Description mold surface engineering of three main
In modern mechanical manufacturing, mold industry has become a very important national industry, many new product development and production, to a large extent dependent on the mold manufacturing technology, especially in the automotive, light industry, electronics and aviation industry of utmost importance. The key is to die for industrial development and technological progress die, tooling and technology also involves multidisciplinary. Mold as a high value-added and technology-intensive products, the level of its technical level has become a national manufacturing standards to measure an important indicator. Therefore, the times, the manufacturing industry quickly for a lot of advanced mold manufacturing technology. Surface Engineering Technology (SET)
Surface engineering technology is a solid metal or non-metallic by changing the surface morphology, chemical composition and structure, in order to obtain the required surface properties of systems engineering.
There are three main categories:
(1) surface modification by plasma, laser, electron beam, high-density solar energy and other methods to ion implantation, surface modification to obtain.
(2) Surface coating technology it refers to the use of various means of surface engineering, surface preparation products for various special features of the coating, with a very small amount of material can cause a whole lot of expensive materials that can be played or difficult to play a role, while greatly reducing the cost of processing and manufacturing workpiece. The main feature of this technology has strong applicability, the method of hot spray, spark coating, plastic powder coating, vacuum deposition, sputtering, ion plating, chemical vapor deposition, molecular beam epitaxy, ion beam synthesis of thin mold technology.
(3) composite surface technology to two or more of the surface treatment method used in the treatment of the same piece, not only can play a variety of characteristics of each surface treatment technology to better show the prominent effect of combination. Main applications are complex surface chemical treatment, surface treatment and surface treatment of composite chemical enhanced treatment, heat treatment and surface hardening of the composite process, the plating layer and the heat treatment of the composite process, cover and surface metallurgy technology of the composite process, ion-assisted coating, laser, electron beam vapor deposition and composite compound and coating deposition and ion implantation and surface modification compound.
