In the 1970s this process was developed to allow the processing of metal powders by raymond wiech in the us widely considered the inventor of the metal injection molding process.
After molding the part undergoes conditioning operations to remove the binder debinding and densify the powders.
It could produce a large quantity of metal structural functional and cosmetic parts in high precision complex shape good performance and delicate appearance.

Then this feedstock goes for injection molding where the desired shape cavity is present.
From an economic stand point the most promising metal injection molding materials for the mim process are the those that are more expensive.
Powder metal and metal injection molding part manufacturing sofine gian is a professional mim solution provider which was established in 1999.
The rheological properties of the feedstock which consists of the powder and binder mix are of major importance.
Metal injection molding mim is a metalworking process in which finely powdered metal is mixed with binder material to create a feedstock that is then shaped and solidified using injection molding the molding process allows high volume complex parts to be shaped in a single step.
