Abstract

PURPOSE:To mold a good composite body under pressure without mixing powders of dissimilar kinds with each other by providing a shutter in the gap in a guide wall which segments the inside of a supply hopper for powders of dissimilar kinds and lowering the shutter into dies in the stage of supplying the powders to the dies. CONSTITUTION:The inside of a hopper 6 for supplying powders is divided by a guide wall 9 for partitioning, and metallic powders 7, 8 of dissimilar kinds are packed in the respective chambers. When a die cavity is formed by moving the hopper 6 to the power feed position and lowering a lower punch 2, a shutter 5 provided in the gap in the wall 9 is lowered by the piston rod 10 of an air cylinder 4 to segment the inside of the die cavity. Dissimilar metals are dropped respectively into the segmented chambers to fill the die cavity. The shutter 5 is then pulled up, the hopper 6 is moved, and the powders are molded under pressure by means of the upper and lower punches 2, 3 of a press machine, whereby a composite molding 13 of the powders of dissimilar kinds is obtd.
