PTI Engineered Plastics History

PTI is a privately held American company, founded in 1984, which operated under the name of Proto-Tech Industries until 1987. Proto-Tech Industries produced functional prototype injection molds and injection molded samples before changing our name to PTI Engineered Plastics. The name change was driven to better reflect the turnkey, mind-to-manufacturing operations that PTI is today. In 2010, PTI expanded its design capabilities with the launch of PTI Design, an in-house design studio that specializes in product innovation and development. Today, we have representation throughout the United States, including California, Illinois, Georgia, New Hampshire, New York, North Carolina, South Carolina, Ohio, Colorado, Texas, Utah, and Minnesota.
