What are the solutions to the high scrap rate of metal stamping parts manufacturers

Excessive scrap rate of metal stamping parts manufacturers will increase production costs. This requires us to combine actual production, optimize production processes from multiple angles, improve production procedures, provide raw material utilization rates, and increase quality control capabilities. So what are the specific solutions, let's take a look. 1. Precision metal stamping parts processing manufacturers analyze the reasons for the high rejection rate (1) The imported materials do not meet the standards, the performance is unstable, and the dimensional tolerances are large, which leads to unqualified accuracy. (2) The mold is not installed correctly. (3) During the unloading process, the operator did not install the feeding positioning device. (4) After the mold is used for a long time, the gap becomes larger and the parts wear out. (5) During stamping, the mold bears excessive impact force, which causes the bolts or parts to loosen and affects the quality. (6) The stamping personnel did not work in accordance with the operating manuals formulated by the company. 2. Solutions proposed by precision stamping processing manufacturers (1) When purchasing raw materials, the selection must be strictly in accordance with the production standards. If the factory conditions permit, the steel composition, surface roughness and dimensional accuracy should be tested. Qualified raw materials are the prerequisite to ensure the quality of stamping parts. When purchasing raw materials, choose regular steel distributors or choose from large steel plants. (2) After designing the stamping process, the stamping workers must strictly abide by the process regulations during the operation. Each stamping product has a different stamping process, which requires the manager to formulate a specific product before processing the product. (3) The punches and stamping dies used in the factory must always be in a stable operating state, and they must be regularly maintained and overhauled. (4) Develop a complete quality inspection charter. The first batch of products must undergo full/face-to-face testing before formal production, and sample testing must be performed regularly during the production process. (5) Use appropriate tools for feeding to avoid scratching the product. (6) When stamping, pay attention to keeping the mold clean, and the workpieces and raw materials in the workshop should be placed in an orderly manner.
