Custom Rubber & Plastic Extrusions


Trim-Lok offers a variety of custom rubber and plastic extrusions.


Custom Extrusion Capabilities

Custom extrusions are designed to meet your unique application’s specifications, whether it’s for trimming or sealing or simply for a decorative edge.

Trim-Lok extrudes 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 render 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:
