Metal injection molding of sintering and
general powder metallurgy sintering process is similar, but the metal injection
molding using a large amount of binder, the forming of billet density is low,
the binder is removal before sintering, so injection molding billet sintering
is a bit similar to apparent sintering, the sintering process can produce
larger shrinkage, although the contract is our main purpose of the sintering,
but at the same time the size change has led to distortion, to maintain high
precision needs to be controllable and uniform sintering shrinkage caused by
the evolution of the microstructure is a main factor of product performance.
