ABSTRACT:
First and second semi-finished molded articles and a third semi-finished molded article are molded simultaneously so as to have joint end faces by using a slide die, a fixed die, and first and second slide cores fitted to the fixed die. The slide die with the third semi-finished molded article remaining thereon is moved toward the first and second slide cores, and their respective joint end faces are registered. Heating surfaces are inserted between the joint end faces. After melting the joint end faces, the heating surfaces are retracted, and the molding device is closed to weld the joint end faces.
