Injection mold steel hardening technology introduction



   In the work of the mold, in addition to the reasonable cooperation of the matrix with sufficient strength and toughness, the surface properties are critical to the working performance and service life of the mold. These surface properties are: abrasion resistance, corrosion resistance, friction coefficient, fatigue properties, and the like. These performance improvements, relying solely on the improvement and improvement of the matrix material, are very limited and uneconomical, and surface treatment techniques can often achieve twice the result with half the effort, which is why surface treatment technology has developed rapidly.


  The surface treatment technology of the mold is to systematically change the morphology, chemical composition, microstructure and stress state of the mold surface by surface coating, surface modification or composite treatment technology to obtain the desired surface properties. From the way of surface treatment, it can be divided into: chemical methods, physical methods, physical chemical methods and mechanical methods. Although new treatment technologies are being developed to improve the surface properties of molds, more major nitriding, carburizing and hardening film deposits are used in mold manufacturing.


1, Nitriding


  The nitriding process includes gas nitriding, ion nitriding and liquid nitriding. In each type of nitriding method, there are several kinds of nitriding techniques, which can adapt to the requirements of different steel grades and different workpieces. Because the nitriding technology can form a surface with excellent performance, and the nitriding process has good coordination with the quenching process of the die steel, at the same time, the nitriding temperature is low, and there is no need for intense cooling after nitriding, and the deformation of the mold is extremely small, therefore, the mold Surface strengthening is the earliest and most widely used nitriding technique.


2, Carburizing


  The purpose of mold carburizing is mainly to improve the overall strength and toughness of the mold, that is, the working surface of the mold has high strength and wear resistance. The technical idea introduced here is to reduce the manufacturing costs by replacing the higher-grade materials with lower-grade materials, ie by carburizing and quenching.


3. Hardened film deposition


  Hardened film deposition technology, currently more mature is CVD and PVD. In order to increase the bonding strength between the film layer and the surface of the workpiece, various enhanced CVD and PVD technologies have been developed.

  The hardened film deposition technology was first applied to tools (tools, cutting tools, measuring tools, etc.), and the effect was excellent. A variety of tools have been coated with a cured film as a standard process.


   Molds have been coated with hardened film technology since the 1980s. Under the current technical conditions, the cost of hardened film deposition technology (mainly equipment) is still high, and it is still only applied to some precision and long-life molds. If the method of establishing a heat treatment center is adopted, the cost of coating the cured film will be greatly reduced. . If more molds adopt this technology, they can improve the overall level of mold manufacturing in China.


4.pre-hardening technology


  In the manufacturing process of the mold, heat treatment is a process that most molds use for a long time. Since the 1970s, the idea of pre-hardening has been proposed internationally. However, due to the rigidity of the machine tool and the constraints of the cutting tool, the hardness of the pre-hardening cannot reach the hardness of the mold. Therefore, the research and development of the pre-hardening technology is not large.


  With the improvement of the performance of machine tools and cutting tools, the development of pre-hardening technology for mold materials has accelerated. By the 1980s, the proportion of pre-hardened modules used in plastic molds in industrialized countries in the world has reached 30% (currently In more than 60%), China began to use pre-hardened modules (mainly imported products) in the mid-to-late 1990s.


   Pre-hardening technology for mold materials is mainly developed and implemented by mold material manufacturers. By adjusting the chemical composition of the steel and equipped with the corresponding heat treatment equipment, it is possible to mass produce pre-hardened modules of stable quality. In China, the pre-hardening technology of mold materials started late and has a small scale. At present, it cannot meet the requirements of domestic mold manufacturing.


   The use of pre-hardened mold materials can simplify the mold manufacturing process, shorten the manufacturing cycle of the mold, and improve the manufacturing precision of the mold. It is foreseeable that as processing technology advances, pre-hardened mold materials will be used for more mold types.
