The Advantages of Polyurethane Isostatic Pressing Mold
Polyurethane isostatic pressing mold is used for wet bag isostatic press or dry bag isostatic press as a soft mold for transmitting pressure, also known as sheath. It is a soft mold obtained by enlarging the size of the green body in proportion, but it is relatively hard and has a certain support strength to set the shape. It can be filled with powder or packed into a preformed green body, sealed and put into a liquid for isostatic pressing. Also known as wet bag isostatic pressing. It can also be made into a suitable size polyurethane isostatic pressing mold for dry bag isostatic pressing.
Advantages of polyurethane mold
1. Accuracy
Materials made by using isostatic pressing molds can often be applied in important occasions, or used in related precision equipment, so the accuracy requirements are relatively high. If the accuracy of the mold is not enough , It will also lead to excessive processing, and even deformation, including whether the compression rate in all directions can be kept consistent after the mold is under pressure, and whether the original precision can be maintained after continuous use. It will also affect the quality of product molding.
2. Ease of use
The characteristics of the isostatic pressing mold also determine whether it can meet the different processes, whether other auxiliary fixtures can be minimized during use, including whether it is easy to demould after use, and whether it can rebound quickly. will have a certain impact on its operation.
3. Pressure resistance
Because isostatic pressing molds can work in high-pressure environments, and also need to be in contact with oil and other media, if the pressure resistance is not good enough, or the chemical resistance is not good, then the performance The upper part is easy to drop, so it is necessary to understand this characteristic, and it will also affect the subsequent process.
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.
