ISO Bags for Isostatic Pressing Technology

The pressure directly acts on the powder body or the elastic die sleeve, so that the powder body is balanced in all directions at the same time to obtain a uniform density distribution and high strength of the compact process, according to its characteristics are divided into cold isostatic pressing and hot isostatic pressing two categories.

(1) Cold isostatic pressing

That is, isostatic pressing at room temperature, and liquid is the pressure transmission medium. The powder body is loaded into the elastic mold, placed in the dry steel body sealed container, the liquid is pressed into the container with high pressure pump, and the liquid evenly transfer pressure characteristics, so that the powder body in the elastic mold uniform pressure. Therefore, cold isostatic pressing breaks the density of high, comparative field

Uniform, good mechanical properties, large size and complex shape, has been used in the production of bars, pipes and large products.

(2) Hot isostatic pressing

The powder body crushed or loaded into a special container is placed in a hot isostatic press high-pressure container, high temperature and high pressure, so that these powder bodies are pressed and burned into dense parts or materials, the process of static pressing at high temperature can activate the phenomenon of diffusion and waist change, promote the atomic diffusion and re-bonding of the powder and plastic deformation at a very slow rate. Gas is the medium of pressure transfer. The powder body is subjected to the joint action of high temperature and high pressure in the isostatic pressure container at the same time, which strengthens the pressing and sintering process, the pressing pressure and sintering temperature of the product are lower than that of the cold isostatic pressing, the density and strength of the product are high, and the uniformity is uniform, the grain is small, the mechanical properties are high, the defects and pores between the particles inside the material are eliminated, and the shape and size are not limited. Hot isostatic pressing has been used in the production of powder high speed steel, refractory metal, superalloy and cermet.

    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.
