What Diversified Plastics does

Diversified Plastics, Inc. (DPI), founded in 1976 by Rod Reid in Missoula, Montana, is a custom plastics engineering and fabrication company serving B2B industrial OEM and aftermarket customers. The company specializes in proprietary injection-molded UHMW-PE, which it claims to be the only manufacturer worldwide capable of producing, along with CNC machining (including 5-axis), cast urethane (durometer range 40A–75D), thermoforming, custom fabrication, overmolding, and its trademarked MultiFab Hybrid Design process that combines multiple manufacturing methods into single integrated parts. It operates across more than ten verticals including water/wastewater treatment, forest & lumber, food processing, mining, agriculture, car wash, egg processing, conveying/packaging, solar power, and poultry.

DPI's revenue model is project-based custom manufacturing: pricing is quote-driven and not publicly disclosed, with tooling costs ranging from roughly $2,500 to hundreds of thousands depending on complexity. The company produces approximately 60,000+ parts per year, ships to 15+ countries, and distributes through a network of territory-based independent sales representatives across the US (Southeast, Pacific Northwest, Mountain, Midwest, Northeast) and international markets, supplemented by an inside sales team and direct website quote requests. Its 3.5-acre campus is scaling to 60,000+ square feet of building space by end of 2025 with four 80,000 lbs silos, eight injection molding machines (19 oz to 311 oz shot sizes), and a fully equipped in-house tool room.

In March 2026, DPI was acquired by The Rubber Group (TRG), a New Hampshire-based rubber solutions manufacturer, and rebranded as Diversified Plastics Industrial Solutions while retaining its Missoula workforce and facilities. The acquisition creates an integrated plastics-and-rubber manufacturing platform serving water/wastewater, food/beverage, industrial manufacturing, and transportation, with combined geographic reach spanning Montana, New Hampshire, and Chicago.
