A method for reducing the occurrence of voids and areas of porosity in injection molded parts. Vents are placed within the injection mold near areas of the molded part that are prone to the occurrence of voids and areas of porosity. A porous flow regulator is placed adjacent the vents to regulate the flow of the resin near the vent. The flow regulator allows air trapped within the mold to escape through the vents during molding. Allowing air trapped within the mold to escapereduces the occurrence of voids and areas of porosity in the molded part. A porous plug extends through the flow regulator and into the vent. The porous plug prevents excess quantities of resin from flowing out of the vent, thus reducing waste and also helping to maintain the flow regulator in place.
