Things you Need to Know About the Rubber Extrusion Process

Rubber materials have been used by many industries since the 19th century. Since then, different rubber processing methods have emerged but one that remains a preferred choice amongst manufacturers is rubber extrusion.

What does the Rubber Extrusion Process Entail?

Rubber extrusion is the process of turning rubber materials into a specifically shaped product that can be used for various applications.

How does it Happen?

Rubber extruder machines have two main parts; a heated shearing screw conveyor and a die in which the pressurized rubber is squeezed, providing its shape.

During the process, the stock rubber (raw) is processed through the screw. As it turns, the screw pushes the stock while it is heated in the conveyor channel.

From the hopper (container above the conveyor), the stock is sent to the conveyor where it is softened through heating and shearing and pressurized by the screw’s rotation process. The pressurised stock is pushed into the die (located at the end of the extruder) and as it emerges it acquires its shape.

What are the advantages of Rubber Extrusion and Rubber Extruded Products?

A continuous extrusion process can produce finished products in different lengths

Raw materials can be formed into unique profiles with a variety of lengths and shapes

Extruded rubber products or “extrudates” have flexible characteristics and are highly resistant to chemicals and heat
