Efficient quenching will harden the sheet metal by transforming its microstructure from austenite to martensite. Studies on quenching process through numerical simulation was highly favorable in obtaining optimized parameters for manufacturing-used. This can avoid waste production during the HPF process and reduce the time consumption from real life experimental work. In this paper, the process and the details of the hot press forming process was reviewed based on previous reference journal. The parameters varied in the paper such as forming temperature and the blank holding force was explained in term of its effect on the process. The effect of cooling channel design parameter in the hot press forming die such as the cooling duct diameter, the shape and the surface distance were also discussed and overviewed. Lastly, the research has concluded the more biggest size diameter with circular shape and nearest to the location of cooling channel was proposed to the best cooling rate and the most economical.</p>}, number={5}, journal={CFD Letters}, author={Ng, Chuan Huat and Md Yahaya, Shamy Nazrein and Fung Lai, Chee and Lun Chung, Yao and Ehsan, Ariff Asyraf and Baehr, Ruediger and Grote, Karl Heinrich}, year={2021}, month={Jan.}, pages={1–12} }
