A machine for compression molding plastic articles includes a turret constructed for rotation around a vertical axis. A first array of compression molds and a second array of compression molds are mounted on the turret for movement through respective first and second mold paths as the turret rotates around the vertical turret axis. A first mold charge placement mechanism is disposed adjacent to the first path for placing mold charges into molds of the first array in sequence as the turret rotates. A second mold charge placement mechanism is disposed adjacent to the second path for placing mold charges into molds of the second array in sequence as the turret rotates and independently of the first mechanism. The first and second mold paths may be spaced from each other radially of the turret axis and/or longitudinally of the turret axis.
