July 12, 2010 - Winners of 2010 Powder Metallurgy Design Excellence Awards Competition, sponsored by Metal Powder Industries Federation, were announced at PowderMet2010. Receiving grand prizes and awards of distinction, winning parts are examples of powder metallurgy's precision, performance, complexity, economy, and innovative design advantages. Grand Prize winners included GKN Sinter Metals, Smith Metal Products, FloMet LLC, and Advanced Materials Technologies Pte Ltd

Grand Prize AwardsGKN Sinter Metals, Auburn Hills, Mich., won the Grand Prize in the Automotive- Transmission Category for a fully integrated planetary carrier and rocker-style one-way clutch assembly, an industry first. Designed and made for Ford Motor Company and used in the Ford Super Duty truck five-speed automatic transmission, the application is a three-piece sinter-brazed planetary carrier. It consists of both PM copper-steel and sinter-hardened materials, assembled with a single-pressed cam plate, which is also sinter-hardened. The application consists of four parts (cam plate, spider, clutch hub, and rocker plate) that are combined with 12 steel rocker struts and springs, a retainer plate, and snap ring to form the one-way clutch planetary carrier assembly. Providing a cost savings of more than 25 percent, the PM assembly replaced a two-piece riveted planetary carrier. GKN achieved a density of 7.25 grams per cubic centimeter in the single-pressed complex sinter-hardened cam form without warm compaction and hightemperature sintering. Secondary operations are limited to machining the bearing journals, oil holes, and pinion holes.....MORE
