Abstract

PURPOSE:To provide a molded product having a smooth surface by a method wherein an injected resin is heated by a heating means arranged in a screw of an injection machine, resin at the bottom of groove in the screw which is easily stayed is made to be slid and moved to a cylinder. CONSTITUTION:Resin 6 fed into the hopper 1 is moved in sequence toward a melting part C from a feeding part A by a screw 2. Since a heating means 7 is arranged in the screw 2, the resin 6 is heated from a cylinder 3 and the screw 2, softened and melted, and at the same time the resin 5 contacting with the cylinder 3 is pushed in a direction opposite to that of the injection direction by a reaction force of the advancing flow, so that the resin 5 at the bottom of the groove in the screw 2 is flowed in a direction indicated by an arrow to make a rotary flow. Self agitating of the resin may cause a melting of nonmelting resin 6 to be promoted, a surface of the injection molded product may not show any cracks or rough surface even if the screw 2 is operated under a high speed, and thereby an injection molded product having a uniform quality may be made.
