Halogen infrared heating tubes play an important role in fully automatic bottle blowing machines and have many advantages. The following is a detailed introduction:
- Heating principle and characteristics
Heating principle: Halogen infrared heating tubes heat the filament to a high temperature by applying current to the filament. The halogen gas around the filament reacts chemically with the evaporated tungsten to form tungsten halides, which decompose near the filament and are redeposited on the filament, extending the life of the filament. At the same time, the infrared radiation energy generated by the heating of the filament can efficiently heat the preform.
Radiation characteristics: The infrared wavelength range emitted by halogen infrared heating tubes is relatively wide, of which medium-wave infrared accounts for a large proportion. Medium-wave infrared has a strong penetrating ability and can penetrate deep into the interior of the preform, so that the inside and outside of the preform are heated at the same time, and the heating is more uniform and rapid. - Practical application cases and effects
Beverage bottle production: On the beverage bottle blowing production line, the fully automatic bottle blowing machine using halogen semi-white-plated heating tubes can efficiently heat and blow PET preforms. Its fast heating capability and precise temperature control ensure the quality and production efficiency of beverage bottles. For example, when producing 500ml PET beverage bottles, the hourly output can be increased by about 10% – 15%, while the uniformity of the wall thickness and the appearance quality of the bottles have been significantly improved, meeting the needs of large-scale, high-quality beverage bottle production.
Cosmetic bottle production: For the production of products such as cosmetic bottles that require high appearance quality and precision, the advantages of halogen semi-plated white heating tubes are more obvious. Through its uniform heating characteristics and precise temperature control, the blown cosmetic bottles can have a smooth, flawless surface with high shape and size accuracy. This not only increases the added value of the product, but also enhances the competitiveness of the product in the market, providing cosmetic companies with high-quality packaging solutions.
