PROBLEM TO BE SOLVED: To provide a manufacturing method of artificial marble which leaves no bubble within a molding and hardly causes molding deformation and warpage during the manufacturing of the resin molding by using a casting mold. SOLUTION: The method comprises steps for preparing a resin composition 7 by blending a thermosetting resin with a filler, an internal release agent, a curing agent and additives, e.g. a pattern material expressing the pattern of artificial marble, injecting the resin composition 7 into an injection cavity 4 from the injection inlet 2 of a casting mold 1 and hardening the resin composition 7 thermally. The inside surface of the casting mold 1 is hydrophobized preliminarily. COPYRIGHT: (C)2007,JPO&INPIT |
