In the modern machinery manufacturing industry, the mold industry has become a very important industry in the national economy. The development of many new products depends to a large extent on mold manufacturing technology, especially in automobiles, light industry, electronics and aviation. It is particularly important in such industries. The key to the development of the mold industry is the progress of mold technology, which involves the intersection of multiple disciplines. As a high value-added and technology-intensive product, the level of its technical level has become one of the important indicators to measure the manufacturing level of a country. Therefore, advancing with the times, the manufacturing industry has rapidly promoted many advanced mold manufacturing technologies. The surface engineering technology of mold processing manufacturers is a systematic engineering that obtains the required surface properties by changing the morphology, chemical composition and structure of the solid metal or non-metal surface. There are three main categories as follows:
1. Mold surface modification technology uses plasma, laser, electron beam, high-density solar energy and other methods 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. A very small amount of material can cause a large number of expensive overall materials to be able to or difficult Play a role, while greatly reducing the processing and manufacturing costs of the 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, ion beam Synthetic thin mold technology, etc. , The composite surface technology uses two or more surface treatment processes in the treatment of the same workpiece, which can not only give play to the respective characteristics of various surface treatment technologies, but also show the outstanding effect of combined use. The main application of the mold is the composite surface chemical treatment, the composite strengthening treatment of surface heat treatment and surface chemical heat treatment, the composite treatment process of heat treatment and surface deformation strengthening, the composite treatment process of plating layer and heat treatment, and the composite treatment process of covering 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.
