Screw header punch manufacturers tell you that the dimensional accuracy of metal stamping parts refers to the difference between the actual size of the stamping parts and the basic size. The smaller the difference, the higher the dimensional accuracy of the metal stamping parts. The main factors that cause the size error of metal stamping parts are:

1. Manufacturing accuracy of metal stamping die.
2. Metal stamping die assembly process.
3. The elastic recovery of the material after stamping.
4. The screw header punch manufacturer will tell you the accidental factors in the production process, such as inaccurate positioning and unstable material properties.
Screw header punch manufacturers tell you that the dimensional accuracy of metal stamping parts can generally be divided into two categories: precision grade and ordinary grade. Precision grade is the precision that can be achieved in stamping technology, while ordinary grade is the precision that can be achieved by more economical means.
The surface quality of metal stamping parts should not be higher than the surface quality of raw materials, otherwise it needs to increase the subsequent processing to achieve, which increases the production cost. Screw header punch manufacturers tell you that we have a complete quality management system, which can effectively control the generation of defective products through various testing methods.
