The significance of regulating the temperature of preforms
The temperature of preforms refers to the temperature of the preforms when heat flows through them during the production process. Regulating the temperature of preforms is an important guarantee for production and can affect the performance and output of the product. Correctly regulating the temperature of preforms can not only improve production efficiency, but also improve product quality and reduce production costs.
Methods and precautions for regulating the temperature of preforms
1. Methods for regulating temperature
(1) Temperature regulation in the front zone: Increasing the temperature in the front zone can increase output and reduce product defect rates.
(2) Temperature regulation in the middle zone: Regulating the temperature in the middle zone affects the mechanical properties and heat resistance of the product and needs to be reasonably adjusted according to product requirements.
(3) Temperature regulation in the back zone: The temperature in the back zone is generally set at the average of the front and middle zones. Too high or too low will affect the physical properties of the product.
2. Precautions
(1) The temperature of the preforms needs to be reasonably adjusted according to product requirements.
(2) The temperature of the preforms should be stable and should not fluctuate too much.
(3) The preform temperature should not be too high or too low and should be controlled within the appropriate range.
(4) The preform temperature adjustment should be corrected in time to avoid production accidents.
