Powder Metallurgy Parts—Performance

In pressing process, due to friction between mould and powder, powder and powder, make the pressure distribution not uniform, also led to un-uniform microstructure of blank, Powder metallurgy parts(http://www.zcmim.com/bymaterial.shtml) it will result in un-uniform shrinkage during sintering process. Therefore we had to reduce sintering temperature to reduce this effect, which make large porosity and less density, seriously affecting product Original article link： http://www.zcmim.com/article/powder-metallurgy-parts_1.html
