Isostatic Pressing Molds for Isostatic Graphite

Isostatic Pressing Molds for Isostatic Graphite

Isostatic graphite molding

Different from ordinary extrusion molding and compression molding, isostatic graphite is formed by cold isostatic pressing technology. Fill the raw material compressed powder into the rubber mold, and make the compressed powder dense through high-frequency electromagnetic vibration, vacuumize after sealing, discharge the air between the powder particles, and put it into a high-pressure container filled with liquid media such as water or oil. Pressurize to 100-200MPa, press into cylindrical or rectangular products.

According to Pascal's principle, the pressure is applied to the rubber mold through liquid medium such as water, and the pressure in all directions is equal. In this way, the pressed powder particles are not oriented in the filling direction in the mold, but are compressed in an irregular arrangement. Therefore, although graphite is anisotropic in crystallographic properties, as a whole, isostatic graphite But isotropic. In addition to cylinders and rectangles, the formed products also have shapes such as cylinders and crucibles.

The isostatic pressing machine is mainly used in the powder metallurgy industry. Due to the needs of high-end industries such as aerospace, nuclear industry, cemented carbide, and high-voltage electromagnetics, isostatic pressing technology has developed very fast, and has the ability to manufacture cold isostatic pressing machines with a working cylinder inner diameter of 3000mm, a height of 5000mm, and a maximum working pressure of 600MPa. At present, the maximum size of the cold isostatic press used in the carbon industry to produce isostatic graphite is Φ2150mm×4700mm, and the maximum working pressure is 180MPa.

    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.
