PROBLEM TO BE SOLVED: To maintain strength and to enable integral molding by arranging a plurality of injection ports in a molding machine and providing at least one sliding part in a mold. SOLUTION: As injection in the first step, an injection cylinder 5 is actuated, and for example, molten magnesium of the first raw material is packed from an injection port 9 into a cavity 3 and solidified to obtain a molding 4. When a temperature sensor 16 set in a mold indicates a set value, a signal (a) is sent to a control part 17, the control part 17 sends a signal (e) to a cylinder 13 to form the cavity, the second raw material is supplied from a molten metal supply port 14 to an injection port 10 by a signal (d) with a partially sliding mold 12 retracted and injected to mold a molding 22. The integrally molded molding 4 and the molding 22 are pressed to a movable mold 1 by the cylinder 5 and moved while being held by the movable mold 1, a mold 26 is separated by an inclined pip and a groove, an injection gate 24 is demolded and discharged by an ejector pin. In this way, a strong, tough molding can be obtained from simple substance structures having opposite properties by using the materials of both.
