In the plastics industry, infrared thermometers can be used to measure the temperature of dynamic objects and plastics to avoid product tarnishing. In the blown film spraying process, in order to maintain the integrity of the plastic and the thickness of the temperature should be strictly controlled, then the infrared thermometer can monitor the temperature, so that operators to adjust the heating and cooling. Infrared thermometers can also be used to measure the temperature during the ejection of thrown film. When the film is pressed out, the temperature value measured by the infrared thermometer allows the operator to adjust the heater and the cooling roll to ensure the quality of the product.
