Importance of Rubber Extrusion

There are different rubber processing methods but of all the methods, extrusion remains a popular choice for many manufacturers. This is because; extruded rubber products can be produced in a neat, uniform manner. A great variety of shapes can be produced, including hollow designs for any industrial need that greatly reduce material cost and create flexible, lightweight products. Rubber materials are in great demand, making rubber extrusions and molded rubber effective ways to produce these materials.

Verities of Extruded Rubber Products

Extruded rubber products are applied in a wide range of sealing and gasketing applications. They are available in various compounds and styles to meet specific end-use requirements involving various factors like size, tolerance, configuration, cost, and performance. Some extruded rubber products are as follows:

Rubber Bumper

Rubber Bushes

Rubber Cord

Rubber Diaphragm

Rubber Gasket

Rubber Hose

Rubber Shapes

Rubber Stripes and Profiles

Rubber Tubing

The Process of Rubber Extruded Products.

The process of extruding can be compared to squeezing of toothpaste from a tube and the paste takes the shape of the tube opening. The rubber material is processed through an extruder, during the rubber extrusion process. There are two main components of rubber extruders: A small heated drum: As the material enters the drum, it is softened through heating and then pressurized through the rotation of a screw and A die: The pressure pushes the rubber through the die, located at the end of the extruder. Depending on the result desired o Rubber Extruded Products ,pre-heating of the material is optional. The rubber emerges from the extruder in a profile which resembles the die shape. As the possibilities of die design are nearly limitless, so also the number of possible extruded rubber profiles. After being extruded, the rubber material is cured using various methods such as salt bath, autoclave, convection, hot air, microwave and mandrel.
