Metal Injection Molding (MIM)

Defense Metal Injection Molding (MIM) for Complex, Precision-shaped Defense Market Parts

Metal injection molding (MIM) is an effective way to produce complex and precision-shaped parts from a variety of materials – without machining. It is common for MIM to produce parts for 50 percent less than the cost of CNC machining or investment casting. At the same time, the true value of MIM comes from its ability to produce parts with complex shapes, superior strength, and excellent surface finish in combination with low- to high-volume manufacturing capability. 

With MIM, your total cost savings result from the function of shape complexity, production volumes, size of the part, and material used. Sizes of parts can be up to 150 grams, although most parts produced are less than 30 grams. Phillips-Medisize can also meet your smallest requirements, with the capability to mold metal parts in a variety of materials ranging from 0.0001 – 0.003 cubic inches. Tolerances can be held to as little as ±0.0005 inches. 

When you partner with Phillips-Medisize, you align with a world-class, ITAR-compliant provider of MIM services that follow strict MIL-STDs. The defense MIM services available to you include injection molding, insert molding, overmolding, multi-shot molding and micro molding. You benefit from metal components that feature superior quality and dimensional repeatability in the most compressed time frame possible. 

Built MIM Tough – The FN Herstal FNP-45

FN Manufacturing collaborated early with Phillips-Medisize to create the FNP-45. A first-rate, U.S.-manufactured pistol, the FNP-45 can withstand rigorous environmental testing, including a 25,000-round endurance test without any part breakage.
