Most of the precision metal stamping processing plants in the processing of stamping parts, often appear reject rate is too high. Now the competition in the stamping industry is very fierce, and the profit space is also compressed very badly. If the rejection rate remains high, it is very possible to finish an order not only without profit but also lose money. It is particularly important to reduce the high rejection rate of precision hardware processing.
Precision hardware processing should pay attention to these problems, prevent and reduce the rejection rate:
1. All links stipulated in the process rules should be comprehensively and strictly observed.
2. The tools and equipment such as press and die used should be guaranteed to work in normal working condition, and daily testing and maintenance should be carried out at all times.
3. Raw materials are the first guarantee for processing qualified precision stamping parts. If the hardness and appearance of raw materials do not meet the quality requirements, then the corresponding reject rate of precision stamping parts will be too high.
4, in the stamping process to ensure the cleaning of the mold cavity, the workplace to tidy up the orderly processing of the workpiece to be placed neatly.
