Isostatic Powder Compacting
Isostatic powder compacting is a mass-conserving shaping process. Fine metal particles are placed into a flexible mould and then high gas or fluid pressure is applied to the mould. The resulting article is then sintered in a furnace. This increases the strength of the part by bonding the metal particles. This manufacturing process produces very little scrap metal and can be used to make many different shapes.
The isostatic pressing method has two types: cold isostatic pressing and hot isostatic pressing.
Cold isostatic pressing is further divided into wet isostatic pressing and dry isostatic pressing. The mold is in a high-pressure liquid and the parties are pressed, so it is called wet isostatic pressing. It is mainly suitable for molding multi-variety, complex shape, small output and large-scale products.
Isostatic molding is a pressing process for densifying a powdered composition into a compact shape at pressures sufficient to obtain near theoretical density. Powder and particulate matter is densified under pressure acting through a suitable fluid medium preferably a liquid to achieve an omnidirectional high green density.
