Manufacture and Properties of P/M Bearing Caps

P/M main bearing caps are important structure parts in automotive engines. They have special shape and high precision and endure complicated load in using. After analysis the structure and property characteristics, we use Fe-C-Cu-Ni material, double-action-floating-pressing technology, liquid-phase sintering technology to develop the P/M bearing caps. After a series of test, inspection and loading test, we defined the manufacture technology of bearing caps and realized mass production.
