A tool for hot stamping metal sheets, formed least partially of a base block and a functional layer, is proposed. The functional layer comprises cooling channels and multiple functional layers, which building upon each other create the connection to the base block. The cooling channels are designed as a cooling channel array and are produced in a laser sintering method.

Tool for hot stamping and method for making the tool

A hot forming die that includes a first die and a second die. The first die has a first die structure that is formed of a tool steel. The first die structure has a first die surface and a plurality of first cooling apertures. The first die surface has a complex shape. The first cooling apertures are spaced apart from the die surface by a first predetermined distance. The second die has a second die surface. The first and second die surfaces cooperate to form a die cavity. Related methods for forming a hot forming die and for hot forming a workpiece are also provided.
