ABSTRACT:
This invention reduces the time that a core rod must remain at an injection station of a plastic blow molding machine. The injection operation is usually performed by a plasticizer, and while the injection operation itself requires very little time, the plasticizer performs other roles that must be complete before the next injection. This invention uses two plasticizers alternately so that one can inject while the other recovers for its next injection operation. A plastic pump is used to relieve the plasticizers of some of the operations that they previously performed.
