DEVICE FOR STRETCH BLOW MOLDING AND METHOD FOR PRODUCING PREFORMS

摘要

In a device for the stretch blow molding of plastic containers in a continuous single-stage process, at least one injection rotor is provided with injection molds for preforms, which are fed via controlled valves from an extruder head and by way of a melt distributor from a central extruder, wherein the axis of the extruder is placed at least substantially in the axis of the injection pipe, and at least the extruder head and the melt distributor can be permanently and synchronously rotationally driven by the injection rotor. According to the method, during the production of each preform in the injection mold injection molding phases and a compression molding or post-pressing phase are combined and superimposed.
