The application of infrared heating lamps in bottle blowing machines has many advantages:
Heating principle and effect
Principle: After the tungsten halogen lamp is heated by a heating element such as a tungsten filament, it emits infrared radiation. Plastic bottle blanks have good absorption characteristics for infrared rays. When infrared rays are irradiated on the bottle blanks, the molecules inside the bottle blanks absorb infrared energy, produce violent vibrations and rotations, thereby achieving rapid heating.
Effect: This heating method enables the bottle blanks to reach the appropriate temperature required for blow molding in a short time, generally only a few seconds to tens of seconds, which greatly improves the production efficiency of the bottle blowing machine compared to traditional heating methods. For example, on some advanced bottle blowing machine production lines, the use of halogen heating lamps can increase production efficiency by 30% – 50%.
