EXPANDED POLYSTYRENE PATTERN REMOVAL METHOD IN FULL MOLD PROCESS

摘要

PURPOSE: An expanded polystyrene pattern removal method in full mold process is provided to separate easily a molding plane from a foam polystyrene pattern by electric heating. CONSTITUTION: An expanded polystyrene pattern(200) removal method in a full mold process is as follows. The electrically resistive coating layer is formed in a foam polystyrene pattern. The foam polystyrene pattern is molded. Electricity is supplied to the electrically resistive coating layer to transform the foam polystyrene pattern and then to remove it.
