A 3,300-ton, twin-platen injection molding press is giving Mack Molding Inc. an opportunity to work on bigger parts than it has in the past.
Mack's Southern Division recently added the machine, along with two 1,100-ton presses, as the latest step in its $9 million plan started four years ago to focus on bigger parts. All the presses are twin-platen Van Dorn Demag Caliber models equipped with parts-removal robots.
Mack added 25,000 square feet of space at its Inman, S.C., plant to accommodate some of the machines. Others are going to the division's Statesville, N.C., plant.
``The addition was put up a couple years ago to house four large-tonnage machines, so now three of them are in place and we have the potential to add another up to 4,000 tons,'' said Ray Burns, president of the division.
Burns said the firm may add a 4,000-ton machine, depending on market conditions.
The addition - which can be doubled in size if needed - houses presses of 2,500, 3,000 and 3,300 tons. The largest has a 540-ounce shot size and was up and running in late September producing heavy-truck parts.
The company sees trucks, large-screen televisions, recreational and utility vehicles and medical devices as opportunities to use its large machines.
Three years ago, Burns said, Mack supplied three transportation original equipment manufacturers, but that number has grown to eight.
Overall, the Inman operation covers 250,000 square feet. Mack also has added a Sterling central loading and drying system, as well as an automated distribution system.
The Statesville plant covers 105,000 square feet.
Mack now has 30 presses with 1,000 tons of clamping force or more.
Overall, the firm operates 117 presses in six sites in the East. Its headquarters is in Arlington, Vt.
