Winning parts in the Metal Powder Industry Federation (MPIF) 2016 Powder Metallurgy Design Excellence Awards competition were recently announced at POWDERMET2016 in Boston, Massachusetts. These award winning parts, stated the MPIF, focus on powder metallurgyÂ’s (PMÂ’s) strong points to gain and extend their competitive advantage, push production capabilities and process tolerances and foster originality.
The Award of Distinction in the Aerospace/Military Category was presented to Advanced Forming Technology, an ARC Group Worldwide Company from Longmont, Colorado, for an aerospace engine ferrule made for its customer Rolls Royce. Made of MIM 17-4 PH stainless steel, the part provides a conductive path between the screen and the engine, while offering support to the single cable and preventing the placement of cable loading on the screen.
The complex component is sintered exactly to net shape, with no secondary operations needed to meet required dimensional specifications. Cost savings were the primary driver for the switch to a MIM (metal injection moulding) part from one machined from bar stock.
