 The surface of the mold parts processing technology, it is through the surface coating, surface modification, or composite processing technology, change mould parts surface morphology, chemical composition, organizational structure and stress state, in order to obtain the required surface performance of the system engineering.Nitriding process with gas nitriding, ion nitriding and liquid nitriding, in every way of nitriding, there are several kinds of nitriding technology, can adapt to the requirement of different steel grade artifacts.From surface treatment on the way, and can be divided into: chemical method, physical method, physical and chemical methods and mechanical methods.Although the new designed to improve the surface performance of the mold parts processing technology constantly emerging, but more mainly used in the mould parts manufacturing nitriding and carburizing and hardening film deposition.Because of nitriding technology can form the surface of the excellent properties, and nitriding technology and mould parts of steel quenching process has the good coordination, nitriding temperature is low, at the same time without fierce cooling after nitriding, the mould parts deformation, so the mould parts surface strengthening is earlier by nitriding technology, is also the most widely used.
  Mould parts in addition to the requirements in the work has a high enough strength and toughness, the surface properties of die parts working performance and service life is very important.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 of the mold parts processing technology, often can get twice the result with half the effort, which is surface treatment technology has been developed rapidly.Performance refers to: the surface wear resistance, corrosion resistance, friction coefficient, fatigue performance, etc.
  Mould parts, the purpose of carburizing is mainly in order to improve the mould parts of the overall strong toughness, namely the mould parts of the surface of the work is of high strength and abrasion resistance, this idea is the introduction of technology, with lower material, by carburizing and quenching instead of higher-level material, thereby reducing the manufacturing cost.Hardening film deposition techniques as early as the tool, cutting tool, cutting tool and measuring tool, etc.) on the application of excellent results, a variety of coated cutting tool have hardened membrane as a standard process.Hardening film deposition technology is now more mature of CVD and PVD.In order to increase the bonding strength of the coating surface, now developed a variety of enhanced CVD and PVD technology.
  Mould parts since the 80s the sclerosis of coated membrane technology.Current technology condition, the hardening film deposition techniques (mainly is the cost of the equipment) is higher, is still only in some parts of precision, long life molds on application, if adopt the way of setting up heat treatment center, the coating will greatly reduce the cost of hardening membrane, if more die parts using the surface of the mold parts processing technology, can overall improve the level of mold parts processing in China.
