Sintered products formed by powder and strengthened by sintering.
Parts usually have precise tolerances and are easy to install. Material powder mixtures also contain lubricants to reduce the friction produced during compaction.
Powder mixtures are the initial materials for manufacturing sintered parts. The base powder can be pure iron, low alloy steel, stainless steel or high speed steel. The performance of the final part can be adjusted by using additives such as carbon, alloy elements and cutting enhancers. Powder mixtures also contain lubricants to reduce the friction produced during compaction.
The most common method of pressing is axial pressing in steel or cemented carbide dies. Mechanical presses or hydraulic presses can generate 400-800 MPa of demand pressure. Complex shape parts can be pressed under one-step operation procedure, and the productivity is high, up to 25 parts per minute. After pressing, the parts can reach the predetermined shape and density. But this is not its final size or strength.
