Microwave Preheating Compound Before Extrusion

Microwave Preheating Before Compound for Extrusion

MW preheating of Natural Rubber Bale

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.

MW Preheating of Master Batch

Microwave Preheating Compound for Extrusion

Application Where To Implement Advantages / USPs
Mw – Preheating of Preformcompounds before molding.
  • Preheat the Rubber performs up to 70°C to 90°C
  • With Microwave Preheater before putting into mold.
  • Increase Production capacity of Existing Plants by 30 to 40%.
  • Reduction in molding time saves electricity.
  • Instant start & stop.
  • Easy to operate.
  • Microwave technology heats rubber from inside – out resulting into uniform vulcanization of rubber during molding.
  • Improve material flow ability with in mold resulting in better finish & higher mechanical strength.
  • Improves mold life.
  • Green technology
