The design of metal stamping parts, under the guarantee of normal use, as far as possible to make the dimensional accuracy grade and surface roughness grade requirements are lower, and is conducive to product exchange, reduce waste products, ensure product quality stability. Principles of hardware stamping parts design:

1, the design of metal stamping parts, under the condition of ensuring the normal use, as far as possible to make the dimensional accuracy level and surface roughness level requirements are lower, and is conducive to the exchange of products, reduce waste products, ensure the stability of product quality.

2, the design of metal stamping parts, should be conducive to the use of existing equipment, process equipment and process flow for processing, and conducive to the extension of the service life of the die.

3, the design of metal stamping parts must meet the product use and technical performance, and can be easy to assemble and repair.

4, the design of metal stamping parts must be conducive to improving the utilization rate of metal materials, reduce the variety and specifications of materials, as far as possible to reduce the consumption of materials. Use inexpensive materials where possible to make parts scrap free and less scrap blanking. Design of stamping parts must be simple shape, reasonable structure, to help simplify the mould structure, simplify the process number, which is the least, the most simple stamping process to complete the whole parts processing, reduce processing with other methods, and is advantageous to the stamping operations, is advantageous for the organization to realize mechanization and automation production, in order to improve labor productivity.
