Why Silicon is Preferred by Rubber Extruder Manufacturers
Silicone rubber extrusion is a continuous process utilized by Rubber Extruder Manufacturers in which a catalyzed compound (usually continuous strips) is introduced into a feed system via a screw that transports the material to a nozzle. Pressure and temperature increase near the die to achieve the required viscosity. The screw is a key mechanism in the extruded rubber process as it feeds and pushes the material against the flow so that it enters the die correctly. Again, the screw plays a key role in exiting the rubber silicone die, ensuring the quality and regularity of the profile being produced and preventing unwanted bubbles or unevenness in the final product. This is done by changing the screw geometry, speed, pressure and temperature, and other mechanical parameters. The profile then passes through an oven that hardens the part. There are different types of ovens or furnaces to carry out the healing process, mainly to suit the different catalysts used in the composition.
