LMG (De Pere, Wis.) has introduced its largest-ever shuttle press. The 900-ton system has a mold die capacity of 126 by 116 inches (3,200 by 2,946 mm). The total length of the press and shuttle system is 39 ft/11.9m. The platen movement is facilitated by eight main rams and two jack cylinders. Accurate platen parallelism is achieved with 45° adjustable gib guides on four of its rectangular tie rods. The press was built to mold heavy parts as large as 56 ft²/5.2m². Its shuttle system is designed to move the lower mold half to the outboard station for material loading and to shuttle the just-molded part to the opposite side for unloading. The press has a mold load feature on the shuttle table that incorporates pins that come up through the table to support the mold above the table as it is loaded via forklift truck. After the forklift truck moves away, the pins lower the mold into proper position. The press is controlled with an Allen Bradley PLC.
