our History

PTI is a privately held company, founded in 1984, which operated under the name of Proto-Tech Industries until 1987. Proto-Tech Industries produced functional prototype molds and injection molded samples before changing its 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.
