Precision Powder Metallurgy Sinter Mechanical Parts MIM Factory
The sintering Purpose-to increase strength & hardness of a green compact Carried out at a temperature below the highest melting constituent. Furnaces may be either the electric resistance,gasfired or oil fired type. Principal variables-temperature(generally within 70-90% of the melting point of metal or alloy),time(10min.-8 hours)&furnace atmosphere. Sintering process is concerned with -diffusion(surface of particles as temperature rises) -densification(decreases porosity,increase particle …
The sintering cost
Sintering furnace design depends on the expected production batch, the sintering materials, operating expenses, the types of sintering atmosphere and cooling speed after sintering. PIM with batch furnace charge can be from 1 kg to 300 kg. In the PIM production, the diameter of the sintering furnace can achieve 2-3m, a typical sintering period is 12-36h. On the other hand,adopted …
