An EAP generator is described, including at least one EAP stack that is disposed between two force-transferring surfaces disposed parallel to one another, having at least one layer, facilitating relative displacement between the end of the EAP stack and the force-transferring surface facing toward that end, in particular a deformable or friction-reducing intermediate layer. A corresponding method for generating electrical energy from elongation energy on a capacitive basis by charge displacement is also described.

A method for regulating an injection molding process in which process setting variables of an injection molding machine are controlled via a regulating module, which receives data from a process-internal sensor system of the injection molding machine, data on the fabricating sequence of the injection molding component parts from an external sensor system and/or data on the quality of a fabricated injection molded component part from an online component part control, evaluates these data in a quality prognosis module and, as a function of the data evaluation, performs a change in the process setting variables of the injection molding machine, because of the change in the process setting values, the working point of the injection molding machine being changed so that the quality features of the injection molded component parts fabricated using the changed working point lie within the specified tolerances of the quality of the injection molded component parts.
