The following are some applications of 320m 660mm 220v 230v 2000w SK15 Clear/Half White Plated Halogen Infrared Heat Lamp in plastic molding:
Mold preheating
Improve molding efficiency
Before plastic molding processing, use this halogen infrared heat lamp to preheat the mold, so that the mold can quickly reach the appropriate working temperature. For example, for some large or complex molds, the traditional preheating method may take a long time, while this infrared heat lamp can provide enough heat in a short time, thereby shortening the mold preheating time, improving production efficiency, and reducing the downtime waiting time of the equipment.
The appropriate mold temperature helps the flow and filling of the plastic melt in the mold, making the molding process smoother, reducing the viscosity of the melt, reducing the flow resistance of the melt in the mold, avoiding molding defects such as short shots and flash, and improving the one-time molding pass rate of plastic products.
Improve product quality
Preheating the mold can make the mold surface temperature evenly distributed, avoiding shrinkage marks, deformation, stress concentration and other quality problems of plastic products caused by local temperature being too low or too high. The uniform heating of the infrared heat lamp can ensure the temperature consistency of each part of the mold, so that the dimensional accuracy and appearance quality of the plastic products are effectively guaranteed.
For some temperature-sensitive plastic materials, such as PVC, it is particularly important to accurately control the mold preheating temperature. The heat lamp can accurately preheat the mold to the required temperature by adjusting the power and irradiation time, etc., to prevent the material from decomposing or deteriorating due to excessive temperature during the molding process, and ensure the stable performance and reliable quality of the plastic products.
Plastic melt heating
Promote uniform mixing of the melt
In processes such as plastic injection molding or extrusion molding, the infrared heat lamp is applied to the heating link of the plastic melt, so that the melt can be heated more evenly in the pipe or barrel. During the heating process of the melt, the movement of the molecular chain is more active, which helps to better mix plastic melts of different batches or different components, improve the uniformity of the melt, and make the performance of the molded plastic products more consistent.
When some additives are added to the plastic melt, such as masterbatch, antioxidants, etc., the heating of the infrared heat lamp can promote the uniform dispersion of the additives in the melt, ensure the stability and consistency of the color and performance of the plastic products, and avoid appearance defects or performance problems caused by uneven dispersion of additives.
Reduce melt viscosity
Heating the plastic melt can reduce its viscosity, making it easier to flow and form. The halogen infrared heat lamp can provide enough heat to reduce the viscosity of the melt to a suitable range, which is convenient for filling and molding in the mold. For some high-viscosity plastic materials, such as PPO, PC, etc., reducing the melt viscosity is crucial for smooth molding. By using this heat lamp, the molding and processing performance of these materials can be effectively improved.
