DESCRIPTION

Isostatic Pressing Process

Isostatic pressing refers to cold isostatic pressing, which can be divided into two forms according to the different forming processes: wet bag type and dry bag type.

The wet bag isostatic pressing technology is to put the granulated ceramic powder or pre-formed body into a deformable rubber casing, and then apply uniform pressure in all directions through the liquid. The rubber cover is removed from the container, which is a discontinuous molding method. The advantages of this technology are that the cost is relatively low, the flexibility of forming products of different shapes is large, and the pressure can reach 500MPa. This technology can be used in the laboratory and in a certain scale of production, and can form parts of moderate complexity. The disadvantage is that the number of products formed in a certain period of time is small.

Dry bag isostatic pressing (dry bag isostatic pressing) molding technology is to fill ceramic powder into flexible pre-formed molds in batches, and then apply isostatic pressing. Since the mold is fixed in the equipment, the molded product is ejected after pressing. The "dry bag" type has a short molding cycle and a long service life of the mold, which is especially convenient for large-scale continuous industrial production. The mold materials used are polyurethane synthetic rubber or silicone rubber. Compared with wet bag isostatic pressing, the dry hair isostatic pressing pressure is lower, generally within 200 MPa. The most familiar ceramic spark plugs are currently formed by dry bag isostatic pressing, and the pressing time is usually only 1~2 s.

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.
