Method and apparatus for producing biodegradable molded article

摘要

The moulding 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 to 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 mould (8). This design is said to be able to prevent the mould from coming into contact with an electrode and generating arc discharge during heat-moulding of a biodegradable moulded article by induction heating.
