This production line is composite of extruder, machine head, cooling sizing mould, heat-insulating plate, braking device, cutting machine, bracket, etc.
Usually the extruder screw diameter is cp45-90mm. It is mainly based on the bar diameter to select the extruder model. Meanwhile, it is better that the extruder screw diameter is smaller than the bar diameter for easy extruding operation. For example q>45 extruder can produce bar of diameter
