Rubber Extrusion Process with Elbex: From Concept to Creation

David Garman • June 20, 2025

Rubber extrusions are incredibly versatile, used across a wide range of industries. At the same time, we recognize that understanding the basics of rubber extrusion for beginners can be challenging. In this blog, we’re going to provide a step by step overview of the rubber extrusions process, and how Elbex’s approach to the rubber extrusion process can benefit your company.


The Fundamentals of Rubber Extrusion


Rubber extrusion is a process in which uncured rubber materials (such as EPDM, silicone, neoprene, and nitrile) are forced through a shaped die. This is done to create a long, continuous profile, reducing waste and making the production of rubber extrusions more efficient. The extruder forces the rubber through the die, which can be adapted to create different shapes for different applications.


The continuous profile then goes into a cooling system, where it cures and hardens. After it is cured, handling equipment allows the long profile to be cut to length to form multiple extrusions.



Elbex's Streamlined Rubber Extrusion Process: A Step-by-Step Overview


At Elbex, we follow a five-step process for streamlined rubber extrusion creation:


  • Step One: Initial Consultation and Design Input. Most projects start when the client provides design information. This usually comes in the form of a drawing or sketch that provides a visual of the extrusion, or a physical sample that we can reverse engineer.


  • Step Two: In-House Die Creation. Once we have a finished design, we manufacture our rubber extrusion dies in-house. By eliminating the need for external vendors, we can lower costs and provide a faster turnaround. This also ensures that the die is the proper shape for the extrusion.


  • Step Three: The Extrusion Process. Once the custom-made die is ready, we use our extrusion equipment to force the heated rubber through the die. The right level of heat and pressure is essential to maintain the right shape during this step.


  • Step Four: Curing and Vulcanization. After going through the die, the rubber is vulcanized (or cured) with chemicals like sulfur to help it harden and improve its physical traits.


  • Step Five: Cooling and Handling. After the extrusion has cured, it needs to cool. Cooling completes the hardening process, after which the rubber can be cut to length or spooled based on application needs.

In industries like mass transit and construction, secure fitting and protected edges are key to the durability and safety of many applications. Rubber extrusions, particularly custom extruded u-channels and variations like ribbed rubber channels can play an essential role in these areas – and Elbex’s expertise in providing custom solutions will help you move forward with confidence. Understanding U-Channel Rubber Extrusions U-channel rubber extrusions are named for their distinctive U-shape, which allows them to fit over edges or within channels on mating pieces to ensure a secure fit and protect edges. The size and thickness of the legs and base should be adapted to the needs of the application, since precise dimensions are needed to get a secure fit. Depending on needs, extra features like ribbed rubber channels can be added for increased grip, vibration dampening, or sealing. As with other rubber extrusions, various materials, such as EPDM, neoprene, or silicone can be used for U-channels. The right material depends on the application’s environmental conditions (like temperature, chemicals, and UV exposure), as well as performance requirements such as flexibility and durability. Diverse Applications Across Industries U-channels serve a variety of important functions. They can be used as edge guards to protect surfaces from damage and provide a finished look, such as in automotive door edges, metal paneling, or machinery housings. The tight fit of these rubber extrusions within the channel also dampens vibrations and prevents unwanted movement between components. This is especially important for preventing excess wear and promoting structural integrity in transportation equipment and other machinery. U-channels are also used to create seals against dust, moisture, and other environmental elements. Weatherstripping in homes and glazing seals on building and automotive systems are common examples of this. With the right materials, U-channels can provide essential protection, even in extreme environments that undergo frequent temperature changes. Elbex’s Expertise in Custom U-Channel Solutions At Elbex, we provide a comprehensive level of support in addressing your U-channel needs.
