Abstract: The post-mixer for split casting moulds (1, 2) for the processing by shaping of multi-component plastics has a channel system disposed in the parting plane and exhibiting mould throttle points. The channel system consists essentially of a main feed channel (4), which after a first throttle point (5) is branched into at least two side channels (6) and (7). For a smooth entry of the plastics component composition into the mould cavity of the casting mould as well as for a uniformly good mixing intensity throughout the entire injection cycle, the side channels have several throttle points (9, 10, 11) and (12, 13, 14), a change of direction of the side channels taking place between each two throttle points. The side channels open into a further chamber (19) connecting with a feed channel (20) leading to the mould cavity (21).
