Precision Products Machining Group

Precision Products Machining Group

Precision Products Machining Group (PPMG) was founded in 2012 as a holding company for precision-manufacturing businesses serving heavy industries. The firm is structured as a family office but does not publicly disclose underlying wealth origin or principals. The firm's portfolio spans open gearing and gearboxes (through Overton Chicago Gear, which consolidates brands dating to 1888) and high-precision machined components for aerospace and defense (through Crown Precision and Sungear). Target end-markets include oil and gas, mining, aerospace, defense, power generation, marine, locomotive, and medical. PPMG emphasizes serving customers who demand high performance in extreme operating conditions, from miles below the surface in oil fields to miles above in aircraft. The company has core competencies in gear design, material selection, heat treat processes, and precision machining. PPMG operates across 10 locations with over 460 employees. The firm's corporate headquarters is in Addison, Illinois. It has not disclosed total AUM, deployment numbers, or professional team size. No recent operational events were found in the last 24 months from public sources. PPMG's structural differentiator is its focus on a narrow, high-precision manufacturing niche within heavy industries, operating as a holding company that adds value through complementary product lines and services rather than financial engineering. The firm seeks growth through new customers, markets, and products, positioning itself as an agile operator within a concentrated industrial vertical.
