A retrieval system for rapidly removing articles from a plastic molding machine or other manufacturing process includes two pairs of lightweight non-metallic telescoping retrieval tubes arranged for telescoping motion into and out of an open mold. Each pair of telescoping retrieval tubes is coupled to a pair of slidable bearing tubes. A movable one of each pair of retrieval and bearing tubes is driven in concert by a low inertia cable or other drive system. A fixed one of each of each pair of retrieval and bearing tubes includes longitudinal strips of plastic bearing material.
