摘要 |
A method for manufacturing a long molding having an axial bend, includes: forming a long first member; performing an axial bending process for the first member, when the first member passes through a gripping portion; and extruding a heated and molten liquid resin molding material for formation of a second member through a second member molding opening of a second member extrusion die while following a bend of the first member to integrate the second member made of the molding material with the first member. The second member extrusion die has a changeable substantial opening shape of the second member molding opening. The second member having a different cross sectional shape between one part and the other part in the longitudinal direction is extruded in accordance with a change of the opening shape.
