ABSTRACT:
A mold gate insert includes a mold gate insert body, which is comprised of a material having a high thermal conductivity, and a thermal insulation element, which is nested in the mold gate insert body. The thermal insulation element is provided to abut a nozzle seal and align the nozzle with a mold gate. The amount of heat transferred from the nozzle to the mold gate insert is reduced by the thermal insulation element.
