Mack Tool & Engineering

What Mack Tool & Engineering does

Mack Tool & Engineering is a privately held precision machining services provider founded in 1988 and headquartered in South Bend, Indiana. The company manufactures custom precision machined components for the medical instrument, orthopedic implant, and aerospace industries, with additional capacity for general precision machining projects. Its core technology platform comprises an extensive array of CNC equipment including four and five axis CNC mills, four axis CNC wire EDMs, CNC lathes with bar feeders, CNC plunge EDMs, and CNC coordinate measuring machines, complemented by advanced palleting robotics and integrated 3D CAD/CAM capabilities. Material expertise spans aluminum, stainless steel, titanium, hastelloy, beryllium copper, and engineering plastics.

The company is qualified into highly regulated supply chains through ISO9001:2015, NADCAP, AS9100D, and ITAR compliance, which together function as a regulatory moat limiting competitor entry into medical and aerospace OEM sourcing. Revenue is generated through quote-based custom manufacturing services, with project scope ranging from one-off prototypes to production runs of hundreds of pieces. The go-to-market is direct B2B field sales targeting enterprise buyers in medical device, orthopedic implant, and aerospace component manufacturing, with lead capture via website and phone. Value-added services include in-house deburring, cleaning, assembly, inspection, and testing, with additional heat treating, plating, chemical coatings, brazing, and welding delivered through NADCAP-approved partner suppliers. The business has 11-50 employees and is believed to operate from a single South Bend facility.
