Introduction to Zirconia Ceramic Steel Mold Pressing and Forming

The pressing method of zirconia ceramic steel mold is the most commonly used forming method. Because of the friction between zirconia ceramic powder particles, powder and die punch, die wall, the pressing pressure is lost, resulting in uneven density distribution of the compact. When zirconia ceramics are pressed unidirectionally, the density decreases along the height direction.

In order to improve the density distribution of zirconia ceramics compacts, on the one hand, it can be changed to two-way pressing (including floating female mold), on the other hand, it can be mixed with lubricants such as oleic acid, Zinc stearate, Magnesium stearate, paraffin gasoline solution, etc.

The pressing pressure of zirconia ceramic materials is generally 40-100MPa. Molded forming is generally suitable for zirconia ceramic products with simple shapes and small sizes. With the improvement of die design and press automation, some complex shaped zirconia ceramic parts can also be produced using pressing methods. Zirconia ceramic steel mold pressing is easy to achieve automation.
