MOLD SURFACE HEATING USING HIGH FREQUENCY INDUCED ELECTROMAGNETIC PROXIMITY EFFECT

摘要

High frequency induced electromagnetic proximity effect is used to achieve mold surface heating. A pair of flat mold plates (100 mm by 100 mm by 32 mm) was used for the experiments. When a high frequency current flows successively into the two mold plates, an electromagnetic proximity effect is induced between the mold plates and heats the mold surface. Simulation via ANSYS was developed by integration of both thermal and electromagnetic analysis modules. It takes 10s to heat the mold surface from 40°C to 80°C with a heating speed of about 3.68°C/s, and the simulation also shows good agreement with experiments.
