METHOD AND DEVICE FOR MANUFACTURING BIODEGRADABLE MOLDED OBJECTS

摘要

A molding raw material (9) is heated and swollen by applying a voltage from a power source portion (2) having an A.C. power source for induction heating t o a power feed plate (29) and applying an electric field to a power receiving plate (28), which is out of contact with the power feed plate (29), in a direction crossing the moving direction of a mold (8). This design can preve nt the mold from coming into contact with an electrode and generating arc discharge during heat-molding of a biodegradable molded article by induction heating.
