A specially designed stand ensures that there is minimum vibration even when operating the extruder at its maximum rated speed. The extruder is powered by a set of standard electric motor and Helical Gearbox, which are properly aligned to provide maximum efficiency.
Temperature Control:
Digital PID Controllers are used in the Control Cabinet to provide an automatic cut-off system that regulates the temperature of the cylinders through the use of good quality heaters and thermocouples. Blowers are additionally provided on extruders requiring more accurate temperature control.
Dies:
The Dies of the extruder are designed according to the specific requirements of the customer. Extruders are manufactured for the following applications:
