Plastics and rubber technologists specializing in molded parts plan the production of molded parts based on order data or specific customer requirements. To do this, they select suitable processing methods such as injection molding, blow molding, foaming and thermoforming as well as raw materials, additives and auxiliary materials. They determine processing parameters such as temperature, time and pressure, set up the production machines accordingly and monitor the entire production process. When processing or finishing the molded parts, they use non-cutting or cutting processes, temper and condition molded parts and treat surfaces. They also package, transport and store molded parts professionally.
