Custom Rubber and Plastic Extrusions


Custom Rubber and Plastic Extrusions
Engineered Specifically for your Application

Trim-Lok brings the most experienced team in the industry toward the development of custom fabricated solutions across all the industries we serve.  Whether it’s custom formulated plastic tubing or an intricately detailed gasket, Trim-Lok can engineer a custom extrusion solution to meet your exact specifications and be cost effective as well.  Our abilities range from the standard u-channel and p-profile shapes for trimming and sealing to decorative trim extrusions, both large and small, and everything in between!  


Trim-Lok’s highly experienced and dedicated engineering team brings high caliber mechanical design, excellent materials knowledge and strong manufacturing expertise.  With our in-house tool shop, custom dies can be manufactured to nearly any configuration to produce any extrusion that can fit our equipment and capabilities.   We are equipped to provide a full service “solution” to our customers.  From simple to complex application needs our team of engineers is ready to ensure that your custom part will be right by offering the following:

  • •On-site customer reviews of the problem
  • •Engineering design and development using the latest in 3D CAD software and FEA
  • •Reverse engineering as required
  • •State of the art rapid prototyping techniques
  • •Internal lab testing of the desired specifications
  • •Specific selection of materials to match the customers’ requirements,
  • •On-site fit trials of first articles
  • •And more!

Trim-Lok can provide custom formulated compounds for your unique application.  We extrude single material, as well as materials of different durometers, multi-material (co-extrusion), into the same part.  If you need an EPDM sponge rubber seal with a rigid PVC pedestal that mates perfectly with an existing track, we can do that.  If you want to reduce your labor and SKU count by combining several parts into 1, we can do that.  If you need to create one part that grips, seals and looks good, we can do that!  If you’re looking for a rubber or plastic extrusion as a substitute for wood or metal, we can do that too! 

Custom Profile Extrusions are available with any of our secondary operations and additional services.  Our extensive list includes mitered corners, holes, notches, or special cut outs to suit your specific application and can include pressure sensitive adhesive (PSA) tape backing, custom packaging and custom kit assemblies.  We can provide finished parts cut to length or provide reels of extruded stock, depending on the customer’s request.   See our full list of additional services below.

At Trim-Lok, we adhere to strict quality control standards to provide high quality and competitively priced plastic and rubber trim and seal parts, both off the shelf and custom engineered.  We invest in highly skilled employees and modern equipment so that you can count on reliability, efficiency and repeatability.  From excellent customer service to on-time deliveries, keeping our customers satisfied is our highest priority.  Let Trim-Lok design and manufacture a custom extrusion solution for you.

Trim-Lok now offers Flammability, Smoke and Toxicity (FST) certified rubber materials.  The addition of FST materials expands our already extensive extrusion capabilities.  Trim-Lok can now further enhance their offerings to customers that have Smoke and Flame requirements typically required in applications in mass transit industries such as marine, aerospace, bus and rail, to protect mass transit passengers.

If you require a material we have never run, we are always ready to bring our knowledge to work on a new opportunity.  Several of our parts are at the forefront of innovation, and we are willing to evaluate any challenge.  Let us have a look at your current opportunities and see how we can help you achieve your objective.
