CHICAGO — Zed Industries Inc. (Booth N5534) introduced what it claims is the world's fastest pressure forming machine at NPE 1997 in Chicago. The Cam-Form Series is a high-speed, in-line pressure former with punch press-type trimming that runs at speeds as fast as 60 cycles per minute. The machine can use roll-fed material as thick as 60 millimeters.
The Cam-Form on display at Zed's booth has a 14-inch-by-14-inch mold area, but the machine is available in sizes as large as 16 inches by 26 inches. The former makes cup lids, bowls, trays plates, packaging and other small parts.
``It is intended to run in the multiple millions of cycles,'' said Peter Zelnick, vice president. ``The changeover is longer, up to two hours. But it's designed for extended runs.''
The servo-driven machine molds all types of materials, such as PET, PVC, oriented polystyrene and foam. At the show, the machine is thermoforming 12-millimeter vinyl blister packs.
A smaller version is being used in Canada for PET egg cartons, and another in France is making PVC egg cartons. Parts can be indexed, registered, counted and stacked for easier packaging.
One servo motor runs the whole machine from ceramic heaters, top and bottom moving platens, through the cooling station and the punching station. Scrap web is rewound or fed to a grinder.
The machine controller remembers the last hour of operation. If there's a problem, while a warning is issued, the controller will continue to operate the machine just as it had before the problem.
The Vandalia, Ohio-based equipment maker also manufactures skin and blister packaging equipment, heat sealers, form, fill and seal systems, die cutters, clam shell sealers and heavy-gauge thermoformers.
Zed also introduced the SC Series of in-line pressure forming equipment with an upgraded computer-control package. It features a 15-zone heating system, a secondary hanger hole punch, 110-ton trim press and a parts stack with an automatic counter/unloader in a 22-by-22-inch mold format.
The SF Series features servo-driven platens and pin chain film indexer and a color touch-screen computer control with complete job memory capabilities.
