How to check the quality of stainless steel stamping parts

Stainless steel stamping parts are a common metal material stamping part in daily life. How to check the quality of stainless steel stamping parts after production? Precision has been engaged in the custom processing of precision metal stamping parts for decades, and I can share some experience in the quality control of precision stamping parts. 1. Material inspection The quality control of materials is divided into material acceptance inspection, material cleaning before and after inspection, and material inspection before production. The purpose is to confirm that the quality of the material meets the production requirements. 2. First piece inspection The first piece of stamping parts determines the quality of the whole batch of parts, and the first piece inspection is an important part of the whole batch inspection. In a specific way, observe whether the workpiece has bad phenomena such as bottom mark, cracking, wrinkle, deformation, etc. 3. First piece, middle piece, and tail piece extraction inspection The first piece, middle piece, and tail piece extraction inspection can better achieve quality control. 4. Online partition inspection 100% inspection of stamping parts is mainly achieved through partition inspection, including visual inspection and tools. 5. Inspection of the whole basket of parts The quality confirmation of the whole basket after the basket is installed can avoid the outflow of bad parts caused by the inapplicability of the basket and the work station equipment. 6. Parts accuracy detection Use tools to perform full-scale accuracy detection of the parts (first parts), which can give early warning to parts with large changes in the pass rate, so as to avoid affecting the dimensional accuracy of the entire vehicle. 7. Hand repair of defective products Hand repair of defective products refers to the complete basket and secondary selection inspection of the parts after the parts are trimmed. Its purpose is to repair the defects detected in each quality control item, avoid the outflow of defective products and reduce the loss of scrap. 8. Outgoing inspection of parts. This is the last pass in the quality control of parts. Reconfirmation of outgoing inspections can effectively avoid the outflow of defective products. Various quality inspection methods can be summarized as pre-production control, production control, and post-production control, which can achieve the purpose of 'not accepting defective products, not manufacturing defective products, and not outflowing defective products'.
