Discussion on Far Infrared: Annealing Treatment of Plastic Products

An explanation of the effects of far-infrared heating through the annealing treatment of plastic products.

AMK Co., Ltd. is a company that handles industrial far-infrared heaters, heating devices, and drying equipment. Plastic molded products such as toner cases, PC parts, and headlamp housings are produced by pouring heated resin into molds and removing them after cooling to a certain extent. During this process, temperature differences occur in the plastic due to the position inside the mold, leading to distortion. This causes various physical property declines, such as dimensional changes, crystallization, and deterioration of weather resistance. Reheating to eliminate distortion is referred to as annealing treatment. This process requires precise temperature distribution and accurate temperature control, making it a field where far-infrared heating excels. Traditionally, processing was done over time in fixed furnaces with hot air, but with far-infrared heating, physical property changes can be eliminated in a short time. *For more details, please refer to the PDF document or feel free to contact us.*
