3. Installation position；
The outer diameter measurement and control instrument can be installed either before or after the cooling water tank. When it is installed in front of the water tank, since the measuring head is close to the extruder and the feedback control is timely, the best control effect can be obtained, but the plastic has not been cured, the set nominal value should be corrected appropriately. When installed behind the water tank, the actual value of the cable outer diameter is measured, which is more accurate and reliable, but the control lag is large and the control effect is slightly poor. In addition, it should be noted that the measured cable should be blown dry, otherwise the water film outside the cable will affect the measurement accuracy. In actual use, the nominal value should be appropriately increased according to the degree of water carried by the measured object.
