Multi-tooth strip,Carbide mold customized products, Custom shaped products
Introduction of Tungsten Steel Alloy Mould Process:
1. The tungsten steel round bar and other custom shaped products adopts low-pressure sintering technology, and the quality is stable and reliable: The high sintering pressure can reach 100 kg force, and the internal pores of the carbides can be effectively eliminated, so as to obtain a high-hardness and high-strength blank with good densification. The advanced temperature control system can Effectively reduce quality fluctuations.
2. With automatic pressure relief extrusion equipment, various types of bars can be produced.
3. Fine-grind the bar material to achieve the mirror effect: the use of CNC grinder can quickly remove the damage layer generated during polishing, improve the surface finish, and achieve the mirror effect. Precision grinding bar material: diameter tolerance D≤±0.03 length tolerance L≤±0.5.
Production characteristics of cemented carbide molds:
1. Single piece, multiple production, tungsten steel alloy mold is a long-life special process equipment, each mold can only produce a certain shape, size and precision parts, which determines that the mold production is a single piece, multiple varieties The nature of production.
2. Mould processing is developing towards mechanization, precision and automation
3. The mold production cycle is objectively required to be short. At present, due to the acceleration of the upgrading of new products and market competition, the mold production cycle is objectively required to be shorter and shorter, and the production management, design and process work of the mold should meet the objective requirements.
4. The complete set of tungsten steel alloy mold production. When a certain part requires multiple molds to process, each pair of molds often involves and affects each other. Only the final product is qualified, this set of molds is qualified. Therefore, this feature must be fully considered in the production and planning arrangements.
