Stainless steel stamping is the process of stainless steel material processed by using the mold, which makes its deformation or fracture has a certain shape and size.
Orienson's stainless steel metal stamping
Metal stamps for stainless steel possesses good mechanical performance as well as high hardness, good wear-resisting performance, corrosion resistance, high temperature resistant, and so on. Under the harsh environment, stainless steel is more resistant to corrosion than other materials, also with longer service life, and is widely applied in various fields.

What Are Problems We Need To Pay Attention To When Design Stainless Steel Stamping Parts
Understanding the characteristics and processing characteristics of stainless steel material is the key factor to ensure the quality of stainless steel stamping kit, the hardness and strength of stainless steel material are relatively high, we should pay attention to the following problems when design:
1. The material rebound deformation
Metal materials will rebound after stamping molding, due to the high hardness of stainless steel, the material rebound is larger. In the design of the molding mold, it is necessary to predict the amount of material rebound and minimize the size problems caused by material rebound.
2. Heat treatment
Much stainless steel stamping and drawing parts will be required higher hardness, but because the harder the material is, the more difficult it is to stretch, sometimes it is necessary to reheat after molding to achieve hardness requirements, but the workpiece after heat treatment is prone to deformation, and the deformation should be taken into account in mold design.
3. Tool selection
The hardness of stainless steel is high, the loss of the die blade will be relatively large, so when choosing a tool, you need to make the appropriate choice according to the hardness of stainless steel material.
As one of the most professional metal stamping manufacturer, we provide metalwork and stamping, stamped aluminum panels, simple press tool, single station press, deep drawing and etc. Want to know more, contact us.
