What Is Rubber Extrusion?
Rubber extrusion is a manufacturing process where specially formulated rubber compounds are forced through a precision-engineered die to create continuous rubber profiles with a consistent cross-sectional shape.
Unlike molded rubber products, extruded rubber components can be produced in virtually unlimited lengths, making them ideal for sealing, insulation, vibration control, and edge protection.
After the rubber exits the extrusion die, it passes through a curing process known as vulcanization, which enhances strength, flexibility, durability, and resistance to harsh environmental conditions.
