In the modern machinery manufacturing industry, the mold industry has become a very important industry in the national economy. The development and production of many new products relies heavily on mold manufacturing technology, especially in automobiles, light industry, electronics and Especially important in industries such as aviation. The key to the development of the mold industry is the advancement of mold technology, which involves multidisciplinary intersections. As a high value-added and technology-intensive product, mold technology has become one of the important indicators to measure the manufacturing level of a country. Therefore, with the times, the manufacturing industry has also rapidly promoted many advanced mold manufacturing technologies.

Surface engineering is a system engineering that changes the morphology, chemical composition, and structure of a solid metal or non-metal surface to achieve the desired surface properties.

There are three main categories:

(1) Surface modification technology Plasma, laser, electron beam, high-density solar energy and the like are used to implant ions to obtain surface modification.

(2) Surface coating technology It refers to the use of various methods of surface engineering to prepare various special functional coatings on the surface of the product. With a very small amount of material, a large amount of expensive whole materials can be caused or It is difficult to play, and at the same time greatly reduces the processing and manufacturing costs of the parts. The main feature of this technology is its strong applicability. The methods include thermal spraying, electric spark coating, plastic powder coating, vacuum evaporation, sputter coating, ion plating, chemical vapor deposition, molecular beam epitaxy, and ion beam. Synthetic thin mold technology, etc.

(3) Composite surface technology Two or more surface treatment methods are applied to the same workpiece, which not only can exert the respective characteristics of various surface treatment technologies, but also show the outstanding effects of combined use. The main applications include composite surface chemical treatment, composite strengthening treatment of surface heat treatment and surface chemical heat treatment, composite treatment process of heat treatment and surface deformation strengthening, composite treatment process of plating layer and heat treatment, composite treatment process of coating layer and surface metallurgy, Ion-assisted coating, laser, electron beam composite vapor deposition and composite coating, as well as ion implantation and vapor deposition composite surface modification.
