Microwave Preheating Before Compound for Extrusion
The rubber extrusion process is one of the most power-demanding processes in the rubber industry. The extrusion process is what brings about the final shape of the product. Instead of directly resorting to extrusion, preheating with a microwave heating technology can give rise to multiple benefits.
Preheating of rubber compounds enables smoother operation during the extrusion process and also results in better end-product quality. The conventional heating process alters the physical properties of the material to some extent. However, microwave preheating is a quick process that doesn’t alter the essential physical attributes of the rubber compound.
- Heats the rubber strip in a uniform way for the feeding.
- Gives you more control over the extruded profile due to the increased flow of the material.
- Electrical controls enable operators to feed the material from afar.
- Reduces the need for excessive loads to extrude the material into the desired shape.
