| Zusammenfassung: | The invention relates generally to the field of injection molding. More particularly, the invention concerns an injection molding method having a pressure relief valve that provides an alternate resin passage for excess molten resin under a predetermined pressure in a non-metallic injection mold.
A method of releasing pressure in a non-metallic injection mold has a pressure relief valve positioned in the molten resin flow path for handling excess resin pressure. The pressure relief valve responds to excess resin pressure in the cavity by providing an alternate resin flow path for the pressurized excess resin. |
