PURPOSE: A method for manufacturing a PTC(positive temperature coefficient heater) heating element is provided to continuously manufacture a PTC heating element with improved heating performance and lifetime properties by using a polymer composition including a molten polymer composition material and a conductive material and a surface-processed electrode conductor processed. CONSTITUTION: Solution including graphite(20) is coated on a pair of circular electrode conductors(10) arranged at a predetermined space. A polymer composition including Polymer resin, carbon block, and an additive is adhered on the electrode conductors. A PCT heating body(30) is pressure-molded in order to cover the electrode conductors. A pressure-molding processes under a condition of 100bar-400bar. An insulation cladding(40) is formed in outside of the PCT heating body. |
