Isostatic Pressing Molds for Industry Ceramic

Isostatic Pressing Molds for Industry Ceramic

With the continuous development and progress of science and technology, an industrial ceramic with superior properties such as high temperature resistance, corrosion resistance, wear resistance, and erosion resistance has been widely used in various fields. Next, I will introduce the isostatic pressing of industrial ceramics. There are two types of isostatic pressing for industrial ceramics: cold isostatic pressing and hot isostatic pressing. Cold isostatic pressing is divided into wet isostatic pressing and dry isostatic pressing.

The process can be summarized as filling the rubber sleeve with the applicable product size with the powder first, and then placing the rubber sleeve in a high-pressure container, using the incompressible properties of the liquid medium and the properties of uniform pressure transmission to uniformly pressurize the rubber sleeve from all directions. The pressure is about 200 tons. When the liquid medium is injected into the pressure vessel through the pressure pump, according to the principle of fluid mechanics, its pressure is constant and uniformly transmitted to all directions. At this time, the powder in the high-pressure vessel is under pressure in all directions. are uniform and consistent in size.

Features of isostatic pressing of industrial ceramics 

1. It can form simple, large, thin and long products that cannot be produced by general methods, and the forming quality is high.

2. It is convenient to increase the molding pressure without increasing the difficulty of operation, and the pressure effect is better than other dry pressing methods.

3. Because the green body is under uniform pressure in all directions, its density is high and uniform, and its firing shrinkage is small, so it is not easy to deform.

4. The mold is easy to make, has a long service life and low cost.

5. Less or no binder can be used.
