Here are some common applications of the 478mm 230v 2000w SK15 semi-white coated halogen infrared heating lamp for plastic molding:
Mold preheating
Mold preheating is a very important step in the plastic molding process. This heating lamp can be used to preheat plastic molds. The infrared rays it emits can penetrate the mold material and quickly reach the appropriate temperature. By preheating the mold, the fluidity of the plastic in the mold can be improved, allowing the plastic to fill the mold cavity more evenly, thereby improving the molding quality of plastic products and reducing molding defects such as lack of material and shrinkage caused by low mold temperature.
For example, for some large or complex plastic molds, after fully preheating with this heating lamp, the plastic can better conform to the shape of the mold when injected into the mold, ensuring that all parts can be fully filled and improving the qualified rate of the finished product.
Plastic material preheating
In addition to mold preheating, it can also be used to preheat the plastic material to be injected into the mold. The heat from the heating lamp can make the plastic particles or plastic raw materials reach a certain temperature before entering the mold, so that after being injected into the mold, the plastic can flow, fuse and form faster in the mold. This is especially important for some plastic materials that are sensitive to temperature, such as some engineering plastics. By preheating the plastic material, its viscosity can be reduced, its plasticity can be improved, and the molding effect and quality of plastic products can be improved.
For example, when producing some high-precision plastic parts, after preheating the plastic material, the molding process of the plastic in the mold can be more accurately controlled, and plastic products with higher dimensional accuracy and better surface quality can be obtained.
Accelerate the molding process
Since the heating lamp can effectively heat the mold and plastic material at the same time, this greatly speeds up the entire plastic molding process. In the traditional plastic molding process, the mold and plastic material may take a long time to naturally heat up to the appropriate state. After using this heating lamp, the heating time is greatly shortened, thereby improving the production efficiency of plastic molding.
Taking the injection molding process as an example, the use of this heating lamp can significantly shorten the injection molding cycle, produce more plastic products per unit time, meet the market’s large demand for plastic products, especially in the case of large-scale production, it can better reflect its advantage of improving production efficiency.
Improve the quality of plastic products
On the one hand, as mentioned earlier, by preheating the mold and plastic materials, the filling effect and molding accuracy of the plastic in the mold can be improved, thereby reducing molding defects and improving the quality of plastic products. On the other hand, during the molding process, the heat continuously emitted by the heating lamp can keep the temperature of the mold and plastic materials stable, avoiding deformation, warping and other quality problems of plastic products caused by temperature fluctuations.
For example, in the production of some plastic products with high requirements for shape and size accuracy, such as plastic housings, precision plastic gears, etc., the use of this heating lamp can ensure stable product quality and meet high standards of quality requirements.
