ABSTRACT:
The present invention is directed to a method and an apparatus for forming glass articles from molten glass involving differentially cooling a plunger for press forming glass articles in a cooperative forming mold. More specifically, the method involves introducing cooling fluid into an inlet cooling cavity located in the upper portion of the plunger and causing the cooling fluid to flow from the inlet cooling cavity into a cooling passage located along the periphery of the nose portion and thereafter to flow into a outlet cooling cavity located in the upper portion of the plunger and thereafter exhausting the spent cooling fluid from the plunger.
