PROBLEM TO BE SOLVED: To provide a method for molding resin with no need of employing molding material molded into tablets, and with the capability of obtaining molded articles having small void failures. SOLUTION: The resin molding method is to inject particulate molding material 2 supplied in a pot 1 from the port 1 to a cavity 4 by an injection plunger 3, in which, at first, the molding material 2 is compressed by clogging circulation from the pot 1 to the cavity 4 and pressurizing molding material 2 within the pot 1 by the plunger 3. Following this, buy opening circulation from the pot 1 to the cavity 4 and pressurizing the molding material 2 within the pot 1 by the plunger, the molding material 2 is injected into the cavity. As such, air among particles of the molding material 2 supplied into the pot 1 is expelled, then molding can be done for injecting the molding material 2 into the cavity 4. |
