Factors influencing the dimensional accuracy of metal stamping parts
Different metal stamping products have different requirements for accuracy. As long as we meet the accuracy requirements of customers and comprehensively consider production costs, we can produce qualified stamping parts. The factors that affect the dimensional accuracy of metal stampings must be known by everyone. Let’s have a look together.
The dimensional accuracy of metal stamping parts refers to the difference between the actual size of stamping parts and the basic size. The smaller the difference, the higher the dimensional accuracy of metal stamping parts.
The influencing factors are as follows:
- Manufacturing precision of metal stamping die.
- Gap between male and female dies.
- Elastic recovery of materials after stamping.
- Accidental factors in the production process, such as inaccurate positioning, unstable material performance, etc.
It can be divided into precision level and ordinary level. The ordinary level is the precision that can be achieved by more economic means, while the precision level is the precision that can be achieved by stamping technology.
The surface quality of metal stampings shall not be higher than that of raw materials, otherwise, subsequent processing is required to achieve it, increasing production costs.
