Custom Extrusion Capabilities: Materials & Shapes

Material & Shape Capabilities: Custom Plastic & Rubber Extrusions


Specially Engineered Custom Rubber & Plastic Extrusions

Trim-Lok can provide a variety of shapes and custom-formulated compounds for your unique application. We extrude single material, as well as materials of different durometers or multi-material (co-extrusion), into the same part.

Whether it’s custom-formulated plastic tubing or an intricately detailed custom rubber gasket, our highly experienced and dedicated engineering team can engineer a cost-effective solution to meet your exact specifications.

Markets We Serve

We are equipped to provide solutions to customers who need rubber extrusion manufacturing services across a variety of industries:


Product Forms & Shapes

Our abilities range from the standard U-channel and P-profile and D-profile shapes for trimming and sealing to decorative trim extrusions, both large and small, and everything in between.

  • • Simple and complex profiles and shapes
  • • Tubing, cord and rod
  • • Hollow and solid

With our in-house tool shop, we can manufacture custom dies to nearly any configuration to produce any extrusion that can fit our equipment and capabilities.
