We know that we are only as good as the last project we delivered and all of our customers’ brands are affected and measured by every piece we manufacture and deliver.

Our History

Houston Plastic Products enjoys a rich heritage of delivering high-quality plastic products and manufacturing services for over 60 years. Our 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 are committed to serving customers across many industry segments, from energy and industrial to medical and consumer products – virtually anywhere plastic products can be found.
