    摘要: The invention relates to a molded piston, in particular an injection-molded piston (1) of fiber-reinforced plastic, which is seated slidably in a receiving bore (2) of a housing (4) and is embodied as a cup-shaped body with a piston bottom (6) and a sleevelike piston wall (8) protruding away from the bottom, and the face (10) of the piston bottom (6) pointing away from the piston wall (8)is pressure-loadable, and there is at least one injection point (46) oriented with a molding channel of a molding tool. The invention proposes that the injection point (46) is disposed on the other face (22) of the piston bottom (6), that is, the face pointing away from the pressure-loadable face (10), and the piston bottom (6), because of one or more recesses (48) present in this face (22), has a lesser wall thickness in the region of the injection point (46) than in the regions (52) adjoining it.
