<p>PROBLEM TO BE SOLVED: To prevent a shortcircuiting from being formed under a state wherein at the time of injection-molding, heating wires are pressed by a strong resin pressure, and bent. SOLUTION: For this method, in a stage wherein a resin is injection-molded in a die 1 comprising an external die and a core 12, a heating wire 3 is embedded in the wall. In this case, a process to prepare a state wherein the resin coated heating wire 3 is wound around the core 12, and a process wherein after forcibly cooling the core part which is confronted with a resin gate of the external mold, or while cooling the core part, the resin is injection-molded in the mold 1, are provided.</p> |
