A Brief Analysis Of New Surface Treatment Technology Of Die - Casting Mould

Die - casting mould is a kind of mould.With the rapid development of automobile and motorcycle industry in China, die casting industry has ushered in a new period of development.At the same time, it also puts forward higher requirements for the comprehensive mechanical performance and life of die casting mould.To satisfy the increasing use of performance requirements just rely on the application of new type mould materials are still hard to meet, all kinds of surface treatment technology must be applied to the die casting mould to reach to the die casting mould of surface treatment of high efficiency, high precision and high life.The working conditions of die - casting die - casting die - casting die - casting die - casting die.Pressure casting is the molten metal under high pressure, high speed, full of the mold and die casting molding, repeated contact with the hot metal in the process of work, so the die casting mould with higher thermal fatigue, thermal conductivity, wear resistance, corrosion resistance, impact toughness, red hardness and good mold release, etc.Therefore, higher requirements for die casting mould of surface treatment technology in recent years, all kinds of die casting mould surface treatment new technology constantly emerging, but in general can be divided into the following three categories: (1) the traditional heat treatment process improvement techniques;(2) surface modification technology, including surface heat diffusion treatment, surface phase change strengthening, electric spark strengthening technology, etc.;(3) coating technology, including chemical plating, etc.
