PURPOSE:To manufacture a resin processed product in which sink marks and voids are not generated, deformation is small during the preservation, use and machining and damages are not generated by feeding a molten thermoplastic resin, raising the mold clamping force of a mold and compressing, cooling and solidifying the resin. CONSTITUTION:An example of the molding procedures using a molding device 1 is shown hereby. The mold device 1 is controlled to the temperature proper for solidifying a thermoplastic resin. A given amount of the hot, molten resin 10 is injected into a cavity 9 in the mold through a sprue 8 in a cylinder of an injection molding machine. After that, the mold clamping force is raised and a movable side template 6 is moved, while the molten resin in the cavity 9 is compressed by the given margin for compressing and molded into the shape of the cavity 9, and after the given cooling time is completed, the mold is opened to release a resin material. The material can be manufactured successively by repeating the above-said operation. |
