1、 The mold surface modification technology uses plasma, laser, electron beam, high-density solar energy and other methods to make ion implantation to obtain surface modification.

2、 Surface coating technology refers to the use of various means of surface engineering to prepare various special functional coatings on the surface of products. With a very small amount of materials, a large number of expensive overall materials can play or difficult to play a role, while greatly reducing the processing and manufacturing costs of parts. The main feature of this technology is its strong applicability. Its methods include thermal spraying, electric spark coating, plastic powder coating, vacuum evaporation, sputtering coating, ion plating, chemical vapor deposition, molecular beam epitaxy, and ion beam synthesis thin mold technology.

3、 Composite surface technology applies two or more surface treatment methods to the treatment of the same workpiece, which can not only bring into play the respective characteristics of various surface treatment technologies, but also show the outstanding effect of combined use. The main applications of dies 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 coating and heat treatment, composite treatment process of coating and surface metallization, ion assisted coating, laser Electron beam composite vapor deposition and composite coating, as well as ion implantation and vapor deposition composite surface modification.
