Rubber extrusion don’t differs so much of plastic extrusion. Basically, the main difference is the curing process or vulcanization of the rubber during the extrusion process.
As plastic extrusion, in rubber extrusion process the rubber is forced through a die of the desired cross-section under pressure from an extruder. Then, the rubber part normally must be vulcanized before it is usable.
The processes of vulcanization or curing takes place at the last step of the extrusion process. This aids the rubber extruded profiles to maintain its shape and acquire necessary physical properties.
Exist different types of rubber extrusion processes:
Continuous in-line cure extrusion: The rubber material travels through a curing tunnel that raises the product to the appropriate vulcanizing temperature.
Off-line cure extrusion: The warm rubber is driven through the die and then exposed to high-pressure steam in order to achieve the appropriate vulcanizing temperature.
Huge variety of shapes.
Flexible and lightweight products.
Minimal wasted material.
Highly efficient process.
