The role of infrared heating lamps in bottle blowing machines:
Preheating preforms
Principle: The IR Heat Lamp in bottle blowing machines mainly heat preforms by emitting infrared rays. Infrared rays are a type of electromagnetic wave. The molecules in the preform material (such as PET plastic) can absorb the energy of infrared rays, thereby intensifying the vibration and rotation of the molecules and realizing the conversion from electromagnetic energy to thermal energy. This heating method is a non-contact heat transfer, which can transfer heat to the preform more quickly and evenly than traditional contact heating.
Effect: In the bottle blowing process, the preform needs to be heated to the appropriate softening temperature before it can be blown.Replacement Infrared Halogen Lamp can accurately heat PET preforms to about 100-120℃. This temperature range helps the molecular chain of the preform material to relax, so that the preform reaches a suitable blowing state, laying a good foundation for subsequent bottle blowing operations.
Ensure the quality of bottle blowing
Uniform heating: Uniform heating is crucial to the quality of bottle blowing.Replacement Halogen PET blowing machine can irradiate the preform from multiple angles, and can ensure that all parts of the preform are heated evenly by adjusting the position and angle of the lamp and the design of the reflector. When the preform can get balanced heat in both the circumferential and axial directions, the thickness distribution of the bottle wall will be more uniform during the blowing process, effectively reducing the phenomenon of local thinness or thickness of the bottle, thereby improving the physical properties and appearance quality of the bottle.
Reducing defects: Appropriate heating can prevent the preform from cracking, deformation and other defects during the blowing process. Infrared heating lamps can provide a stable heating temperature to avoid quality problems of the preform due to too high or too low temperature. For example, if the temperature is too high, the preform may be over-softened and unable to maintain its shape during blowing; if the temperature is too low, the preform may not be fully softened, resulting in blowing failure or the transparency, pressure resistance and other indicators of the bottle not meeting the requirements.
Improve blowing efficiency
Fast heating characteristics:Long lifespan Halogen quartz lamp have the characteristics of fast heating, which can heat the preform to the required temperature in a shorter time. Compared with traditional heating methods, it reduces the heat conduction and heat convection time during the heating process, and the preform can directly absorb infrared energy to achieve rapid heating. This is particularly important on large-scale blow molding production lines. For example, in the high-speed production of beverage bottles, the use of halogen light bulb can increase the overall production speed of blow molding by 30% – 50%, greatly improving production efficiency and meeting the needs of a large number of product packaging.
Shorten the production cycle: Rapid heating of the preform also means shortening the blow molding cycle. In the production process, the time reduction of each link can have a positive impact on the overall production efficiency. Moreover, efficient heating can also reduce the production cost per unit product because more qualified products can be produced in the same time.
Energy saving and consumption reduction
Efficient energy conversion: The halogen quartz heating tube has a high heating efficiency. It can efficiently convert electrical energy into infrared radiation energy and accurately transfer energy to the preform, reducing the loss of energy in the surrounding environment. This is because infrared rays act directly on the preform, avoiding the energy loss in the process of heating the surrounding air first and then transferring heat to the preform through the air, as in traditional hot air heating.
Reduced energy consumption: Due to its rapid heating characteristics, the heating task is completed in a shorter time, which also reduces the overall energy consumption. Energy saving is an important consideration in the daily production of the blow molding plant. The use of IR Heating Element can save about 20% – 30% energy compared to traditional heating methods such as hot air heating, which can significantly reduce energy costs in the long run.
