Induction Heating - Applications - Dielectric Pre-Heating
 

DIELECTRIC PREHEATERS GENERATE HEAT INSIDE MATERIALS ELECTRONICALLY.

Dielectric materials like Bakelite, Urea, Melamine have very few free electrons to conduct heat. When such materials are placed in a high frequency field their molecules start oscillating millions of times each second. Heat is thus generated inside the material in proportion to the applied frequency

 
Benefits of Dielectric Pre-Heating
 
  • Minimizes warpage and shrinkage to improve appearance.
  • Better electrical properties of finished products.
  • Better mechanical strength.
 
Higher Productivity
 
  • Increases production efficiency.
  • Reduces worker fatigue in hand operated presses.
  • Flash thickness can be better controlled.
   
Reduced Costs
 
  • Reduction of moulding cycle time.
  • Reduces rejections.
