
