Metal stamping factory's testing standards for raw materials

With the various hardware stamping products we use in our daily life, the hardware stamping processing factory will be more strict in the purchase of raw materials, because only in this way can the accuracy of the hardware products be guaranteed, so how does the author’s company deal with it? What about raw material inspection? First of all, our stamping factory should inspect the surface of the raw material to see if there is any scratch deformation. Then check whether the external dimensions of the material meet the tolerance requirements? In testing whether the hardness of the material is qualified. If the above points are unqualified, the stamping factory cannot guarantee the accuracy of the products when producing hardware products. The above situation will not happen in the author's factory, because the author's factory has a stable large-scale raw material supplier, and the quality is guaranteed. The metal stamping factory has 15 years of production experience, a professional team of more than 20 people, and a strict raw material control process. It is your safe choice.
