Brief description on the main embodiment of energy saving of injection molding machine

    Compared with ordinary plastic processing equipment, the reason why injection molding machines can be widely implemented and applied is inseparable from their powerful energy-saving advantages. So, what are the main aspects of energy saving of injection molding machine equipment? In order to let you have a deeper understanding of this, next, a professional injection molding machine consumer manufacturer, Xiaobian, will explain in detail the main performance of the excellent energy saving of the injection molding machine, hoping to help you in the future.

    The electric heating ring is an essential equipment for heating the barrel of the injection molding machine. Since the injection molding electromechanical heating system accounts for about 15% ~ 30% of the energy consumption of the whole machine, if different varieties of electric heating rings can be reasonably selected, the energy consumption can be reduced, so as to reduce the consumption cost. At present, there are three kinds of electric heating rings popular in the market: resistance electric heating ring, electromagnetic heating ring and nano infrared electric heating ring.

    The resistance electric heating coil needs to restrain the resistance of the conductor, convert electric energy into heat energy, and stop transmission through contact conduction, resulting in a large amount of heat loss to the air, low thermal efficiency and high ambient temperature.

    Electromagnetic heating is generated by LC parallel resonance, and the magnetic line of force is cut through the barrel to generate eddy current to melt the plastic. Electromagnetic heating technology makes the metal barrel heat itself through the principle of electromagnetic induction, and can wrap a certain thickness of thermal insulation materials outside the barrel according to the detailed conditions, which greatly reduces the heat loss and improves the thermal efficiency, so the power saving effect is very significant.

    Nano infrared electric heating ring is generally composed of nano electric heating layer, thermal insulation layer, shell, anti radiation coating and other parts. After AC is connected, the electric heating coil itself becomes a far-infrared radiation heat source, and the heat conversion rate is more than 98%. In addition, the common unidirectional heating design can firmly lock the heat, avoid distribution to the air, and significantly reduce the working ambient temperature. Because the resistance heating ring and infrared heating ring belong to direct heating heating ring, they do not produce harmonics and have no adverse impact on the power grid.

    It can be seen that the energy-saving rate is not the only reference specification for the comprehensive energy efficiency of the electric heating ring, and safety is an important factor that can not be ignored when the injection molding machine enterprise makes the purchase decision. On the basis of electrothermal energy-saving transformation, separating the current advanced servo control technology, the performance of injection molding machine will be a great leap in practice.

    The above is only a brief discussion on the energy-saving performance of the injection molding electromechanical thermosphere, an important component equipment. Of course, the energy-saving performance of the equipment is more than that.
