Abstract
A plastic system for extruding injection molding and extruding a hollow tube from plastic containing heat sensitive material for thereafter forming into a plastic container by blowing including an extruder for melting the plastic and delivering it to an injection system for injecting the plastic into a manifold that delivers the plastic to the tubular cavities of an injection head including providing a static mixer adjacent each of the cavities. By such an arrangement, the plastic flow in each flow channel provides a uniform homogeneous plastic material such that streaks which may be caused by degraded plastic material or by different color material from a previous run are eliminated.
