The injection nozzle includes a longitudinal flow channel, a plurality of angular channels extending from the longitudinal flow channel (1) in a first direction at an acute angle with respect to the longitudinal axis of the nozzle, and (2) in a second direction at an acute angle with respect to the first direction, an annular channel extending from the angular channels, and a passageway extending from the annular channel to the injection orifice, wherein the angular channels cause a swirling action in the annular channel to flush out resin from the annular channel.
