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.

Today’s mass transit systems don’t just need to get from Point A to Point B. They also need to provide durability, safety, passenger comfort, and long-term performance — and mass transit rubber extrusions play a critical role in achieving exactly that. A wide variety of custom extruded rubber profiles for mass transit applications help vehicles meet the complex design specifications of mass transit systems. From vibration dampening rubber components for transit vehicles that improve ride quality and equipment longevity to UV resistant rubber profiles for exterior transit applications that offer protection against environmental exposure, these small parts matter. And with ELBEX’s expertise and capabilities, you can get the transit support you need. The Critical Role of Rubber Extrusions in Mass Transit Rubber extrusions are essential protective and functional components in buses, trains, rail systems, and transit infrastructure. Most often found in the form of door seals, window gaskets, edge trims, expansion joints, and protective bumpers, they ensure a transit system’s safety, durability, and compliance with industry standards. Precision and consistency are essential for delivering these results. One key role of mass transit rubber extrusions is to absorb vibrations. Vibrations can significantly affect vehicle performance, passenger comfort, and component lifespan, which makes vibration dampening rubber components critical for absorbing shock and reducing mechanical stress. Transit vehicles also face ongoing exposure to sunlight, temperature swings, moisture, and environmental pollutants. This makes UV resistant rubber profiles such as EPDM essential for maintaining vehicle structural integrity and appearance. At ELBEX, we understand the importance of selecting materials that can withstand harsh outdoor conditions while also controlling transit-related vibrations.
