The master's thesis presents the development of the cooling system of the plastic injection molding tool. A comprehensive review of existing conventional and conformal design solutions and key analytical models was performed in the theoretical part of the thesis. We designed four different cooling systems. The individual solutions differ in the length of the cooling channels, the cross-section of the channels, and their position in relation to the working surface. We have performed numerical analyses for the designed solutions, where we have checked the cooling efficiency, the influence of thermo-mechanical loads, and hydraulic losses through the tempering system. In the second part of the master's thesis, the experimental evaluation of the individual solutions is presented, which we used to validate the numerical model. We found that a properly designed conformal cooling system allows for more efficient heat dissipation from the tool and ensures a uniform temperature across the surface of the tool insert.
