PROBLEM TO BE SOLVED: To secure a satisfactory appearance quality while performing continuous molding production in a short molding tact even in moldings with any appearance shape.SOLUTION: By making a composition where a high pore diameter range 8 is provided between the surface 2 of a cavity and an electrothermal heater 7, the electrothermal heater 7 can be arranged so as to be made close to a cooling circuit 9, and, since the cooling of the electrothermal heater 7 can be efficiently performed while securing the heating efficiency of the cavity surface 2 by the high pore diameter range 8, even in moldings with various shapes, while performing continuous molding production with short molding tact, satisfactory appearance quality can be secured.SELECTED DRAWING: Figure 1 |
