Powder Metallurgy Cold Isostatic Pressing Bags
Powder metallurgy is the processing method of making metal powder and forming and sintering process to make metal powder or the mixture of non-metal powder into products. It can not only make special materials which are difficult to make by ordinary melting method, but also make various precision mechanical parts, saving labor and materials. But its mold and metal powder cost is high, batch size or product size is too large should not be used. Compared with traditional materials and processes, powder metallurgy materials and processes have the following characteristics:
1. Powder metallurgy process is lower than the matrix metal melting point, so can obtain a variety of metal melting point, density difference, metal and ceramic, metal and plastic and other heterogeneous special functional composite materials and products.
2. Improve material properties. The fine metal or alloy powder prepared by special method has very fast solidification speed and fine and even grain, which ensures the uniform structure of the material, stable performance, and good cold and hot working performance, and the powder particles are not limited by the alloying elements and content, which can improve the content of the strengthening phase, so as to develop a new material system.
3. Using a variety of forming processes, the powder raw materials can be directly formed into less spare, no spare blank or net shape parts, greatly reducing the amount of machining. Improve material utilization and reduce costs.
Cold isostatic pressing
That is, at room temperature static pressing, liquid as the pressure transfer medium. The powder body into the elastic mold, placed in the steel body sealed container, with a high pressure pump to press the liquid into the container, using the liquid uniform transfer of pressure characteristics, so that the powder body in the elastic mold uniform pressure. Therefore, the cold isostatic pressing billet has high density, uniform, good mechanical properties, large size and complex shape, and has been used in the production of bars, pipes and large-scale products.
Jiangsu High Industry on the research and development and production of high-performance polyurethane isostatic pressing molds. Through in-depth cooperation with many isostatic pressing equipment manufacturers and in-depth study of the industry, the developed isostatic pressing polyurethane mold series products have the characteristics of long service life, high precision, small deformation, easy demoulding, etc., and are widely used in ceramics, etc. Static pressing mould, cemented carbide isostatic pressing mould, rare earth permanent magnet material isostatic pressing mould, graphite isostatic pressing mould, etc.
