Rubber is a highly adaptable material used across countless industries, from automotive and construction to aerospace and electronics. One of the most efficient methods of producing rubber components is rubber extrusion. This process allows manufacturers to create continuous lengths of rubber with specific cross-sectional shapes, offering unmatched versatility and customization.
**Extruded rubber products** are found in weather seals, tubing, gaskets, bumpers, and more. Whether in cars, doors, industrial machinery, or electrical enclosures, extruded rubber plays a silent yet critical role in protecting, sealing, insulating, and cushioning.
Extruded rubber refers to rubber that has been forced through a shaped die to create long, uniform profiles. This is done using an extrusion machine, which heats and presses raw rubber through a die – a tool designed to shape the rubber into a specific cross-section (e.g., U-channel, D-shape, tubing, or custom designs).
The extruded rubber then passes through a curing or vulcanization process, which hardens and sets its shape. Once cured, the rubber can be cut into specific lengths, coiled, or further processed depending on its intended application.
Extruded rubber products can be custom-made or standard, and come in a variety of shapes and designs. Some of the most common include:
Rubber tubing is widely used in medical, laboratory, and industrial applications. It can transport gases, liquids, or even serve as protective sheathing for wires.
Often used around doors and windows (in buildings and vehicles), these extrusions provide airtight and watertight seals. They block out wind, dust, water, and sound.
Edge trims protect sharp edges of metal, glass, or plastic surfaces while enhancing aesthetics and safety. U-channels fit snugly over edges and are commonly used in automotive or marine applications.
