Performance of die cooling system design in hot stamping process

Influence of Conformal Cooling Channel Parameters on Hot Stamping Tool and Press-Hardening Process

“…Furthermore, thermal expansion proved to be the main reason for deformation of the hot forming tools, which causes the distortion of the cooling channels, and the stress concentration at corner of the cooling channels. Recently, Hung et al [10] stated that the blank thickness, the distance from the tool surface to the cooling channel edge, and distance between cooling channel edges are the parameters that have marked effects on cooling performance. These studies mentioned so far are mainly focused on straight drilled channels, however to improve cooling efficiency, conformal cooling channels (CCC) are increasingly adopting thanks to opportunities offered by additive manufacturing (AM) technologies in combination with the development of powders with high thermal conductivity.…”

Design of a transfer system for the automotive industry

“…The part complexity is quite high, so knowledge and research in this field has been increasing. [8][9][10][11] Gomes et al 12 developed a study to reduce the number of iterations necessary in the design of a stamping tool, in order to control the elastic return of the material. As a result, very positive results were obtained to be applied in the current process, with a cost reduction of 71% and 68% reduction in the time required for the study of elastic return.…”

Effect of CeO2 on high-temperature wear resistance of WC/Fe-based coatings

“…Hot stamping is a process that uses the principle of metal thermoplastic forming to heat the material to the recrystallization temperature for processing, and then rapidly cooled and quenched to form a mechanical part [1][2][3]. The formed parts have the advantages of high bending strength, lightweight and high complexity, and are widely applied in the automotive field.…”
