Compacting
process
The compacting process
is the process that does the mixed powder a compacting by a compacting machine.It does the compacting that fillings into a tooling and compress the mixed powder to, about 1/2 of the height toward length.
Sintering
process
Continuous sintering
furnace
The green compact placed on a wide-mesh endless belt, slowly moves through
a controlled -atmosphere furnace.
The parts are heated to below the melting point of the base metal, held
at the sintering temperature, and then cooled. Basically a solid-state
process metallurgical bonds between the powder particles and thus provides
the P/M parts primary functional properties.
Sizing
process
Repressing
after sintering may require additional sizing or coining tools. Coining
a P/M part reduces its volume, increases density, and improves strength,
hardness and dimensional accuracy. Impregnation
Process
As
for this product, there are 10-20% of pores with volume.
By doing an impregnation in this pore, it makes an oil-impregnated
bearing and sintered structural part with lubrication.
