Abstract
Coinjection molding system control apparatus and method preferably includes flow control structure and/or steps configured to reduce pressure on a second melt, preferably causing a relatively small portion of a first melt to flow from a distal portion of a first melt channel in the coinjection nozzle into a distal end of a second melt channel in the coinjection nozzle. This prevents substantial amounts of the second melt from being dragged into the mold cavity when the next shot of the first melt is injected.
