A runner system and runner component particularly adapted for use in multiple cavity injection molding systems is disclosed. The runner system and runner component utilize particular structural features and geometrical configurations that have been found to result in superior molding practices and molded components in multiple cavity injection molding systems. A corresponding multiple cavity injection molding system utilizing the noted runner system is described. And, a related method for promoting uniform filling of multiple mold cavities is also disclosed.

Apparatus for multiple cavity injection molding

In a method of feeding a plastic material to a using apparatus such as a molding press or an extruder, a moldable or extrudable plastic material in elongated strand form is provided. The moldable or extrudable plastic material is arranged such as in a package comprising a plurality of convolutions. The package is supported adjacent to the using apparatus and successive increments of length of the elongated strand material are payed out and fed into the using apparatus.
