Miller Plastics is owned and run by Donnie Miller whose hard work, long hours, and dedication to delivering the highest quality plastic components helped build a solid foundation for a strong company poised for the technology boom. Donnie’s interest in computers dates back to his youth. His commitment to remaining current with technology has led him to invest continually in solutions, such as computer-controlled robotic manufacturing equipment.

As a result of these ongoing upgrades, Miller Plastics remains an industry-leading plastic machining, fabricating, and tank manufacturer when it comes to maximizing overall productivity, as well as achieving close tolerances and the highest levels of precision on every job. Since there was no plastic manufacturing equipment in the 1980s, Donnie and his father worked with woodworking and metalworking equipment manufacturers to develop some of the early plastic working tools and machines.

Miller Plastics has remained an industry-leading plastic tank manufacturer by accessing the best technology, maintaining a highly skilled workforce, and cultivating a loyal customer base.

Miller Plastics is located in Burgettstown, PA, 25 miles west of Pittsburgh, and near Pittsburgh International Airport.

Our commitment to excellence is embodied in our state-of-the-art, 50,000-square-foot manufacturing facility.
