Different metal stamping parts 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 influencing factors of the dimensional accuracy of metal stamping parts must be known to everyone. Let's take a look at it together.

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 influencing factors are as follows:
1. Manufacturing accuracy of metal stamping die.Generally speaking, most mold parts are processed with medium wire. If the customer requires high-precision stamping parts, it must use slow wire processing
2. The gap of the concave and convex die.
3. The elastic recovery of the material after stamping.The properties of different materials are different, which will affect the incision, angle and burr of the stamping parts
4. factors in the production process, such as inaccurate positioning, unstable material properties, different press pressure, stamping speed etc.
It can be divided into two categories: precision grade and ordinary grade. The ordinary grade is the precision that can be achieved by more economical means, and the precision grade is the precision that can be achieved by stamping technology.
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.
