  • Patent number: 11858188
    Abstract: 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.
