Abstract: An automatic unit for hot molding, e.g., forging or stamping, and subsequent trimming of metal parts. A molding press and a trimming press are served by two robot pairs. One robot of one pair delivers hot ingots to the molding press, the other pair of robots moves the part being molded step-by-step through successive stampings, and the other robot of the first pair delivers the fully molded part to the trimming press. The robots of the second pair move in mirror-image relation. The ends of the robot arms of the second pair are accommodated by depressions in the molds during the various stamping operations.
