With the development of the manufacturing industry, the processing technology of hardware molds will move towards a highly automated, intelligent and precise direction. Enterprises need to increase investment in technological research and development, introduce advanced technologies and equipment, such as high-precision numerical control processing technology and intelligent manufacturing systems, in order to improve product quality and reduce production costs.

The die used for metal stamping dies is called a stamping die, or simply a die for short. Stamping dies are specialized tools for batch processing materials (metals or non-metals) into the required stamped parts. Meanwhile, in modern manufacturing, metal stamping dies are the core tools for batch production of metal components, and their processing quality directly affects the precision, efficiency and cost of the products. The processing of metal stamping dies is a complex systematic project integrating design, precision processing, heat treatment and assembly and debugging. Its core lies in ensuring the dimensional accuracy, surface quality and performance of the dies through reasonable process planning and high-precision processing.

First of all, surface treatment methods should be classified, which may be divided into coating technology, surface modification technology, composite treatment technology, etc The surface treatment technology of molds mainly changes the microstructure, chemical composition or stress state of the mold surface through surface coating, surface modification or surface composite treatment technology. There are many surface treatment techniques and methods used on molds, which can mainly be summarized as:
