How Can Precision Stamping Parts Achieve High Quality?

Precision Stamping is the use of stamping equipment so that the sheet metal is deformed by the deformation force in the mold to obtain a stamping part of a certain shape. The parts processed by this processing method have high precision, smooth surface, and good quality, and can be produced on a large scale with high production efficiency. It can also process various metal materials. To do a good job in precision stamping, the processing materials, molds and the three must meet the stamping requirements, that is, if there is one unqualified, the quality of the stamped parts will not be so good, and it will not meet the precision stamping process. So what are the requirements for precision stamping materials? Let's take a look

Precision stamping processing its requirements on materials:

For the material to be stamped and added, it must have high plasticity and toughness. Generally, carbon steel elongation δ≥16%, yield ratio σs/σb≤70%, low-alloy high-strength steel δ≥14%, σs/ σb≤80%. Otherwise, the stamping performance is poor, and certain measures must be taken in the process, thereby increasing the manufacturing cost of the parts. We must choose high-quality materials when selecting materials. If the material quality is poor, it will affect the post-processing effect and will not meet the precision processing requirements.

In the process of precision stamping, there will always be various problems, such as scratches on the surface of the processing bending parts, indentations on the surface of the stamping parts, etc., then in the face of various problems, we need to analyze and deal with them until they are processed. The quality of the drawing and pressing parts is qualified. If you have a surface scratch problem and don't know how to fix it, take a look.

The main reason for this problem is that metal particles or dust particles stick to the surface of the working part during the bending process of the processing material, which causes the Precision Stamping Parts to be scratched. In addition, the bending direction is parallel to the rolling direction of the material, which will cause cracks on the surface of the workpiece and reduce the surface quality. In addition, the radius of the concave and convex die is too small, which will also cause cracks in the bending part of the workpiece. If the gap between the concave and convex die is too small, it will also cause scratches on the surface. When the depth of the punch into the die is too large, the surface of the Precision Metal Stamping Part will also be scratched. If you make the above mistakes, you can correct them in time and you can process stamping parts with smooth surfaces.
