Isostatic Pressing Molds for Isostatic Pressing Technology

Isostatic Pressing Molds for Isostatic Pressing Technology

Isostatic pressing is a kind of molding method for silicon carbide products, and reaction-sintered silicon carbide can also be formed by isostatic pressing.

Reactive sintering is the addition of excess carbon in the billet, the use of capillary action in the sintering process penetration, the finished product can be regarded as large and small silicon carbide blocks bonded together through silicon. Isostatic pressing is a special way of pressing forming. The principle of liquid pressure transfer is used to press the blank from all directions to improve the density of the blank body, so that the density of the blank body is increased, which can effectively reduce the sintering shrinkage, reduce or even eliminate the problem of sintering cracking deformation, and also effectively improve the density of sintered finished products.

There is a positive correlation between the density of blank and the density of finished product. The density of the finished product is the basis of its good mechanical properties. Compared with traditional molding, isostatic pressing production efficiency and cost are relatively inferior, but the quality is superior, and soft molds such as rubber molds for isostatic pressing have their own scope of application compared with traditional molding steel molds.

    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.
