In the following master's thesis, we discussed cooling of the mould for injection molding of a part made from polyphenylene sulfide. We compared simple cooling channels design with straight drilled holes at an uneven distance from the mould core and conformal cooling design, where the cooling channels follow the shape of the mould core at the almost uniform distance. The effectiveness of both cooling methods was compared by measuring the core temperature at the end of injection cycle. Mould cooling was also considered from a theoretical point of view by calculating the heat balance of the mould and simulating the cooling of the cross section of molded part's wall at the different mould temperatures. Using differential dynamic calorimetry, we determined the degree of crystallization of samples produced under different cooling conditions based on the melting enthalpies of the crystal structures.
