Abstract: This scientific paper presents the research conducted for defining the characteristics of the conformal cooling systems used in molds for injection molding processes (IMP). By utilizing laser-sintering additive manufacturing (AM) technologies, this type of cooling systems could be used to minimize the cooling and cycle times in the IMP’s and provide a homogeneous cooling necessary to maintain a consistent quality of the part. The paper also presents an overview of the AM technologies used in manufacturing conformal cooling molds and the main guidelines for designing these cooling systems. The research shows that the efficiency of these channels is based on the channel system’s design and for plastic parts with a lower complexity the improved temperature distribution compared to conventional cooling systems could be negligent. The research is conducted by using Finite Element Analysis (FEA) and CAD modeling to compare different conformal shapes, as well as their cooling efficiency on a plastic part. The simulation studies are done to determine the temperature distribution in each case study. These trials are done to assess the productivity benefits that arise from the use of conformal cooling channels compared to conventional channels that utilize baffles and bubblers
