Abstract
A process for producing a molded part from a highly filled thermosetting starting material including: introducing the starting material into a prepressing tool; producing a preform from the starting material, the starting material being brought to a prepressing temperature by the prepressing tool and being compressed with a prepressing force to form the preform; removing the preform from the prepressing tool and introducing the preform into a finish pressing tool; and producing a finished part from the preform, the preform being brought to a finish pressing temperature by the finish pressing tool and being compressed with a finish pressing force to form the finished part. Here, the prepressing temperature is lower than the finish pressing temperature and the finish pressing temperature is at least as high as an onset temperature of a curing reaction of the starting material.
