Process of Metal injection molding


Metal injection molding (referred to MIM) is a new technology of powder metallurgy and plastic molding to combine metal parts,high-volume manufacturing of small rapid development of complex precision metal parts.

Feeding: about 60% of metal powder mixed with  40% of binder into a homogeneous feed.
. .
Injection molding injection molding machine mold
Injection molding: injection molding machine will feed into the injection molding process similar to injection molding.The shape and structure of the parts forming the mold.
. .
Debonding process 5 6
Debonding: the use of physical or chemical process for removing parts of the binder components from the mixture of metal powder and a binder into a simple metal parts, the volume shrinkage, shape and structure unchanged.
. .
Sintering process 7 mould
Sintering: This process is the densification of the part, further contraction volume, shape and structure unchanged, when the relative density of ≥ 95%.
