Abstract

본 발명은 세라믹예열플러그의 발열세라믹팁제조방법에 관한 것으로, 펀치조정공정과 발열코일장입공정, 세라믹가압공정, 및 열간가압소정공정으로 진행시켜, 세라믹분말성형체제조와 발열코일의 매립을 단일공정화함과 더불어 발열코일의 매립위치를 정밀하게 제어할 수 있도록 된 것이다.The present invention relates to a method for manufacturing a heating ceramic tip of a ceramic preheating plug, and proceeds to a punch adjusting step, a heating coil loading step, a ceramic pressing step, and a hot pressing predetermined step, thereby producing a ceramic powder molding and embedding the heating coil in a single step. In addition, it is possible to precisely control the embedding position of the heating coil.
