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.
According to Pascal's principle, it is used for the molding of various powder products under ultra-high pressure. The working principle of isostatic pressing is Pascal's law: "The pressure of the medium (liquid or gas) in a closed container can be transmitted equally in all directions.
An isostatic press is a molding equipment that operates under high pressure. Isostatic pressing is to place the object to be processed in a specific mold, and then put the mold containing the workpiece into a closed container full of liquid, and gradually pressurize it through the pressurization system, and transmit the pressure through the liquid, so that the Each surface of the object is subjected to equal static pressure, product varieties: ceramic plunger, ceramic pump core, ceramic valve core, ceramic piston, ceramic bushing, ceramic suction cup, microporous ceramics, etc.; materials: alumina, zirconia, Silicon nitride, silicon carbide. And the process of forming under the constraints of the mold.
