ASK & WE ANSWER

Metal Injection Molding is a special process in which finely powdered material is mixed with a binder to create a feedstock and then it is injected to get a solidified complex shape in a very lesser cycle times compared to the conventional process.

Yes, MIM parts can be heat treated & plated as done on a conventional machined, cast or forged product. INDO-MIM maintains in-house heat-treating and plating facilities to supply fully finished components.

MIM technology typically uses off-the-shelf machinery with enhancements. INDO-MIM has long term relationship with its US and European equipment suppliers who cater  to our specific requirements.

MIM Caters to tight tolerances. However, tolerances are highly dependent upon product geometry. Tolerances beyond what MIM is capable of are achieved by post-machining operations.

As with any technology, MIM has limitations. Product weight is limited to a maximum weight of about 240 grams (although economics generally push the weight limit to no more than 50 grams). Certain geometrical features can also present a problem (like extremely thin or thick cross sections). INDO-MIM will advise on the design options to suit your requirements.

There is nothing right or wrong here. As a thumb rule, if a drawing has more than 20 dimensions, it may be a good part for MIM.

While INDO-MIM accepts all quantitative requirements of the customers lower volumes become uneconomical due to the fact that the customers   have to invest on a tool.

Start early. Involve us at the design stage.  INDO-MIM will assist you in the application of MIM, whether it is a new component or a conversion from an existing metal forming technology.

Typical alloys include high-strength steels, stainless steels, plus Ni and Co super alloys. Other materials processed include titanium.

MIM (Metal Injection Molding) is a manufacturing technology that combines the shape making complexity of Plastic Injection Molding with the material flexibility of Powder Metallurgy.

Fine metal powders are combined with  binders  to form a feedstock. When heated, the feedstock becomes a viscous slurry, which is then injected under high pressure into an engineered mold to form the desired shape component. Upon cooling, the part is ejected from the mold and then subjected to a process (called debinding) to remove binder constituents. The final step (sintering) subjects the part to high temperature in a controlled atmosphere to fuse the metal powders together into a near fully dense solid

No, only the binders are melted, allowing the powders to flow like a plastic material. Upon cooling, the binders solidify giving the part strength for handling. The part must be subsequently sintered to high density to achieve the required mechanical properties.
