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.
