Injection molding is one of the most important manufacturing processes in plastics processing for the production of mass-produced articles and technical parts for the automotive, electrical and medical industries. The injection velocity during the injection phase is a particularly important machine value, which has a decisive influence on the internal and external properties of the part. As state of the art, the machine operator adjusts the injection profile iteratively which is costs and time consuming. This process is based on recommendations from the material manufacturer and personal longtime experience. A uniform strategy does not exist. Due to this challenge, various injection strategies have been investigated by performing injection molding simulations in order to simplify and improve the setup-process automatically. The aim is to develop a generally valid injection strategy. As the next step, the developed injection profiles have to be be validated in practical injection molding trials.


Your task focuses on practical work. You will validate and adapt different injection strategies for three different parts. Your daily work will be the planning, execution and evaluation of injection molding trials. We will discuss the results regularely to enhance your injection molding process knowledge.
