In Aluminum alloy high pressure die-casting, controlling the mold temperature is critical to achieving high quality products, high productivity, and long operating life of molds. The temperature is controlled by the circulation of a fluid through flow channels made in the mold by drilling cylindrical holes and sealing excess parts. These straight flow channels do not function enough to cool the mold and they shorten the mold life, and on top of it, drill processing costs high and takes time. Our goal is to create free-formed flow channels which can efficiently cool the mold. We plan to make multiple parts of a mold to which we create flow channels freely by machining, and join the parts by solid-state joining. In this study, SKD61 steel plates were joined by SPS (Spark Plasma Sintering) method, and the mechanical properties of the joints were examined.
