Document Type and Number:

WIPO Patent Application WO/2019/004514

Kind Code:

A1

Abstract:

The present invention relates to a heating plate for an electric hair iron and a method for manufacturing the same. More specifically, the present invention relates to a heating plate for an electric hair iron having a soft synthetic resin inserted therein, wherein an aluminum heating plate having a plurality of grooves formed in a longitudinal direction on the front surface is ejected and the soft synthetic resin is inserted into the front surface and both sides of the aluminum heating plate which is in a state of being inserted into a mold such that part of the soft synthetic resin is insertedly integrated into the grooves. The soft synthetic resin is injected from the rear of the aluminum heating plate to the front surface thereof when injecting the soft synthetic resin such that a uniformly even soft synthetic resin layer is formed without generation of bubbles on the front surface by injecting. Accordingly, a hollow through-hole is formed between the grooves of the aluminum heating plate such that heat is uniformly transferred, and a ceramic coating layer is formed inside the groove such that heat is evenly transferred across the soft synthetic resin layer.
