The 369mm 220v 1000w Half-white transparent halogen heating lamp from Goldisgood has several important applications when used with an Automatic Blow Molding Machine:

1. Preheating of the Plastic Preforms
- Enhanced Plastic Softening: In the blow molding process, the first step is often to preheat the plastic preforms. The halogen heating lamp emits infrared radiation that can penetrate the plastic material. This causes the plastic to heat up and become more pliable. The 1000w power of the lamp ensures a sufficient heat output to quickly raise the temperature of the preforms to the optimal range for blow molding. For example, for polyethylene terephthalate (PET) preforms, which are commonly used in making plastic bottles, the lamp can heat them to the right temperature in a matter of seconds to minutes, depending on the specific setup and the number of preforms being processed.
- Uniform Heating: The half-white transparent design of the lamp can contribute to more uniform heating of the preforms. The transparency allows the infrared radiation to spread evenly around the preform, while the white part may help in reflecting or diffusing the radiation to some extent, ensuring that all sides of the preform receive a consistent amount of heat. This is crucial as uneven heating can lead to deformities in the final blown products, such as uneven wall thickness or distorted shapes.
2. Accelerating the Blow Molding Process
- Faster Expansion of the Preforms: Once the preforms are properly preheated, they are more receptive to the blowing air pressure in the blow molding machine. The heat from the halogen lamp makes the plastic softer and more elastic, enabling it to expand more easily and quickly into the desired shape of the final product. This results in a faster blow molding process overall. For instance, in a high-volume production line of plastic bottles, using this halogen heating lamp can significantly increase the production rate by reducing the time taken for each blow molding cycle.
- Energy-Efficient Blowing: The focused heat from the lamp means that less energy is wasted during the heating process. The infrared radiation is directed precisely at the preforms, minimizing heat loss to the surrounding environment. This energy-efficient heating method not only reduces production costs but also contributes to a more sustainable manufacturing process.
