What is the powder metallurgy forming method?

Powder metallurgy forming is divided into powder metallurgy stamping forming and powder metallurgy special forming. Powder metallurgy forming is a process to densify metal powder into a matrix with certain shape, size, density and strength. This is one of the basic processes of powder metallurgy technology.

Generally, metal powder is pretreated before powder forming to meet the requirements of forming. When mixing, a certain amount of powder forming additive shall be added. Powder compaction, also known as powder compaction, is an early forming method used in powder metallurgy production. At the end of the 18th century and the beginning of the 19th century, Russia and Britain used steel molds to make platinum products.

Thereafter, the powder stamping forming method was gradually improved, stamping various kinds of oil bearing, powder metallurgy antifriction products, powder) fund mechanical structural parts and other pressured powders. Since the 1930s, powder stamping has further developed and improved in stamping and mold design. Parts with complex shapes can be stamped with higher mechanization and automation.

Special powder forming is used in the case of special requirements for the shape, size and density of billets. One after another, there are powder cold pressing, powder rolling, powder extrusion, slurry pouring and powder explosive forming. Powder injection molding appeared in the 1970s, and metal powder injection molding appeared in the 1980s. Powder injection molding has developed rapidly in the United States and Japan, and can produce high-precision, irregular shaped products and thin-walled parts.
