Method & Evidence

AimTo investigate and quantify the improvement in cooling performance of a newly developed slice die compared to a conventional die in the hot press forming process.
MethodNumerical simulation and experimental validation
ProcedureThe cooling performance of a conventional die and a newly designed slice die was simulated using numerical methods. The slice die was then prototyped, and a hot press forming process was conducted.
