Molds are various molds and hand basin mould used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die-casting or forging molding, smelting, stamping and other methods. The mold mainly realizes the shape of the article by changing the physical state of the molded material Processing.
The steel required for molds can be divided into three types: cold work die steel, hot work die steel and plastic die steel. Zhisheng Weihua mold anti-corrosion coating personnel summarized that cold molds are used for forging, stamping, cutting, die-casting, etc. Cold work molds include cold punching dies, wire drawing dies, drawing dies, stamping dies, thread rolling dies, rolling plates, and cold heading Die and cold extrusion die, etc.; hot work die is divided into hammer forging, die forging, extrusion and die casting, including hot forging die, press forging die, stamping die, hot extrusion die and metal die casting die, etc. . Plastic molds include thermoplastic molds and thermoset plastic molds. Plastic mold steel requires certain strength, hardness, wear resistance, thermal stability and corrosion resistance.
Comprehensively, the protection of steel under high temperature of the mold is the key, and it is particularly important to do a good job of high temperature anticorrosive coating of the mold. Located in Fengtai District, has recently developed two mold high-temperature anticorrosive coatings, ZS-722 thermally conductive anticorrosive coating and ZS-822 composite ceramic high temperature anticorrosive coating, which are developed and produced according to the actual working conditions of the mold, with high temperature resistance and wear resistance. Impact resistance, acid and alkali corrosion resistance. Brushed on high temperature molds for corrosion and wear resistance.
The long-term temperature resistance of ZS-722 acid-resistant thermally conductive anticorrosive coating can reach 750℃, the coating conductivity (70℃) can reach 50w/mk, and the coating blackbody thermal radiation coefficient can reach 0.92;, the heat exchange rate can be increased by more than 10 compared with the base material of the ZS-722 acid-resistant, thermally conductive and anticorrosive coating without ZS-722
