Alumina seramik tupela narapela narapela rot bilong wokim
The forming methods of alumina ceramic products include dry pressing, grouting, extrusion, cold isostatic pressing, injection, casting, hot pressing and hot isostatic pressing. In recent years, at home and abroad have developed a filter molding, direct solidification injection molding, gel injection molding, centrifugal injection molding and solid free molding technology.

1, dry press molding: alumina ceramic dry press molding technology is limited to simple shape and inner wall thickness of more than 1mm, length and diameter ratio is not greater than 4:1 objects. The molding methods are uniaxial or bidirectional. The press has two kinds of hydraulic type and mechanical type, which can be semi-automatic or automatic forming method.

Therefore, the uniform distribution of powder particles in the dry pressing process is very important for mold filling. Whether the filling amount is accurate or not has a great influence on the dimensional accuracy control of manufactured alumina ceramic parts. Powder particles with more than 60μm, between 60 ~ 200 mesh can obtain the maximum free flow effect, to achieve the best pressure molding efek.
