Hydraulic powder metallurgy forming process

Forming is an important step in the powder metallurgy process. The purpose of forming is to produce a compact with a certain shape, size, density and strength. Powder compression molding is the most basic molding method.

Powder metallurgy compression molding process

The powder molding method has a simple process, high efficiency, and is convenient for automated production. However, the pressure distribution of this method is not uniform, so that the density of the green body is not uniform, and cracking is prone to occur, leading to the appearance of defective products.
