At Rocal Extrusions, we specialise in custom plastic extrusion, delivering high-performance, made-to-measure components for a wide range of industries. As a leading custom plastic extrusion manufacturer, we combine in-house tooling, expert design support, and dependable turnaround times — making us a trusted partner among custom plastic extrusion companies across the UK.
Why Choose Custom Plastic Extrusion?
Standard solutions don’t always meet unique performance needs. That’s where custom profile plastic extrusion comes in — enabling you to create components engineered precisely to your specifications. Whether it’s a complex form, a robust seal, or a lightweight structural part, our team supports your project from concept to completion. With experience in custom PVC extrusion and multi-material designs, we bring flexibility and precision to every extrusion challenge.
Standard Plastic Profiles
While our strength lies in custom plastic profile extrusion, we also offer a wide selection of standard plastic profiles for quick and cost-effective supply. Manufactured at our Lincolnshire facility, these ready-to-use profiles are ideal for common applications across multiple sectors. Each one is built to the same quality standards as our bespoke extrusions, offering reliability, consistency, and long-term performance.
To support more advanced performance needs, we also offer a range of specialist extrusion capabilities, starting with co-extrusion.
Co-Extruded Profiles
Our co-extrusion process allows us to combine two or more materials into a single profile, delivering added functionality and efficiency. By blending materials with different properties — such as a rigid inner core and a flexible exterior — we create solutions that meet multi-functional requirements. As specialists in custom profile extrusion, we help our clients solve complex design problems with innovative, dual-material profiles.
Flexible Plastic Extrusions
Where movement, sealing or cushioning is critical, our flexible plastic extrusions offer the perfect balance of adaptability and strength. Widely used in sectors like automotive, construction, and leisure, these profiles are built to perform under pressure while maintaining shape and integrity.
Our experience in custom profile plastic extrusion allows us to engineer flexible components that align with your product goals and environmental demands.
Rigid Plastic Extrusions
When structural integrity is key, our rigid plastic extrusions deliver. Designed for applications where stability, precision, and strength are non- negotiable, these profiles are commonly used in construction, fenestration, and industrial settings. Manufactured in our Lincolnshire facility, they are engineered to offer dimensional accuracy and resistance to environmental stress, all while meeting the specifications of your project.
Whether you need a complex custom PVC extrusion, a dual-material co- extrusion, or a simple profile made to order, Rocal Extrusions is here to help. As a trusted name in custom plastic extrusion, we support clients across industries with the expertise, technology and responsiveness they need to succeed.
