Polyurethane Isostatic Pressing Bags
In isostatic pressing, the prototype that needs to be pressed is placed in a high-pressure container, and the pressure is evenly transmitted through the liquid pressure transmission medium, and various pieces are pressurized from all directions, so that the workpiece is formed to achieve the desired effect. In this pressing process, the workpiece needs to be isolated from the pressure transmission medium, and cannot be in contact with the pressure transmission medium (hydraulic oil) to cause mutual contamination. This requires an isostatic die (rubber sleeve) capable of hydraulic work.
Commonly used isostatic pressing molds include polyurethane isostatic pressing molds and rubber isostatic pressing molds. In traditional isostatic pressing equipment, rubber is widely used due to its early application in isostatic pressing molds. However, in recent years, polyurethane has gradually become known to people. Because of its excellent elasticity, it is replacing rubber products in various industries at an alarming rate, including isostatic rubber molds in isostatic pressing equipment.
The polyurethane isostatic pressing mold specially customized according to the requirements of isostatic pressing has the advantages of other materials, but overcomes the shortcomings of other materials. It is an ideal material for isostatic pressing: widely used dry bag isostatic Pressing equipment and mixed isostatic pressing equipment; dry cemented carbide; ceramics: stone black and other materials: excellent use effect. High resilience, anti-fatigue, low deformation rate, easy mold release, used in dry bag and wet isostatic presses to press ceramic product blanks, graphite products, hard alloys and other non-standard powder molding.
The forming precision is high and the surface is smooth. The surface of the mold itself is very smooth and dense, and the pressed product has a smooth surface, beautiful appearance, less post-processing and cost saving.
The mold itself is easy to shape, and the cost is low and the efficiency is high when making the mold for special-shaped parts. Before the polymer material is made into a mold, it is in a liquid state and can be made into molds of various shapes. The cost of mold opening is low and the production cycle is short. The mold has good resilience, low deformation, aging resistance, long service life, and reduces production and use costs. The anti-oxidation and anti-aging capabilities of polymer materials are significantly stronger than traditional isostatic rubber molds, and they will not deform after continuous use, and will not age and become sticky like rubber. Oil-resistant, chemical-resistant, wide range of use, can be applied to a variety of working conditions.
