Wire is all around us and it forms joints in our structures, stabilizes our tires andtransports electricity. In almost every complex product there are components made fromwire. In wire drawing hot rolled material is drawn through a single or a series of tools calleddrawing dies, reducing the cross-section and enhancing the mechanical properties of thematerial. The tribological conditions in wire drawing are quite extreme and the high frictionbetween the wire and the die which leads to plenty of heat going into the die, resulting in hightool temperatures. Previous studies have shown that by reducing the tool temperature it ispossible to increase the productivity without risking an increased tool wear, this makes thecooling of the tool of high importance for the wire drawing process.Triply periodic minimal surfaces (TPMS) which have lately been enabled to be manufacturedby the use of additive manufacturing (AM) have shown great potential to be used for coolingapplications with demand on high efficiency. In this study a tool holder for wire drawing wasdesigned utilizing TPMS and was manufactured using laser powder bed fusion (LPBF). Thecooling efficiency of the manufactured tool holder was evaluated and compared to a con-ventional tool holder in an industrial wire drawing process. The study shows promisingresults on improving the cooling efficiency in the process by using the TPMS AM toolholder.
