Title: HEATING STRUCTURE
Abstract:
Provided is a heating structure, which is used for manufacturing automotive parts requiring plastic injection molding, the heating structure comprising: a base material for injection molding made of an injectable polymer; a conducting material mixed with the base material for injection molding and having conductivity; and a metal material mixed with the base material for injection molding and the conducting material, and having a heating function upon application of electric power. Accordingly, it is possible to improve durability by not using a heating member such as a hot wire and the heating structure can generate heat by itself when power is applied. As such, when the heating structure is applied to a lamp which is a plastic injection molded part of a vehicle, the temperature of inboard and outboard sides of the lamp can be easily raised to easily prevent moisture from being generated in the lamp.
