Cold Isostatic Pressing
The cold isostatic press technology is a new type of powder forming and pre-pressing technology developed according to Pascal's principle. Pascal's basic principle is also called the basic principle of negative pressure transmission. Its specific content is that the gas pressure added to the closed liquid state can be transmitted from the liquid state to different directions without changing its size. Isostatic pressing technology was first developed by the Westinghouse Light Bulb Company in the United States in 1913. Then, isostatic pressing technology and application scale developed rapidly, and now it has been widely used in industries such as casting, nuclear energy, plastics, high-purity graphite, ceramics, permanent magnets, microbial drug production, food refrigeration, and military use.
Cold isostatic pressing usually seals the powder in a soft sheath, and then puts it into a liquid medium in a high-pressure container. By applying pressure to the liquid, the powder is uniformly pressed in all directions, so as to obtain the required compact. The liquid medium can be oil, water or glycerin. The sheath material is an elastic-plastic material such as rubber. Metal powder can be directly loaded or molded to fit the sleeve. Because the powder is uniformly pressed in all directions in the sheath, a compact with a relatively uniform density can be obtained, so it is not easy to deform and crack during sintering. The disadvantage is that the dimensional accuracy of the compact is poor, and machining is required. Cold isostatic pressing has been widely used in the forming of cemented carbide, refractory metals and various other powder materials.
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.
