Definitions

  • a new method and apparatus are provided for delivering sequential shots of polymer materials to multiple mold cavities to form multilayer articles. It has been found that selective use of shooting pots can produce multilayer structures with substantially different weight percentages of layer materials but a relatively uniform layer structure, across multiple cavities.
  • an injection molding apparatus comprising:
  • FIGS. 4A-4D illustrate a three-shot multilayer injection molding process for forming the five-layer, three-material preform of FIGS. 2A-2B .
  • the preform is formed in a mold cavity 466 between an outer mold 303 and inner core 302 of a conventional injection mold.
  • a first shot of first polymer material 318 is injected into a proximal end (gate) of a mold cavity 466 and as it flows through the mold cavity, due to the relatively cool temperatures of the outer mold 303 and inner core 302 , there will be solidification of the first polymer material on both the inner and outer walls of the mold cavity/core to define exterior inner 304 and outer 306 preform layers (layers 132 and 134 in FIG. 2B ) of the first material.
  • the first shot of virgin material is delivered from the metering pot 36 through a central axial bore 460 in the nozzle 468 .
  • the controller 28 instructs the actuator 400 to retract the valve pin 450 to the position shown in FIG. 7B where the tip end of the central bore 460 is opened and material flow through central bore 460 into gate 464 of cavity 466 is enabled.
  • cavity 466 begins to fill in the manner and profile shown schematically in FIG. 4A .
  • the controller instructs the actuator 400 to move the pin 450 to the position shown in FIG. 7C to close the central axial bore 460 (feeding the first shot material) and enable flow of the second material through nozzle bore 462 .
  • the controller 28 instructs either valve 40 to open or screw 34 to operate (or both) in order to coordinate the start of the flow of the second material with the opening of nozzle bore 462 .
