ATW Companies, a provider of custom manufactured metal components and services, has announced that its Parmatech Corporationsubsidiary was a winner of the 2011 Powder Metallurgy Design Excellence Awards Competition, sponsored by the Metal Powder Industries Federation (MPIF). Parmatech earned the grand prize in the hand tools/recreation category for a large-game 420 stainless steel hunting arrowhead, the 300Xtreem broadhead, made for Optek Precision Tooling Ltd.
Fabricated by the metal injection molding (MIM) process, the thin blade features a straightness necessary for accuracy and the external thread for attachment to the arrow shaft is molded in the design. The part is formed to a final density of 7.7 g/cm3 and has a 48-52 HRC hardness range. Going the metal injection molding route saved 50% of the cost of machining the broadhead from stainless steel bar, according to the company. The customer sharpens the arrow head edge, the only secondary operation performed.
