An injection apparatus is configured to feed a molten resin into an injection molding section of an injection stretch blow molding machine. The injection apparatus uniformly melts a resin material while the duration from the time of starting plasticizing and kneading till completion of injection is shortened, thereby allowing the operation of the injection apparatus to fall within the time corresponding to the reduced injection molding process in the injection stretch blow molding machine. Thus, the molding cycle for a hollow body is reduced. In this context, at the start of the filling for each injection cycle, the injection apparatus starts plasticizing and kneading for generating the molten resin for injection in the next injection cycle.
A method for injecting a molten resin by an in-line screw type injection apparatus configured to perform filling, holding pressure, and metering, the method comprising injecting a molten resin by rotating and advancing a screw, which has been positioned in an injection start position, for filling, and holding pressure and metering while rotating the screw continuously from the filling, which are performed in this order as an injection cycle, wherein
An injection apparatus configured to inject a molten resin, being an in-line screw type injection apparatus configured to perform filling, holding pressure, and metering, the injection apparatus operating in an injection cycle in which injecting a molten resin by rotating and advancing a screw, which has been positioned in an injection start position, for filling, and holding pressure and metering while rotating the screw continuously from the filling are performed in this order, wherein
