Houston Plastics Products


About Us

plastic injection molding

Houston Plastic Products enjoys a rich heritage of delivering high-quality plastic products and manufacturing services for over 50 years. The company was established in the late 1940s by Fred Allen as the Fred Allen Company. In the beginning, we operated as a tool shop, and in the early 1950s we began supporting our customers with injection molding. Houston Plastic Products was eventually spun off as its own full-service plastic injection molding and custom manufacturing company. Today, we’re committed to serving customers across many industry segments, from oil & gas and industrial to healthcare and consumer products - virtually anywhere plastic products can be found.

We help customers throughout many phases of the manufacturing process, specializing in high-quality, custom components where exacting tolerances are required. Houston Plastics Products uses engineering grade resins and high-grade materials to ensure all products perform exactly as intended - with a strict adherence to our customers’ engineering specifications.

Plus, with our commitment to safety, advanced quality-assurance and quality control protocols, and a relentless pursuit of complete customer satisfaction, we work hard to earn the trust of our customers every day. We know that we’re only as good as the last project we delivered - and all of our customers’ brands are affected and measured by every piece we manufacture.

The Houston Advantage
Strategically-located in the heart of Houston, TX, we have the ability to serve our customers’ needs anywhere in the world. The diversity of the Houston business climate allows Houston Plastic Products to work in a variety of industries - and take advantage of a breadth of different customer types and partners we’ve worked with over the years. It’s because of this unique business mix that we’re experienced to handle any project that comes our way.
