CHICAGO (July 15, 11:20 a.m. EDT) — Modularity, economical shipping and a small footprint are key features of the Macchi Coex Flex 3 blown film system.
Macchi SpA ran the three-layer film system at NPE 2003 and was to ship the show system to Transco Plastic Industries of Montreal, said General Manager Alessandro Macchi in an interview at NPE in Chicago. It will be the third Macchi film line operated by Transco.
Macchi said the Coex Flex 3 easily replaces a monofilm system because it takes up about the same amount of plant space. Modular construction allows the system to be shipped in its own container, which converts to the system´s main electrical housing during installation, he added. It can be installed in four or five days, about half the time most competing lines take, he said.
The NPE system was running three-layer film at 65 pounds per hour through a 10-inch die. Thickness deviation for the 1-mil film was only 1.9 percent on a 2 Sigma basis.
Standard components include bimetallic barrels, infrared barrel heating for energy savings and quick cooling response times. Other standard parts are Coex Flex dies with low operating pressure to allow flexibility in choosing materials, filtered and insulated air-ring and internal bubble control blowers to reduce noise and dust, nonmarking bubble guides and control-panel conditioning systems to maintain proper temperatures in demanding plant environments. Each film roll is bar coded to correlate with its production conditions.
Macchi said the Coex Flex 3 system has become the company´s most popular system, although it also supplies five- and seven-layer lines and recently entered cast-film systems. The firm builds about 80 extrusion lines a year in Venegon, Italy, and exports most of them. It soon will have capacity to build and test more lines, Macchi noted. It is doubling the size of its test area, now capable of testing eight lines at once, for next spring. It will increase production capacity by 20 percent this year by adding metalworking machinery.
Macchi is boosting its profile in North America by recently opening an office in Guelph, Ontario. Macchi North America Corp. plans to expand the office to include technical service and parts.
