Rubber Extrusion: The Process
The process of extruding can be compared to squeezing of toothpaste from a tube and the paste takes the shape of the tube opening. 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, 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.

Types of Rubber Extrusion Process
  • Co-Extrusion: This is considered to be a variation of the basic extrusion process. This process allows for the convergence of rubber materials that contain different properties like color and consistency.
  • Cold feed extrusion: This is the process of extrusion without pre-heating. This process is best suited to produce hoses, profiles, cable and sheaths.
  • Hot feed extrusion: This on the other hand is the extrusion process which involves the pre-heating before performing the extrusion process.
  • Pin barrel extruders: This process performs with many pins protruding from the cylinder wall toward the screw's center and enhances the mixing and dispersing of the rubber when it is kneaded between the screws and the cylinder. This method can be applied for diverse applications.
  • Vented extruders: This process has screws of an original and unique design and it is easy to maintain and occupies very little floor space.
Extruded rubber products are used in a wide variety of industries like:
  • Aerospace
  • Automotive
  • Lighting
  • Appliance
  • Electronics
  • Construction and
  • Medical industries
