Design work of Dongguan stamping parts:

1. The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.

2. The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. Use low-cost materials where possible, and make parts as scrap-free and blank as possible.

3. The stamping parts designed by Dongguan stamping parts must be simple in shape and reasonable in structure, so as to facilitate the simplification of the mold structure and the number of processes, that is, to complete the processing of the entire part with the least and simplest stamping process, and reduce the use of other methods. Processing, and is conducive to stamping operations, easy to organize the realization of mechanized and automated production, in order to improve labor productivity.

The hardness testing of stamping industry can be divided into the following three parts:

1. Incoming inspection of raw materials.

2. The hardness test of the mold.

3. Hardness testing of intermediate products of stamping parts and finished stamping parts.
