Take you to understand how the stamping factory controls raw materials?

I believe that many purchasing personnel in stamping processing plants will be troubled, how to control the purchased raw materials? Today, let the author take you to analyze: 1. The stamping processing plant needs to have a stable and large-scale raw material manufacturer, instead of frequent replacement. The purchase point here today will be there tomorrow. Because each stamping parts processing plant has its own product design habits, there will be some small differences. 2. The stamping processing plant needs to have a qualified material report for each incoming material, organize and file, and compare. The time for each master batch to be divided will be slightly different, but it will not affect the use. 3. The stamping factory cannot change the material at will without notice, and keep it confidential. Hardware, a stamping processing factory with fixed and qualified large-scale suppliers supplying raw materials, with 15 years of professional experience, more than 20,000 sets of molds in more than 20 industries, more than 100 sets of mold processing per month, and a daily production capacity of 3 million impressions. : Same number on WeChat
