Explanation

A method of unformed powder refers to that the loose powder undergoes certain jacking pressure in the mold to become a compact with certain size, shape, density and strength. When the pressure is applied to the powder in the die, the powder particle will move relatively, powder particle will fill the pores, reducing the volume of powder, and powder particle will quickly reach the most compact accumulation. pressing is a very complicated process. The key to the ability of powder to form in is the characteristics of the powder itself. Among the various elements that affect the process, pressure plays a decisive role. There are five basic methods: unidirectional, bidirectional, floating, pull-down, and friction core rod.
