摘要： A preplasticizing type injection apparatus comprising an injection cylinder (12) internally provided with an injection plunger (10) and a plasticizing cylinder (22) provided in the inside with a plasticizing screw (20) or plunger, said injection and plasticizing cylinders (12,22) being arranged in juxtaposition and held in communication with each other by way of a resin conduit (3) connecting an inlet path (15) of the injection cylinder (12) arranged at the front end thereof and defining the limit of advancement of the plunger (10) and an outlet path (21) of the plasticizing cylinder (22) arranged at the front end thereof so that a front end portion of the injection cylinder (12) is charged with resin molten in the plasticizing cylinder (22) and the resin in the front end portion of the injection cylinder (12) is injected into a mold by means of the plunger (10), characterized in that the resin conduit (3) is realized in the form of a small metal pipe having an inner diameter between 5 and 10 mm and a length at least five times and preferably twenty to forty times greater than the inner diameter of the pipe and provided on the outer periphery with temperature control means (31) is provided. With such a conduit (3), resin passing therethrough can be more kneaded to improve the distribution of heat and plasticity before it gets to the injection cylinder (12).
