Peerless Precision Inc.
Job ShopEstablished 197626-50 Employees
Peerless Precision, Inc. ( PPI ) is a small, 26 person job shop that specializes in the manufacture of precision machined parts for the aerospace, defense, and medical devices industries. We are extremely competent when tolerances of .0001″ or better are required and have delivered 1 helium light band in flatness, .000005″ in roundness and .003″ wall thickness. We are AS9100 Rev. D and ISO9001:2015 certified. Our services range from prototype through production runs. We also provide assemblies and project management. We work with both raw stock (titanium, stainless steel, aluminum, magnesium, carbides, etc.,) and castings. PPI is a dock to stock supplier to Triumph Engine Control Systems in West Hartford, CT. We also serve clients such as FLIR Systems, Eaton Aerospace, Aircraft Component Design, Inc., Zygo Corporation, and many others. Many of the components we manufacture are used in thermal imaging and fuel and engine systems. Where companies are looking to consolidate their vendor base, PPI’s project management skill in working with precision machine shops locally, offers total, single source capability. Those shops add screw machine, large part manufacture, welding, and much more to PPI’s broad internal capabilities. Additionally, PPI works with a firm providing reverse engineering services enabling us to produce low volume, legacy parts at competitive prices.
