Custom Plastic Extrusions

Our Michigan plastic extrusion facility specializes in versatile, engineered solutions.

Custom plastic extrusion is the process of forcing melted material through a die to form a consistent cross section.  The component is then cooled and may undergo a wide-range of additional processes such as drilling, die-cutting or assembly.

Compatible materials may be co-extruded to create dual- or tri-durometer extrusions that offer dynamic performance properties. Materials can range from common PVC compounds to engineered TPEs, which have physical properties that resemble rubber.

As part of a comprehensive approach to the extrusion manufacturing process, our engineers evaluate all aspects of product development.

Take a look inside our plastic extrusion operations below or explore our case studies to see how we can support your next project.




Rubber and plastic can have many overlapping performance properties. Aesthetics, pricing, rigidity, compression set and ease of extrusion are among the factors engineers consider when deciding between these materials. Explore all the options and determine which is best for your needs.



Engineered plastic was used to create this flexible, dual-durometer component. The result was cost savings and a reduction in part weight. See more with Lauren’s 360 product viewer.

Lauren stands out because of its ability to deliver a wide range of integrated manufacturing capabilities to solve customer problems. This includes dual-durometer extrusions, which are perfect for applications that require high-performance sealing. A “soft” portion delivers excellent sealing properties while a rigid material provides options for easy attachment.

Lauren creates rigid profiles using continuous extrusion as well as injection molding. High-quality rigid products provide the best solutions for applications that require complex profiles, structured support and more. Our design engineers can customize profiles and our die shop provides tooling for a wide array of rigid products.
