DELAND, Fla., June 2, 2014 /PRNewswire/ -- ARC Group Worldwide, Inc. (NASDAQ: ARCW), a leading global provider of advanced manufacturing and 3D printing solutions, announced today its ARC MIM company, won three MIM awards at the Metal Powder Industries Federation ("MPIF") World Congress on May 20, 2014.
FloMet, an ARC MIM company, earned the Grand Prize in the Medical/Dental Category for two 5 millimeter tines – one fixed, one moving – that go into a thermal tissue fusion and dissection system for a major medical OEM customer. The system utilizes direct thermal energy and pressure to effectively seal, transect, dissect, and coagulate tissue. Fabricated via MIM from 17-4 PH stainless steel, the tines overcame many molding and processing challenges, including the fixed tine's length and thin-rib requirements, as well as the need for straightness over its entire length for full functionality with mating components. Highly innovative tooling and advanced thermal processing techniques were employed to produce two components in a final as-assembled condition with only minimal secondary operations. FloMet's expertise in MIM technology created a compelling case for the customer to redesign the product away from its legacy manufacturing process.
FloMet also won the Grand Prize in the Electronic/Electrical Components Category with a three-piece assembly, including a nozzle interface, outer nozzle, and metal collar. The MIM components were for a leading consumer electronics company, used in their high-end, sound isolating earphones that enable user-customizable frequency responses. Made via MIM from 316L stainless steel, the components achieved the objective of producing final net-shape parts that not only met the cost demands of the highly competitive professional-audio market but maintained a cosmetically perfect surface, which is critical in a consumer product with a clear exterior.
AFT, an ARC MIM company, earned an Award of Distinction in the Hand Tools/Recreation Category. The MIM component was for a lock hood, made from 4605 low-alloy steel. The hood's complex geometry presented a challenge for maintaining the large undistorted U-shape which is needed to coin the lock hood into its final tolerance. This was accomplished using a unique sintering and staging approach that utilizes an "active" setter made of a feedstock having a similar shrink rate to the hood. AFT's unique MIM capabilities allowed the customer to offer the end product at the desired price point in their highly competitive consumer market.
