Abstract
A method and apparatus for virtually eliminating the web-like 'jetting' lines on finished injection molded products by utilizing an expandable cavity which is initially set at a reduced or minimum size to intercept resin flow and disperse it as it enters the cavity, the resin being maintained under pressure within the partially filled cavity, wherein the cavity expands under pressure of the resin flowing therein until the finished size of the end-product is attained.
