摘要： A coil surrounding only the tip of nozzles of a plastic extruding die is provided. By passing a high frequency current through the coil to selectively heat only the tip of the nozzles. Further, in a plastic extruding die in which a high frequency current is passed through a coil provided around nozzles to heat the periphery of the nozzles, the coil is formed of a conductor tube through which a coolant is caused to flow.
