Mold Surface Treatment Technology Development

Small deformation, can be used in pressure-chou mold, cold extrusion die and plastic mold, respectively, and increased life expectancy I ~ 9 times. Recently Yu nitrocarburizing salt cured with new developments such as new technology TFI4-AB1 salt bath carbonitriding in the Department of oxidative alkaline bath after immersion, the surface oxidation treatment, black, after this treatment life expectancy greater than or equal to casting mold gas nitrocarburizing of the mold. This process materials in the process, the atmosphere control, seepage and unstable thickness and organizations there are still problems. ③ ammonia pollution of sulfur and the carbon composite alloying treatment: the development of this process is called in France Sttrs, xl ~. Feature is the amount of cyanide ancient molten salt does not exceed 0.8, the S, N, C into the workpiece surface so that the enhancement is a patented cross with industry by 1991. No. Total 1119 bundles. Wuhan material security by the LT! New technology has also reached the same level of French technology. France has developed in recent Carbon nitride after carbonitriding treatment Oxynit process, the domestic development of the LTc a 1, LTc-2 technology for a variety of molds are good strengthening effect. 3. A leopard cross the manufacture of thermal spray technology for spraying heat sources are: the gas flame, arc, plasma arc,[link widoczny dla zalogowanych], energy, etc., spray material can be wire, bar or powder beam. Used in the mold repair is also very effective. Development is an energy of (80kW high energy plasma spray equipment), automated. Composite coating materials to develop ultra-fine powder. Italian low-temperature metal spray gun with MCP guillotine for mold. Abroad are used flame spray a little nickel-based self-fluxing glass mold making and repair, life expectancy doubled. Plastic extrusion die has 40WC Flame Spraying of nickel-based self-fluxing coating units stacked, thick 1mii1, life expectancy increased by 1 times. l Many mold sprayed WC + Co base stations are all starting from the Life of a mention. 4. Plating technology in mold manufacturing, casting 4.1 hard drive is mainly used for processing complex cavity of the mold. Material security of the Wuhan Institute of rubidium electroforming technology close to advanced Chengping, in particular, stress test systems, and electroforming Shu Tian additives. 4.2 Ni-P Taijin widespread rejection of foreign technology of electroless nickel plating the life of pricey plastic mold and consolidated platform performance. This process has the advantage of low processing temperature, for 85 ~ 95 4.3, also known as spread-plated composite coating or dispersion coating, metal plating solution is added to non-metallic particles, stirring to evenly suspended in the metal electrodeposition at the same time, non-metallic particles were also re-pad in the base wall of Mi Ken Mexican coke history of rhino Da l § obstruct favorite exercise discretion in grinding and so on. Usually Ni,[link widoczny dla zalogowanych], cr _ plating adding transition wear such as oxides or carbides, such as Recovering material A1, Os,[link widoczny dla zalogowanych], diamonds and so on. Electroless nickel and PTFE (polymer) composite plating process has been successfully developed applications. 4. Brush with the retirement of the mold die and suffer large complex on the sense. Brush plating technology company is Dal'c new development process is simple and flexible. Wuhan material security interest of the developed 6 bath, coating subtle light, good wear resistance. 5 EDM Die surface infiltration surface infiltration techniques Crl2 thickness 5 ~ 20gm of WC cemented carbide, HRC70 --- '72, life expectancy increased by 2 to 3 times. This method to strengthen the Soviet mold, life expectancy increased by 1 to 3 times. 6 Conclusion In order to change the few varieties of mold, feature poor, low precision and disadvantages of short life, strong well established surface treatment technologies, should be accorded the necessary attention. Surface treatment technology has a lot of research and Cheng Gao extended to future production should be large virtual set to use in this policy should be to the l; c ensure that the mold without surface treatment factory, etc. are not allowed. It should also further develop research and development of new technology, such as in large, dense sugar mold to carry out PVD, vacuum plasma technology, the application of circular braided treatment. Surface coating technology, electroforming, electroless plating, plating and other units should be vigorously re-development application. Some edge technologies, such as plating a penetration, spray penetration should continue to develop an improved and applications. In general, CVD method TiC,[link widoczny dla zalogowanych], boron penetration can be used for such cold-working die Die, infiltration and c-B Cr alloying can be used for hot die forging, etc.} ion nitriding, carbonitriding sulfur ammonia can be used for die-casting mold , plastic mold and so on. Surface treatment technology in research to improve the die life, it should also solve the mold with slip Lan Jing problem. (Journal of boxing has abridged) die design and manufacture of automotive training course that the Chinese die and mold equipment, Auto Body Association Committee on Education and Training Committee and the second car factory out of the police station module plant associated blocking Rb-run classes in this fluttering of flag l1 months 24B the end of study time zO days, students participate in more than 4O. (Wang Liwei reported) plow is an industrial 1991. No. 1 HI 119l3
