Isostatic pressing is to place the sample to be pressed in a high-pressure container, and use the incompressible properties of the medium and the properties of uniform pressure transmission to uniformly pressurize the sample from all directions. When the medium is injected into the pressure vessel through the pressure pump, according to The principle of fluid mechanics, the pressure is constant and uniformly transmitted in all directions. At this time, the pressure on the powder in the high-pressure container is uniform and consistent in all directions. Features: During isostatic pressing, the pressure transmitted by the medium is equal in all directions. The deformation of the elastic mold when it is under the pressure of the medium is transmitted to the powder in the mold. The friction between the powder and the mold wall is small, the green body is evenly stressed, the density distribution is uniform, and the product performance is greatly improved. According to the forming temperature, isostatic pressing technology is usually divided into cold isostatic pressing, warm isostatic pressing and hot isostatic pressing.
Cold isostatic pressing is divided into two types: dry bag isostatic pressing and wet bag isostatic pressing.
Dry bag isostatic pressing is to permanently fix the forming mold (cover) in the high-pressure cylinder, and directly fill the powder into the package in the high-pressure cylinder for pressing. The feature is that it is suitable for mass production of simple shape parts and is easy to automate.
The jacket used for wet bag isostatic pressing is not a fixed part of the high-pressure cylinder, and the jacket is completely immersed in the liquid medium. It is characterized by strong adaptability, can have multiple bags in one tank at the same time, is suitable for small batch production, and can produce large and complex parts.
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.
