Press Forming of ceramic powders is a specific forming technique for ceramics. It is a process in which ceramic granular materials are made cohesive through mechanical densification, involving (hot pressing) or not (cold forming) temperature exposition. The process permits an efficient production of parts ranging widely in size and shape to close tolerances with low drying shrinkage. Traditional (for instance: ceramic tiles, porcelain products) and structural (for instance: chip carriers, spark plugs, cutting tools) ceramics are produced. Cold compaction of ceramic powders ends up with the realization of the so-called green piece, which is later subject to sintering.
