ABSTRACT:
Disclosed herein is a method for manufacturing a heating panel. The method comprises preparing upper and lower moulds corresponding to the upper and lower plates, injecting a plastic material into the moulds to produce semi-manufactured products of the upper and lower plates, and bonding the semi-manufactured products of the upper and lower plates to produce the heating panel. The heating panel comprises a uniform fluid pathway formed therein, and allows uniform flow of heating fluid. The heating panel is manufactured by injection molding, thereby preventing blockage of the heating panel to ensure uniform flow of heating fluid. In addition, since the upper and lower plates are formed to a uniform thickness by injection molding, the method of the present invention enables precise forming of the heating panel, thereby allowing a constant tolerance and high quality of the heating panel.
