Three elements of stamping

Metal sheets, molds and equipment are the three elements of stamping.

Sheet: The surface and intrinsic properties of the sheet for stamping have a great influence on the quality of the stamped product.

There are 6 points for stamping materials:

1 The thickness is accurate and uniform.

2 The surface is smooth, no spots, no flaws, no scratches, no surface cracks, etc. Prevent the generation of scrap.

3 The yield strength is uniform and there is no obvious directionality. In order to reduce the occurrence of defective or scrap

4 Uniform elongation is high. In order to prevent uneven deformation.

5 The yield ratio is low. In order to improve the accuracy of the bending parts.

6 Low work hardening.

Mold: The accuracy and structure of the mold directly affect the forming and precision of the stamping. Mold manufacturing costs and longevity are important factors influencing the cost and quality of stampings.
