THERMALLY EFFICIENT MOLD APPARATUS AND METHOD

摘要

A mold insert or tool (1) of this invention is constructed having an active surface (5) formed on a thin shell (2) from a hardened tool material, thermal management passages (8) molded into the back of the active surface element (2) in an arrangement which substantially conforms to the thermal stress lines generated by the shape of the active surface (5), a copper thermal management layer (4, 9) to enclose the thermal management passages (8), and to add structure to the mold insert (1).
