Way of forming alumina ceramic wear

First to introduce the next two relatively common molding method.
     1, dry pressing: alumina ceramic dry pressing technology is limited to simple shapes and wall thickness exceeding 1 mm in length and diameter ratio greater than 4:1 is not an object. Forming methods are uniaxial or bi-directional. The size of mechanical presses for powder filling pressure changes by how much, easily lead to shrinkage after sintering size differences affect product quality. Therefore, the process of dry-pressed powder particles uniformly distributed on the mold filling is very important.http://www.prmindustry.com/
Abstract...Articles section      2, the slip casting method: alumina ceramic slip casting is formed using the first method. The key is the slip casting alumina slurry preparation. Flux medium is usually water, then add the solution of glue and binder, full exhaust after grinding, and then poured into the plaster mold. Alumina ceramic slurry by adding organic additives needed to make the slurry particle electric double layer formed on the surface so that no precipitate slurry stable suspension.

     Alumina ceramic forming methods There are many, like extrusion, cold isostatic pressing and so on, at home and abroad in recent years has developed a filter press molding, injection molding directly solidified, gel molding, centrifugal slip casting and solid free forming methods such as molding technology.
