High precision non-standard mold parts are not only required to have high strength and toughness in the work, but their surface performance is crucial to the performance and service life of high precision non-standard mould parts.The improvement of the performance, to improve and improve of relying on a substrate material is very limited, also not economic, and through the surface processing technology, often can get twice the result with half the effort, which is surface treatment technology has been developed rapidly.Mould polishing technology is an important part of mould surface engineering and is an important process in the process of die manufacturing.Due to domestic polishing technology and materials, etc, also there are some problems, so as a camera lens, CD, VCD discs of injection moulds and tools require high transparency of injection mold are still largely dependent on imports.

What are the characteristics of high precision non-standard mould parts?

Mirror mould material is not only chemical composition problem, more major is require the use of vacuum degassing, argon gas protection when smelting ingot casting, vertical continuous casting and rolling, forging and a series of advanced technology, make the mirror steel with less internal defects, fine granularity, high degree of dispersion, metal impurities of fine grain size and uniformity is good wait for a series of advantages, polished to a mirror in order to achieve the requirement of steel.Die parts surface treatment technology, it is through the surface coating, surface modification, or composite processing technology, change the high precision mold parts surface morphology, chemical composition, organizational structure and stress state, in order to obtain the required surface performance of the system engineering.The nitrification process has gas nitrification, ion nitriding, liquid nitriding and other methods. In each case, there are several kinds of nitrizing technology, which can be used to meet the requirements of different types of steel.The methods of surface treatment can be divided into: chemical methods, physical methods, physical chemistry methods and mechanical methods.

It is important to note that the mold surface polishing not only affected by polishing equipment and process technology, also affected by the mold material mirror degrees, this has not caused enough attention, that is to say, polishing the restriction of the die material itself.Although designed to improve the surface performance of the precision mold fittings new technology constantly emerging, but the application in high precision non-standard mold parts manufacturing more mainly nitriding and carburizing and hardening film deposition.Because of nitriding technology can form the surface of the excellent properties, and nitriding process and high precision non-standard mold parts of steel quenching process has the good coordination, nitriding temperature is low, at the same time without fierce cooling after nitriding, the high precision non-standard mold parts deformation, thus high precision non-standard mold parts surface strengthening is earlier by nitriding technology, is also the most widely used.
