3-D printed cooling channels to produce PHS parts with tailored properties
Abstract:
A hot stamping die includes a body having a stamping surface, and cooling channels within the body. The cooling channels are positioned to transfer heat from region(s) of the surface to the channels. The hot stamping die also includes a heating element within the body, separate and apart from the channels. The heating element is positioned to heat region(s) of the body different from the region(s) of the surface at a rate greater than heat transfer from the channels to the region(s) of the surface.
