Abstract
In a method for producing a shaped part, a closing movement is executed by displacing at least one of two mold halves of a high-pressure resin transfer tool from an open position into a pre-closure position of the resin transfer tool such that an opening gap between the mold halves is sealed air-tight by a sealing device of the resin transfer tool to thereby enclose a cavity. The cavity is evacuated by pumping air out of the cavity, and the closing movement is continued by displacing at least one of the two mold halves from the pre-closure position into a final closure position, in which the mold halves are sealed against one another by a further sealing device to allow filling of the cavity, enclosed by the two mold halves, with resin without leakage during a high-pressure resin transfer molding process.
