The production of bulk materials and parts using aluminum alloy powder as raw material through molding and solidification began nearly 100 years ago, until General Motors first adopted the press sintering process to produce engine bearing cover parts in 1992, marking the beginning of the large-scale production stage of aluminum alloy powder metallurgy. This production process includes powder mixing, mold pressing and forming, sintering, and post-treatment, with commonly used equipment being mechanical presses or hydraulic presses, Vacuum or mesh belt sintering furnace. At present, MPP and GKN companies produce 30 million various types of bearing cover parts every year. In recent years, domestic companies such as Ningbo Dongmu and Jiangxi Tianqi have also started using the pressing and sintering process to produce aluminum alloy parts.
