375mm 400V 2500W Half White Halogen Infrared Heat Lamp for PET Blowing Machine
Halogen semi-white-plated heating tubes have unique advantages and important application value in fully automatic bottle blowing machines. The following is a detailed introduction:
I. Advantages in fully automatic bottle blowing machines
(I) Efficient heating and rapid heating
Enhanced radiation efficiency: The semi-white-plated part of the halogen semi-white-plated heating tube can more effectively reflect and concentrate the infrared rays emitted by the filament to the part of the bottle blank that needs to be heated, thereby increasing the energy density radiated to the bottle blank, thereby speeding up the heating speed of the bottle blank. Compared with ordinary halogen heating tubes, the heating time of the bottle blank can be shortened by about 20% – 30%, greatly improving the production efficiency of the bottle blowing machine.
Quick response characteristics: The halogen heating tube itself has a fast thermal response characteristic, and the semi-white plating treatment does not affect this characteristic, but further optimizes the heat transfer. During the heating process of the fully automatic bottle blowing machine, when the temperature of the bottle blank needs to be quickly increased for bottle blowing operation, the halogen semi-white-plated heating tube can quickly convert electrical energy into thermal energy and transfer the heat to the bottle blank in a concentrated manner, so that the bottle blank reaches the appropriate temperature required for bottle blowing in a short time.
(II) Accurate temperature control
Improved temperature uniformity: The special structure of the semi-white-plated heating tube makes the heat distribution of the radiation more uniform, which can make the temperature rise of each part of the preform more consistent during the heating process. This is crucial for the bottle blowing process, because the uniform temperature distribution can ensure the uniform expansion of the preform during the blowing process, avoid the quality problems such as uneven bottle wall thickness and deformation caused by local temperature differences, and improve the quality stability and consistency of the blown bottle products.
Cooperation with the control system: The halogen semi-white-plated heating tube can work well with the temperature control system of the fully automatic bottle blowing machine. By setting multiple temperature sensors in the heating area, the temperature changes of the preform are monitored in real time, and the signal is fed back to the control system. The control system accurately adjusts the power of the heating tube according to the feedback information, so as to achieve precise control of the temperature of the preform, and the error range can be controlled within a smaller range, meeting the requirements of high-precision bottle blowing process.
(III) Energy saving and cost-effectiveness
Reduced heat loss: The high reflectivity of the semi-white-plated layer can reduce the heat loss of the heating tube to the surrounding environment, so that more heat is concentrated on the heating of the preform. This means that when the same preform heating effect is achieved, less power consumption is required, thus achieving the purpose of energy saving. According to actual tests, compared with the blow molding machine using ordinary heating tubes, the energy consumption of the blow molding machine using halogen semi-white-plated heating tubes can be reduced by about 15% – 20%. In the long term, it can save considerable energy costs for the enterprise.
Reduce maintenance costs: Due to its special structure and material properties, the halogen semi-white-plated heating tube has a long service life. Its semi-white coating can not only improve the heating efficiency, but also protect the filament and other components inside the heating tube to a certain extent, reducing damage caused by high-temperature oxidation, corrosion and other factors. This reduces the replacement frequency of the heating tube, reduces the downtime and maintenance costs of the equipment, and improves the overall operating efficiency and economic benefits of the blow molding machine.
