Abstract
A system for initially separating injection molded plastic parts from the sprue and runner assemblies formed therewith. The system is primarily intended for in situ use with an injection molding machine and includes a hopper-like structure having a supporting surface adapted to receive the plastic product from the molding machine and thereafter effect a separation thereof by means of the sequential operation of first and second barriers preferably within the time frame of a single cycle of the injection molding machine. The parts are delivered to a storage container while the sprue and runner assemblies are granulated.
