The Award of Distinction in the Automotive-Chassis Category went to Indo-MIM Pvt. Ltd., India, for a MIM-4605 low-alloy steel top plate and check shim stop made for its customer Multimatic Dynamic Suspensions. The mating parts go into shock absorbers on the Chevrolet Camaro sports car. The MIM design provided increased repeatability and accuracy, providing an estimated 25% cost savings.
Lawn & Garden/Off-Highway: FMS Corporation
The Award of Distinction in the Lawn & Garden/Off-Highway Category was given to FMS Corporation, Minneapolis, Minnesota, for a sinter-hardened steel pivot shift fork made for Team Industries. The part goes into a shifting mechanism in an all-terrain vehicle transmission. The two sets of journals are an absolute requirement as they enable the fork to pivot, which is its very function.
Aerospace/Military: ARC Group Worldwide

An Award of Distinction in the Aerospace/Military Category was earned by ARC Group Worldwide, Longmont, Colorado, for a MIM-4140 low-alloy steel latch made for Sig Sauer Inc. The internal latch drives a subassembly for the telescoping feature of the collapsible stock on MCX and MPX rifles. The part was designed for MIM as it could not be economically made using any other fabrication method.
Hand Tools/Recreation: Indo-MIM Pvt. Ltd

An Award of Distinction in the Hand Tools/Recreation Category went to Indo-MIM Pvt. Ltd., India, for a set of metal injection moulded parts, including a barrel block, gas block, bolt catch, 7.62 NATO mag conversion bar, ejector retainer, and extractor link, that go into an MDR rifle made by Deserttech. The MIM-designed parts replaced ones that were machined, and reduced the cost by 30% while manufacturing lead-time was cut in half.
Hardware/Appliance: ASCO Sintering Co.

An Award of Distinction in the Hardware / Appliance Category went to ASCO Sintering Co., Commerce, California, for a copper-infiltrated steel bolt used in a commercial door lock system. The part’s complexity, with its 9 levels, rivals that which is more typically seen in parts produced via MIM. The bolt is pressed and sintered to its final shape without any secondary operations. It is estimated to save 60% over the cost of other manufacturing methods.
Industrial Motors/Controls & Hydraulics: Capstan

An Award of Distinction in the Industrial Motors/Controls & Hydraulics Category went to Capstan, Wrentham, Massachusetts, for a copper-steel clutch piston. The part is used in an industrial power takeoff system, a relatively new development for PM pistons. It is a multilevel compacted part that, combined with multiple secondary processing steps, yields a highly precise, machined, and sealed PM component, an economically attractive alternative to a machined die cast one. This component is a prime example of how innovative machining techniques, performed on precise, near-net as-sintered blanks, can add great value and open up new markets for the PM industry.
