435mm 240v 1300w Clear Halogen Ir Heat Lamp Heating Elements For For PET Blowing Machine Goldisgood
Application in PET Blowing Machine
Softening the PET Pre – form: PET blowing involves taking a pre – formed tube – like structure of PET and inflating it to form a bottle or a container. Before inflation, the pre – form needs to be softened. The heat lamp provides the necessary thermal energy to raise the temperature of the PET to its glass – transition temperature range (around 70 – 100°C depending on the grade of PET). At this temperature, the PET becomes pliable and can be easily blown into the desired shape.
Uniform Heating: The combination of halogen and IR heat helps in achieving uniform heating of the PET pre – form. Uniform heating is crucial because any cold spots or unevenly heated areas can lead to defects in the final blown product such as thin – walled regions, warping, or improper shape formation. The 435mm length of the lamp and its heat distribution characteristics play a vital role in ensuring that the entire pre – form is heated evenly.
Energy Efficiency: The 1300W power output is designed to provide efficient heating for the PET blowing process. By quickly heating the PET pre – form, the overall energy consumption can be optimized as the machine doesn’t have to run the heating element for an extended period. This also helps in increasing the production rate of the PET blowing machine.
