“Pressing ceramics” means that granular or powdery materials are pressed under pressure to form a solid body with a geometrical defined shape. The required pressure is generated isostatically or axially using a hydraulic press. After the pressing operation, the green body (the in shape pressed ceramic part) has to be treated in various post-processing systems until it has reached its final state.<\/p>\n

The next machining step is the sintering process: The green body is placed in a sintering furnace and fired at very high temperatures. This increases the density and strength of the pressed part, during the porosity and volume of the green part is reduced.<\/p>\n

 <\/p>\n

If the sintered part should have a very high dimensional accuracy, the workpiece is post-treated in a sizing press. In this step the workpiece is compressed again with axially generated pressure, so that the most exact position and shape tolerances can be reached.<\/p>\n
