Runner for injection molding

摘要

The invention is directed to the structure of an inline runner (12) for injection molding which uniformly increases the temperature of the injected compound as the compound flows from the injection port to single or multiple drop gates (14) at the entrance to single or multiple injection mold cavities. The inline runner has two opposing series of parallel channels formed into the runner (16) for the purpose of mixing the compound as it flows through the runner (12). <IMAGE>
