The Model 50 Magnum can accommodate a 48-in. wide mold for production in-line with an extruder and a 50-in. wide mold for roll-fed applications. The Model 36 and 44 Magnum were created as a narrower options, 40-in. wide sheet and 38-in. mold width, or 46-in. wide sheet and 44-in. mold width respectively, with the same forming tonnage as the Model 50 Magnum. A product depth of 7.5 in. can be formed in material gauges of up to 0.090 in. The Progressive is a compact, versatile machine capable of forming, pre-punching, and trimming in one motion, all on a common platen. Also offers Model 50 Vertical Trim Stack (VTS) Trim Press was the first to market a high-speed vertical trim press with “Ballerina's” patented “Auto Start” servo feed, which allows hands free threading of the sheet into the treadle sheet guides. The Model 44 Thermoformer’s provides exceptional performance throughout a range of sheet types, including TFPP, PP, PET, CPET, HIPS, and polystyrene foam. The Model 30 Trim Press is another in the line of the highly successfully and patented NT style trim presses.
Exhibitors at this year’s show introduced an assortment of new machines and upgraded models with designs incorporating the latest in mechanical, hydraulic, and electronic technologies.
Most of the developments will focus on in-line systems.
There will be fewer thermoforming machines on display at NPE 2003 than at many recent NPEs.
NPE had its share of innovations in thermoforming, notably a new machine that opens the small-bottle market to thermoformers. New trim stations offer more in the way of output and versatility. And more machines are now outfitted with off-the-shelf controls to facilitate servicing. A line of formers from Australia also arrived in the U.S. (Note: additional NPE thermoforming news appeared in May and June—see Learn More box.)
For thermoforming of both heavy-gauge sheet and thin-gauge packaging, the show will present new machines with unusual flexibility, able to form a wide variety of products and materials.
Continuous in-line packaging systems will be the main emphasis in thermoforming at K 2007.
One of the fi rst commercial continuous sheet splicers has been developed for polystyrene foam thermoforming lines.
The new 4242 berry-basket tooling system from Irwin Research & Development Inc., Yakima, Wash., consolidates pre-punch and trimming operations into one station.
Several new processing technologies unveiled at NPE point to thermoforming’s growing capability to produce in-mold labeled and decorated plastic parts.
Soaring interest in in-mold finishing techniques for injection molding and fiber-reinforced composites offers new prospects for cut-sheet formers.
High-speed packaging systems dominated thermoforming news in Dusseldorf. A new shallow-draw, servo-driven system promises to make formed PP deli lids competitive with injection molded LLDPE. Other new machines use electric servo motors to speed forming of PS, PE, and PET packaging.
Perpetually in its infancy, PET foam sheet has been a hard sell for packaging producers over nearly a decade. It found successful niches in thermoformed ovenable bakery trays, meat trays, and reheatable dinner trays for home delivery to disabled persons.
