PURPOSE:To obtain a type body of high quality by such an arrangement wherein a heat preserving means is provided between a type molding unit and type holder molding unit in a metal mold for molding a type body and a type face is molded while a difference in temperature is maintained between those units. CONSTITUTION:A heater 5 is provided to correspond to the arrangement of type molding units 3, and in a lower mold 9, a heat pipe 7 is provided for cooling type holder molding units 4. Molding material injected through an injection hole 6 passes through molding units 4 cooled by the heat pipe 7 and flows into the type molding unit 3. Molding material reached the molding units 3 is processed at a high temperature and formed into a type element 1 of high density and molding material injected into the molding units 4 is processed at low temperature and formed into a type holder element which is less in deformation, distortion, warping, etc. |
