Overview of Design Principles for Hardware Stamping Parts
08-21 / 2019

1. The designed stamping parts must meet the product usage 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 minimizing material consumption as much as possible. If possible, use low-cost materials to achieve scrap free and minimal cutting of parts.


3. The designed stamping parts must have a simple shape and a reasonable structure, in order to simplify the mold structure and simplify the number of processes, that is, to use the least and simplest stamping processes to complete the entire part processing, reduce the use of other methods for processing, and facilitate stamping operations, facilitate the organization of mechanized and automated production, and improve labor productivity.


4. The designed stamping parts, while ensuring normal use, should strive to have lower requirements for dimensional accuracy and surface roughness levels, and be conducive to product interchangeability, reducing waste, and ensuring stable product quality.


5. The designed stamping parts should be conducive to using existing equipment, process equipment, and processes to process them as much as possible, and be conducive to extending the service life of the stamping die.
