High Quality Alumina AL2O3 Ceramic
Molding method of Alumina AL2O3 Ceramic:
- Dry press molding is a common technique used in the creation of product.
The dry pressing technology of alumina ceramics is limited to objects with a simple shape, an inner wall thickness of more than 1mm, and a length to diameter ratio of no more than 4:1.
They formed this way have single axial or bidirectional methods. Additionally, the press has two types: hydraulic type and mechanical type, which can be semi-automatic or fully automatic forming mode. It has a maximum pressure of 200Mpa, and the output can reach 15~50 pieces per minute.
Due to the uniform stroke pressure of the hydraulic press, the height of the pressed parts made from Alumina AL2O3 Ceramic might vary when the powder filling is different. Additionally, products often use al2o3 ceramic materials in complex designs. Furthermore, the pressure applied by the mechanical press changes depending on the amount of powder filling. This variability leads to differences in size shrinkage after sintering, ultimately affecting product quality.
- Grouting molding method enhances the production method for products made from Alumina AL2O3 Ceramic.
Grouting molding is the earliest molding method used in the manufacturing of alumina ceramics. When employing this technique for Alumina AL2O3 Ceramic production, due to the use of gypsum mold, it is low cost and easy to form large-size, complex components.
When the mold wall adsorption slurry reaches the required thickness, pour out the excess slurry. In order to reduce the shrinkage of products involving alumina ceramics, one should try to use high concentration slurry. Welcome inquiry.
