초록

The plastic extruder assembly is of the type that includes an extruder barrel assembly and an extruder die chamber in the distal end of the extruder barrel assembly. The die chamber has means for receiving and mounting a die assembly therein and the die assembly has die holes extending therethrough to an outer face. A layer of insulating material is provided beneath the outer die face at least in the area of the die holes for inhibiting if not altogether preventing freezing of the plastic in the die holes. Also, radial and circumferential hot oil passage...
