Here are some common applications for Goldisgood’s 321mm, 220v, 800w transparent halogen infrared heat lamp heating element for plastic molding:
Applications before plastic molding
Plastic raw material preheating:
This infrared heat lamp can be used to preheat plastic raw materials before feeding them into the injection molding machine or other plastic molding equipment. The infrared heat emitted by it can evenly penetrate the plastic raw materials, raising the overall temperature of the raw materials. The preheated plastic raw materials have better fluidity, can fill the mold cavity more smoothly during the molding process, reduce problems such as incomplete molding and lack of material caused by low raw material temperature, and help improve the quality and integrity of the molded products.
Different types of plastic raw materials have different requirements for preheating temperature. By adjusting the distance between the heating lamp and the raw material, heating time and other parameters, the preheating temperature of the plastic raw materials can be accurately controlled to meet the needs of various plastic molding processes.
Applications in the plastic molding process
Mold heating assistance:
During the plastic molding process, the temperature of the mold has an important impact on the quality of the molded product. This infrared heat lamp can be used as an auxiliary means of mold heating to heat the mold surface or specific parts. By maintaining the mold in a suitable temperature range, such as during injection molding, the cooling speed of the plastic in the mold can be reasonably controlled to avoid quality problems such as internal stress and deformation caused by excessively low mold temperature, or excessively high mold temperature, which causes the plastic to cool too quickly and affect production efficiency.
For some molds with complex shapes or products with high molding precision requirements, it is particularly important to accurately control the mold temperature. The heating lamp can be used to perform local heating or temperature fine-tuning on key parts of the mold to ensure uniform temperature in all parts of the mold and improve the dimensional accuracy and surface quality of the molded product.
Application after plastic molding
Product post-processing heating:
After the plastic molded product is demolded, some post-processing operations such as surface treatment and assembly are sometimes required. The infrared heat lamp can be used to heat the molded product again. For example, before surface painting, heating the product can make the surface smoother and more flat, which is conducive to uniform adhesion of the paint. Or when assembling the product, heat the parts that need to be hot-pressed to make the parts fit better and improve the quality and firmness of the assembly.
Applications to improve production efficiency and quality
Shorten the molding cycle:
Since it can provide heat quickly and effectively, whether it is preheating plastic raw materials or assisting in mold heating, it can reduce the waiting time caused by temperature factors. For example, it may take a long time to wait for the plastic raw materials to heat up naturally. Now with the help of this heating lamp, the required temperature can be quickly reached, which speeds up the overall production rhythm of plastic molding, thereby shortening the molding cycle of a single product and increasing the output per unit time.
Improve product quality:
The uniform heating effect plays an important role in all stages of plastic molding. In the raw material preheating stage, it ensures the good fluidity of the raw materials; in the mold heating stage, it ensures the uniformity of the mold temperature, reduces the internal stress, deformation and other problems of the product; in the product post-processing stage, it is conducive to improving the quality of surface treatment and assembly. In summary, this infrared heat lamp helps to improve the overall quality of plastic molded products, reduce the scrap rate, and enhance the competitiveness of products in the market.
