An announcement from Bill Hunter, CEO of Hunter Automated Machinery Corporation, the world leader in automated matchplate molding machines, mold and sand handling equipment for the foundry market, Jim Fitzgerald will assume the newly created position of Chief Operating Officer, effective Friday – February 1, 2013.
Jim began his career as a machine assembler for Hunter in 1977, shortly after his graduation from Central College in Pella, Iowa. For the past 35 years, he has been dedicated to shop operations and manufacturing management at Hunter. He was promoted to his current position as Vice President at the company, following Art Hisel’s retirement in 1992.
Jim’s responsibilities as COO will include all Schaumburg, IL-based activities, with the exception of Sales and Marketing. His goals will include maintaining and building upon the company’s reputation for producing the world’s highest-quality foundry machinery and for providing superior after-sale support.
“Jim brings the education, proven ability and determination to help Hunter achieve these goals. His leadership and commitment to our company is unquestionable and exemplary,” said Bill Hunter in making this announcement.

Custom configured solution from Hunter allows major Pennsylvania foundry to integrate mold handling line with other brands of automatic molding machines
See the video HERE.
Schaumburg, Illinois (USA) – The Buck Company is an ISO 9001: 2008 Certified foundry in Quarryville, Pennsylvania, near Lancaster and nestled in the Susquehanna Valley near the Maryland border. Here, ferrous and non-ferrous castings of ductile, gray and malleable iron, as well as aluminum and brass are poured in medium and long runs to produce a wide variety of end products for the agricultural, metalworking, materials handling, marine, military and other market segments.
A challenge was presented to Buck’s longtime molding machine supplier, Hunter Automated. Another brand of molding machine had been acquired at Buck for a particular use in the non-ferrous foundry. Hunter was asked to provide a mold handling line for the particular conditions and footprint available at Buck and to devise a “handshake” mechanism to interface with this new machine.
It was determined that the best solution for the floor space and pouring equipment logistics was a Hunter HLH linear mold handling line. However, the pouring height of the Hunter line did not match the mold discharge height of the other machine brand, so an elevation change mechanism was needed to accommodate the difference between the mold’s exit height from the machine and its placement onto the pouring line section of the Hunter line.
The solution was found in a walking beam (boardless) conveyor line devised and patented by Hunter, combined with an articulating arm and elevator mechanism that could raise the mold onto the pouring line for loading of the weight and jacket, all without risking mold shift.
As the mold exits the machine, in this case at Buck, a series of walking beams gently sequence the molds forward to the elevator station. The “traffic cop” on this conveyor is a plurality of proximity sensors, used to monitor each location along the conveyor section and coordinate with the pouring operation, so mold collision and back-up are avoided. As pattern changes are made, work breaks occur or melts are prepped, these sensors remain in operation to protect the integrity of the process.
Once the mold reaches the end of this standard boardless walking beam conveyor section, an articulating arm and elevator mechanism gently raise the mold to the standard height of the Hunter handling system. Achieving this result saved Buck considerable manpower in materials handling, plus floorspace and capital investment, while allowing this Hunter customer to maintain high productivity in this section of its non-ferrous foundry operation.
As Dean Martin, sales manager for Hunter, explains, “We had a meeting of the minds with the automatic molding machine builder and we worked out a feasible plan to solve the handshaking issues presented by this production scenario. There were really no serious setbacks or conflicts, as we had the common goal of satisfying Buck’s requirements with the optimum production results plus an on-target budget.” He further described how the machine builder and Hunter’s seamless working relationship helped develop this transitional walking beam (boardless) conveyor system.
Buck used the expertise of its projects manager Art Tout and non-ferrous foundry superintendent Steve Ward to work with the molding machine builder and Hunter to achieve the best solution. As Steve noted, “The Hunter linear line was more practical than the rotary turntable design, which we also have in another section of the foundry. With a smaller footprint and relatively low maintenance, it was a good solution.” He joked, in describing the way Hunter worked with the machine builder, “They played well in the sandbox together.”
The typical mold being handled on this line weighs 400-500 lbs. (181-227 kg), having been produced on the molding machine with a 20” x 24” plate dimension.
Buck President Matt Sullivan observed, “We were very impressed by the way everyone responded. The machine builder and Hunter actually needed very little input from us. We’d presented Hunter with some very tight floorspace restrictions and they worked hard to overcome the challenges for us. We had good experiences with the HLH lines in other parts of the foundry in the past and we were confident it would do the job here, even being modified. We knew the HLH would work from morning to night with few, if any, problems. The option of going vertical with the mold cooling was vital, given the floorspace.” He also noted the installation and the modification of the overall system was seamless.
Martin concluded by noting, “…the boardless conveyor system used here at Buck, while a special modification to our standard board conveyor design, was completely designed, engineered and built by Hunter personnel. We’ve used this solution and others at several companies since the Buck install, with very satisfactory results.”
Hunter holds several patents on the unique features of its mold handling systems, which can be utilized with any boardless molding machine.
