MIM (METAL INJECTION MOULDING) is a part of powder metallurgy manufacturing process where the metal powder is compacted or brought to required shape likewise plastic injection molding which is followed by pre-sinter process in which secondary binder is removed. Thus giving a final product after sintering process. Thus one can say it a unique combination of plastic injection molding and powder metallurgy. This combination is industrially beneficial technology for allowing engineers to create complex shaped tiny metal parts which are complicated in design.

The Metal Injection Moulding (MIM) Process offers the Following Asvantages :

Cost-Effective Manufacture of high Volume Complex parts.

Reduced Production time Compared with investment casting.

Net-sape Manufacture with minimal material waste (Runners, Sprues Recyclable in - House): More Significant as materials costs rise.

Mecanical Properties Superior to Castings and Oter PM Parts Reflecting Fine Particle Size and high Sintered density.

Properties Equivalent to Wrought Alloys.

Wide Range of Pre-alloys and Master alloys available.

Minimum of finishing operations.


Stainless Steels

17-4PH - Best Combination of Strength & Corrosion Resistance.

360 - Excellent Corrosion Resistance.

420 - Hig Hardness.

Low Alloy Steels

2200 - Similar to PM FN-0200, Good Magnetic and tougness Properties.

4605 - High Treatable, High-Steel, Up to HRC 52.

4140 - Heat Treatable, High-Strength Steel, Up to HRC 60.

Controlled Expansion Alloys

Fe-Ni - The alloy Composition (ie, Invar, Alloy 42, etc) can be tailored for the application's thermal expansion requrement.

F15-AKA Kovar, the alloy is engineered for hermetic glass-metal seals.
