One of the most important elements of a die casting tool is the cooling and heating system. It provides us with the optimal operating temperature throughout the entire casting process and the appropriate quality of the castings. Constant tempering of die casting tools, on the other hand, results in high power consumption, which leaves a large environmental footprint and increases unnecessary process costs. These consequences are inevitable, but companies try to minimize them in various ways. The thesis presents a test of a new tempering device on a die casting tool. We compared it with the existing tempered system. The test itself took place in three parts. In the first part, we tried to approach the temperatures in the tool that we had with our previous system. In the second part, we reduced the solidification time of the alloy in the tool and set a reference curve by which the tempering machine adjusts the cooling or heating of the tool according to needs. With the final optimization, we determined the capabilities of the tempering system and achieved a 16% reduction in individual cycle time, higher productivity and lower energy costs.
