1. Role in PET Bottle Blowing Process
    • Heating the PET Preforms: In a PET bottle blowing machine, the first crucial step is to heat the PET preforms to a suitable temperature range. The 10V 500W round-shape halogen heating lamp plays a vital role in this. When electricity is passed through the lamp, the tungsten filament inside heats up and emits infrared radiation. The PET preforms are placed in the vicinity of these lamps, and they absorb the infrared radiation.
    • Softening the PET Material: The absorbed infrared radiation causes the PET molecules to gain kinetic energy. As a result, the temperature of the PET preforms rises, and the material softens. This softening is essential as it allows the preforms to be stretched and molded into the shape of a bottle during the subsequent blowing process. Without proper heating and softening, the PET would not be pliable enough to take on the desired bottle shape.
  2. Advantages in PET Bottle Blowing Application
    • High Heating Efficiency: Halogen heating lamps are known for their relatively high heating efficiency. The infrared radiation they emit can penetrate the PET preforms to some extent, heating them from the inside as well as the outside. This volumetric heating effect means that the PET preforms can be heated to the required temperature more quickly compared to some other heating methods. Faster heating leads to increased production speed in the PET bottle blowing machine, allowing for more bottles to be produced in a given time period.
    • Precise Temperature Control: The power output of the 10V 500W lamp can be adjusted in some setups. By controlling the voltage or current supplied to the lamp, the intensity of the infrared radiation can be regulated. This precise control over the heating is crucial in the PET bottle blowing process. Different PET formulations or bottle designs may require specific heating temperatures, and being able to accurately control the lamp’s output ensures that the PET preforms are heated to the exact temperature needed for optimal blowing and bottle quality.
    • Compact and Uniform Heating: The round shape of the lamp helps in providing a more or less uniform heating pattern around the PET preforms. When multiple lamps are arranged in a proper configuration, they can evenly heat the preforms from all sides. Additionally, the relatively compact size of the lamp makes it suitable for fitting into the space available in the PET bottle blowing machine setup without taking up excessive room.
