Custom Plastic Extrusions

Over the decades, Gemini and Sierra Plastics have developed over 5,000 plastic extrusion profiles. This means you can be confident that we have the resources and expertise to help you develop your automotive seating component’s profile design.  We have the engineering expertise and in-house tooling capabilities to help develop the right profile for your plastic extrusion application.

Nearly 70% of the Automotive Seats in North America are built with our Custom Plastic Extrusions

You will probably never see most of Gemini Plastic’s products, but two out of every three drivers in North America lean on our custom plastic extrusions every day (literally)! In this case, we are referring to plastic extrusion products used for automotive seating.

However, we manufacture far more than custom plastic extrusions for the automotive industry. We also provide the Lawn & Garden, Medical, Consumer, Transportation and Appliance industries with plastic extrusion and profile extrusion components.

Whether it’s a color-matched close-out for a medical cart, a shape maintainer helping direct airbag deployment, a through routing electrical wiring, or a seal protecting your vehicle’s interior from the elements, you can count on Gemini and Sierra Plastics’ profile extrusion components to meet and exceed your needs.
