Polyurethane Molds in Isostatic Pressing Technology
Isostatic press technology is to use Pascal's principle to place the pressed material sealed in the flexible mold or the solid workpiece with a closed shell in a high-pressure cylinder filled with fluid pressure medium, and use high-pressure equipment to exert a certain pressure on the pressure medium in the cylinder. The pressure is transmitted to the interface of the flexible mold or workpiece equally in all directions through the pressure medium, so that the pressed material or workpiece undergoes a certain volume deformation under the action of isostatic pressure, thereby realizing isostatic pressing. If the material to be compressed is a powdery substance, when the pressure acts equally on the surface of the flexible mold, the powder in the package will be uniformly compressed and densified, and its shape is smaller than and similar to the cavity of the flexible mold.
It is the basis of isostatic pressing technology that the fluid medium transmits pressure equally in all directions, and establishing a non-leakage interface between the pressed material and the pressure medium is the key to isostatic pressing technology.
The isostatic pressing of the dry bag method is to semi-fix the elastic mold, not soaked in the liquid medium, but sealed by the upper and lower pistons. The pressure pump injects the liquid medium between the high-pressure cylinder and the pressurized rubber, and the pressure is transmitted through the liquid and the pressurized rubber to form the green body under pressure. This method can be operated continuously, that is, the upper cover of the mold is opened, the material is loaded, and then the upper cover is closed and pressed for molding. The operation cycle is short, suitable for mass production.
Jiangsu High Industry focuses on the research and production of isostatic pressing moulds, customizes various dry bag and cold isostatic pressing moulds, adapts to different models of various manufacturers at home and abroad, and deeply understands the needs of various industries. Alloy, graphite and other industries provide high-performance isostatic pressing mold rubber sleeves.
Product overview: Isostatic pressing rubber mold is used for the molding of ceramic materials, tungsten and molybdenum materials, graphite materials, refractory materials, and alloy powders. It can be customized according to drawings, and can be designed according to samples.
Product features: The deformation of the elastic mold under the pressure of the liquid medium is transmitted to the powder in the mold. The friction between the powder and the mold wall is small, the blank is uniformly stressed, and the density distribution is uniform, and the pre-pressed blank is encapsulated. In the elastic rubber mold, it is put into the high-pressure cylinder after sealing, and the green body is compressed and formed by liquid transfer.
Product advantages: The design of the mold cover is reasonable to ensure no water leakage, the blank is well formed, and the service life is long, including the fixture for processing the blank, which can be customized! There is a free amount of open steel molds.
We support all kinds of customization, if you need it, please contact us.
