What Factors Can Cause Metal Stamping Parts To Warp Unevenly

What factors can cause metal stamping parts to warp unevenly?
In hardware stamping parts processing factories, the raw materials used to process hardware stamping parts are mostly metal sheets or strips, and most of them are thin materials. Therefore, sometimes the processed stamping parts will be warped and uneven. So what factors cause stamping parts to warp unevenly? Find out below.
1. The punching gap of the mold will cause the stamping parts to warp.
2. If the die hole is not vertical and has a reverse taper, it will cause the stamping parts to warp.
3. The complex structure and shape of stamping parts leads to uneven shear force around the parts, resulting in warpage.
4. Internal stress in metal materials can also cause warping.
5. Contact between metal materials and undesirable factors such as oil, air, etc. may also cause warping of the parts during stamping processing.
Stamping parts manufacturers, if they understand the factors that cause uneven warping of stamping parts, can take corresponding measures in advance to reduce the occurrence of uneven warping stamping parts and improve the quality of metal stamping parts.
