What pre-treatment is required before powder metallurgy forming

MIM combines the advantages of powder metallurgy and plastic injection molding, breaking through the limitations of traditional metal powder compression molding processes in product shape. MIM can sinter dense Machine element with good mechanical properties and surface quality by using powder metallurgy technology. At the same time, the use of plastic injection molding technology can produce many parts with complex assembly features in large quantities and high efficiency, such as various external grooves, external threads, crime external surfaces, cross through holes, blind holes, concave and key pins, reinforcing ribs, surface knurling, etc. Parts with these features cannot be obtained using conventional powder metallurgy methods, precision casting, and other processes.

Powder metallurgy has unique chemical composition and mechanical and physical properties that cannot be obtained using traditional casting methods. The use of powder metallurgy technology can directly produce porous, semi dense, or fully dense materials and products, such as oil-bearing bearings, gears, cams, guide rods, cutting tools, etc., which is a rare and non cutting process. Applied to automobiles, motorcycles, textile machinery, industrial sewing machines, electric tools, and hardware tools. Electrical appliances, construction machinery, etc. Powder metallurgy is a process technology that produces metal powder and uses forming and sintering processes to make metal powder into materials and products. It is a branch of metallurgy and materials science.
