About Us

Diversified Plastics, Inc. is a custom plastics fabrication and engineering company and family business founded by Rod Reid in Missoula, Montana. The company began in Rod’s garage in 1976 as a supplier of engineered plastic wear strips for lumber and pulp mills in the surrounding Missoula area. From those humble beginnings, Diversified Plastics has grown to become a North American leader in plastics engineering and fabrication.

Today, Diversified Plastics is led by Rod’s son, Brad Reid, a mechanical engineer, and an experienced team of manufacturing professionals. More than 60 employees offer comprehensive services to our customers from urethane casting, thermoforming, machining and injection molding to design, engineering, and tool and die services. We deliver tens of thousands of parts a year, domestically and abroad, for use in a wide range of industries.

At its heart, Diversified Plastics is still much the same as the one founded in Rod’s garage over 40 years ago. Our people are as friendly and helpful as they are knowledgeable and we stand behind the products we manufacture. We are innovative in our processes and we believe the only way to excel is to continuously improve. We work collaboratively with our clients to solve their challenges and improve their efficiency.

When you choose Diversified Plastics, whether it’s for a single part, a small run, or a multi-year contract, you’ll get the same attention to detail, the same problem-solving approach, and the same quality solution we’ve provided since we were working out of Rod’s garage in 1976. That’s the Diversified Plastics promise. Always has been. Always will be.
