Abstract

An apparatus for injection molding of non-precatalyzed resins. Catalyst and resin flows are injected into a mixing chamber through a pair of catalyst injection nozzles and a pair of resin injection nozzles, each angled toward the ejectment end of the mixing chamber. The resin injection nozzles are located closer to the ejectment end of the mixing chamber than the catalyst injection nozzles. The injection nozzles are arranged substantially 90.degree. from one another with the resin injection nozzles opposed from each other and the catalyst injection nozzles opposed from each other.
