The drywall screw heading die manufacturer tells you that the dimensional accuracy of metal stamping parts refers to the difference between the actual size of the stamping part and the basic size. The smaller the difference, the higher the dimensional accuracy of the metal stamping part. The drywall screw heading die manufacturer tells you that 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. Accidental factors in the production process, such as inaccurate positioning, unstable material properties, etc.
The drywall screw heading die manufacturer tells 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 drywall screw heading die manufacturer tells you that when the manufacturing precision of the mold is high, the dimensional accuracy of metal stamping parts can reach ITl0 level, and the inner hole size can reach IT9 level.
The drywall screw heading die manufacturer tells you that the surface quality of the metal stamping parts should not be higher than the surface quality of the raw materials, otherwise it needs to increase the subsequent processing to achieve it, which increases the production cost.
