Metal Injection Molding


Request Information


This U.S. owned and trained facility is located in Bangalore, India. Although located in a low cost region of the world, providing competitively priced parts only begins to tell the story of this world-class, TS-16949 facility. This overseas facility excels in providing one-on-one engineering and technical support to each one of their customers, providing a glimpse of the commitment to service and performance. Engineering and customer service support staff are located both in the United States and in India, and warehousing is located throughout the world.

Metal injection molding is still a relatively new technology, but continues to grow dramatically around the world. Best described as a combination of the powdered metal and plastic injection molding processes, parts are produced by mixing blended powders, injection molding the parts, debinding and then sintering. The resulting parts are generally complex in shape, and have properties similar to wrought materials.

The metal injection molding facility has several hundred employees, over 50 molding machines, multiple sintering furnaces, complete toolroom and in-house feedstock compounding to match your specific requirements. Additionally, this facility has several years of experience producing millions of parts in thousands of different configurations, ranging from the simple shaped to the very complex in design. Different from many current metal injection molders, this company will do low, medium, and high volume quantities. Capacity is not an issue, with one of the largest installed equipment bases in the industry today.

Although the molding facility is located in Bangalore, engineering, sales, and warehousing are located in the United States. The highest compliment often received by this overseas MIM provider is when customers say that working with this company is like working directly with a U.S. manufacturer, but with the additional benefit of engineering and customer support rarely matched by current MIM suppliers.

We provide a wide range of secondary services and capabilities:
  • Heat treating
  • Machining
  • Assembly
  • Plating services
  • Compounding of materials
  • Coining

Metal Injection Molding Capabilities

Weight Range

0.5 to 150 grams

Wall Thickness Range

0.5 to 6 mm

Material

Stainless steels: SS 316, SS 304, SS420, SS440 A, B & C, Duplex SS 316, 17-4PH, 17-7PH
Low Alloy steels: 4650, 4140, 4600, and 8620
Magnetic Alloys
Tool Steels like M-2 and S-7
Wear resistant materials including 52100 and Tribaloy
Other materials including Kovar, Invar, and Tungsten Alloys

Tolerances

Typical tolerances are within ± .03% of the base dimension

Design Guidelines

Uniform wall thickness ideal, but not always necessary
Cross holes of any shape, external grooves, surface textures, logos/lettering can be molded into the part
One flat surface ideal for sintering stage, but not mandatory

MIM Features

For complex, three dimensional geometries
Current machining process too expensive or higher quantities not feasible for other processes
Desire to convert several parts into a one piece, integrated design
Current powder metal or die cast parts do not meet strength or performance requirements
