A system for producing blow molded articles. The system includes an injector nozzle mounted to a parison cavity block having a parison cavity such that the injector nozzle injects molten plastic into the parison cavity to form a parison. The injector nozzle is mounted to the parison block by means of two seats, a distal seat where the distal end of the injector nozzle is seated within an opening in the parison cavity block and a proximal seat, a linear distance inwardly from the distal seat, where a circular flange on the injector nozzle is seated within an annular shelf formed in the parison block. The two spaced apart seats ensure an accurate alignment between the centerline of the injector nozzle and the parison cavity. As a further feature, there is a system to heat the nozzle tip to reduce the temperature differential between the nozzle and the parison cavity.
