During many years, injection molding of the polymer molds has been proven as a quick way to make products for medium to high series production. In order to produce a quality product, all stages of the process must be controlled (ex. tool, material, injection molding machine, etc.). During the last two decades additive technology regarding prototype production and, more recently, regarding finished products has been developing intensively. The biggest disadvantage of additive technology is a limited choice of polymeric materials and different mechanical properties when compared to products manufactured by injection molding technology. Creating the mold for the injection molding process is time-consuming and expensive process, also unprofitable for smaller series. By making injection molds using additive technology, we accelerate the process of production of finished products. One of the disadvantages of making molds using the mentioned technology is the durability of the molds. In order to increase the durability of the mold, the area regarding application of the coating to the mold will be examined.
