ABSTRACT:
A heater is incorporated in a pointed conical heat-generating means fixed with a projectile heat-generating body. The heater is a ceramic columnar body having a heat resisting and insulating property. Disposed within the ceramic columnar body is a coiled heating wire of which winding diameter is formed as small as possible. Due to discontinuous energizing process of the heater, thermoplastic synthetic resin adjacent a gate can be heated and fused, or cooled and solidified intermittently, thereby the gate communicated with a cavity can be opened or closed effectively.
