Abstract
Plastic injected parts have become the most common type of component in industrial products. The main challenges faced by the industry in the use of injection molding in terms of productivity are related to mold manufacturing time and injection cycle time. Steel has traditionally been used to make molds. To overcome this problem, molds made of aluminum alloys, which have four times the thermal conductivity of steel, can be used. On the other hand, there are significant technological challenges in using aluminum molds for injection of plastic parts, including issues with mold design, injection process simulation, mold manufacturing, and try-out. At the same time, the use of an aluminum mold necessitates an economic analysis because, while the mold material is more expensive than steel, the injection process gains productivity. In other words, deciding between steel and aluminum molds involves both technical and economic considerations. Decision making related to uncertainty assessment and management is becoming increasingly important in various scientific fields. The presence of uncertainty, the evaluation of alternative scenarios, the existence of quantitative variables as well as subjective information, the interdependence of variables, different dimensions, and the presence of non-deterministic variables all play a role in the selection of the type of material used in polymer injection molds. The goal of this paper is to present a decision support model for deciding whether to use steel or aluminum in the development of polymer injection molds. This model will be used in the DEMALAP project, which is part of the Rota 2030 Program, to demonstrate the feasibility of using aluminum alloys as a base material for the manufacture of high-productivity injection molds, with the goal of increasing global competitiveness throughout the life cycle of the injected thermoplastic part.
