Isostatic pressing forming is one of the forming methods for zirconia ceramics. Isostatic pressing forming is mainly a forming method that utilizes the incompressibility of liquid media and uniform pressure transmission. It can shape complex, large, and slender products that cannot be produced by ordinary methods, and has high forming quality. Do you know what the isostatic pressing process for zirconia ceramics is? Below, the editor will introduce to you:

Isostatic pressing forming process of zirconia ceramics:

1. Powder pretreatment

The isostatic pressing forming process for infertile powder also requires pre-treatment of zirconia ceramic powder, improving the flowability of the powder through granulation process, adding binders and lubricants to reduce the friction inside the powder, improving the bonding strength, and adapting it to the needs of zirconia ceramic forming process

2. Forming process

This includes processes such as loading, pressurization, holding, and unloading. The loading should try to ensure that the zirconia ceramic powder is evenly filled in the mold to avoid the presence of pores; When applying pressure, it should be stable and the pressure speed should be appropriate; Select appropriate pressure and holding time for different zirconia ceramic powders and body shapes; Simultaneously select the appropriate pressure relief speed

3. Forming mold

Isostatic pressing has special requirements for forming molds, including sufficient elasticity and shape retention ability, high tensile and crack resistance, wear resistance, good corrosion resistance, no chemical reaction with the medium, good demolding performance, and so on

In summary, it is the isostatic pressing forming process of zirconia ceramics. The isostatic pressing forming process of zirconia ceramics has strong applicability, especially suitable for experimental research and small-scale production. It can simultaneously press two or more different shapes of parts in a high-pressure cylinder and produce large and complex zirconia ceramic parts, with a short production process and low cost
