A mold cavity is formed by movable dies actuated by an operating linkage. A casting metal is pumped into the mold by a pump injection assembly to form composite articles, such as wheel weights having a clip for rim attachment and the casting. A pivotable transfer mechanism has two angularly disposed pick-ups which operate in unison to first simultaneously pick-up a clip from a clip supply magazine and pick-up the molded composite article from the mold. The transfer mechanism is then pivoted through an arc to relocate the pick-up such that when the pick-ups again operate in unison, this time they introduce a new clip into the mold and simultaneously therewith pass the composite casting to a cut-off position at which the sprue is removed. The composite casting is then removed from the pick-up and passed down a chute to a storage bin. The transfer mechanism operation and the molding operation is controlled by logic which senses a prior condition to determine the completion of each prior operation before proceeding to the next step of the process without regard to the time element.
