Infrared heating lamps are used in PET molding machines
1. Accurate temperature control
Sensitive temperature regulation: Infrared heating lamps are sensitive to the temperature control system. During the injection molding process, different plastic materials and product shapes have precise and different temperature requirements. Infrared heating lamps can accurately adjust the output power according to the temperature control instructions of the injection molding machine to achieve precise control of the barrel temperature. For example, when injecting high-precision plastic parts, the temperature control accuracy can reach within ±3℃, ensuring that the plastic is injected at the appropriate temperature and improving product quality.
Stable temperature output: During the continuous injection molding production process, infrared heating lamps can maintain stable temperature output. It will not experience temperature fluctuations due to aging of heating elements or environmental factors like some traditional heating methods. This stable temperature environment helps to ensure the uniformity and fluidity of the plastic melt, making the quality of the injection molded products more stable, such as the dimensional accuracy and appearance quality of the product can be effectively guaranteed.
2. Improve product quality
Uniform heating of plastic melt: The infrared heating lamp has good heating uniformity. It can make the plastic particles in the barrel evenly heated to form a uniform plastic melt. During the injection molding process, uniform melt can better fill the mold cavity and avoid product defects caused by uneven melt temperature, such as short shots, flow marks, shrinkage marks, etc. For example, when injecting a large plastic shell, it can ensure that the wall thickness of each part of the shell is uniform and the appearance quality is good.
Reduce material degradation: Due to its precise temperature control and uniform heating characteristics, infrared heating lamps can prevent local overheating and degradation of plastic materials in the barrel. The degradation of plastic materials will affect their performance, such as reducing mechanical strength and changing color. Using infrared heating lamps can effectively reduce the occurrence of this situation and ensure that the performance of injection molded products meets the requirements.
