MIM wins awards

Metal Injection Molding (MIM) was a winner at the 2009 Powder Metallurgy Design Excellence Awards Competition, sponsored by the Metal Powder Industries Federation. Two of the five grand prizes went to MIM parts, while a third received an award of distinction. A 316L stainless steel compressed air nozzle produced by FloMet of Deland, Florida, won the hand tools/recreation category Grand Prize. The part has a density of more than 7.6g/cm3, an ultimate tensile strength of 75,000psi, yield strength of 25,000psi and a 50% elongation. An external connector for a high-performance fiber-optic module won the Grand Prize in the electrical/electronic components category. The part is a 17-4 PH stainless steel MIM flagstaff nose or EMI nose shield. The part has a density of 7.5g/cm3, tensile strength of 130,000psi, yield strength of 106,000psi, an eight percent elongation, and a 27 HRC as-sintered hardness. Parmatech Corp. of Petaluma, California, received the Award of Distinction in the hand tools/recreation category for a 420 MIM stainless steel housing block used in a 45-caliber handgun. Formed to a final density of 7.7g/cm3, the part has a tensile strength of 261,000psi, yield strength of 218,000psi, and a 48-52 HRC hardness range.
