Hot runner valve gate for eliminating unidirectional molecular orientation and weld lines from solidified resin used for forming molded articles

An injection molding system for processing molten resin to have a substantially homogenized orientation and for molding an article having substantially no weld lines, comprising:

• source means for supplying melt;
• an injection nozzle which receives said melt from said source means, said nozzle including:
• a movable valve stem means for guiding said melt to a molding area, said valve stem means including an input area for receiving said melt, a central area following said input area for processing said melt and an output area following said central area for connection of said nozzle with said molding area, said central area including a first zone means for splitting said melt into a plurality of streams, a second zone means for partially mixing said plurality of streams, and a third zone means for completely mixing said plurality of streams and forming substantially homogenized recombined melt for subsequent direction to said output area;
• and
• a nozzle body portion enclosing said valve stem means;
• means for actuating said valve stem means within said nozzle body portion;
• and
• a mold defining said molding area, said mold adapted to receive said melt from said nozzle for forming an article substantially free of weld lines, wherein said melt is homogenized.
