The car body industry continues to manufacture body parts using lightweight nonferrous metals such as aluminum, magnesium, and carbon fiber reinforced plastic (CFRP) for light weight; however, the cost of each material is high. In addition, lightweight non-ferrous metal materials are considered to contribute to environmental problems due to higher CO₂ emissions compared to steel materials when manufacturing automobiles. Accordingly, vehicle weight reduction using advanced high strength steel (AHSS) that can simultaneously overcome economic and environmental issues is attracting attention. In general, hot press forming that uses electricity and gas as a heat source is used in the molding process of AHSS, and heating is performed through convective heat transfer. However, convective heat transfer is less efficient and consumes considerable time and energy in the hot press forming process. In this paper, we improve energy efficiency by using infrared ray heating in commercial processes with low efficiency, and optimize the process through simulation analysis.
