High Technology for Blown Film
High Technology for Blown Film
Addex Inc., based in Stoughton, Mass., USA, was founded in July 1989 as a supplier of high-performance components for blown film production. Today, Addex supplies some of the most sophisticated technologies capable of producing films with the lowest possible gauge variation, without camber and the highest possible output. The company is a leading manufacturer of many patented blown film components and systems including manual and automated gauge controls, internal bubble cooling systems, air rings, oscillating haul-offs and dies, as well as leading designs of gravimetric blenders and bubble cages. Addex’s focus on research and development has resulted in over 14 U.S. patents. These patents cover Automatic and Manual Film Thickness Controls , an All Digital IBC Control that reduces scrap, a Coex Die design that assures even thickness profiles for inside layers, and a Horizontal Reversing Nip that doesn't cause camber (zig-zagging of the film). Addex works continually to develop unique products that help processors increase yield and realize major raw material savings. For example, Automatic and Manual Film Thickness Controls reduce film thickness variations up to 70% and All Digital IBC Controls reduce changeover times up to 75% thus considerably reducing scrap rates. In addition, a special Coex Die design reduces the thickness variations of the inside layers by up to 30% and Continuous Gravimetric Blenders save 1-2.5% of raw material compared to everyday gravimetric batch blenders. Addex products can be retrofitted to any new or existing blown film line in order to maximize film quality and achieve maximum output. As a global leader in blown film extrusion technology, the company supplies customers in the U.S., Europe, the Middle East, and the Far East. The company is represented in regional markets by independent sales representatives. For more information, visit www.addexinc.com.
Offers performance improving components for blown film extrusion lines of all makes: automatic gauge controls, manual gauge control air rings, digital IBC systems, oscillating hauloffs, continuous gravimetric blenders, film flattening annealer, special mono- and multilayer dies, bubble cages and others.
Patented Automatic Gauge Control systems reduce gauge variation by a minimum of 50% because of the multitude of its control zones. Patented Compact Gauge Band Randomizer (GBR) oscillating hauloff does not induce camber (zigzagging) of the film. REDI (regular division) die technology yields 20-25% lower film thickness variation of the inner layers in coextrusion.
All components contribute to the reduction of plastic resins i.e. they help reduce the plastic footprint !
Extrusion processors no longer need to chose among speed, quality, and flexibility, based on exhibits at K 2013.
Across all extrusion technologies, expect to see new standards in speed, quality, flexibility, and efficiency in both energy and material usage.
Unit is said to boost output by 15% to 30% and reduce film thickness variations by up to 70%.
Blown film towers may have been scarce, but there was no shortage of new technology aimed at helping to make extrusion processors more profitable.
There won't be many blown-film lines running, but there is still much in the way of innovation going on in extrusion and compounding.
New Digital Internal Bubble Cooling (DIBC) system from Addex Inc., Stoughton, Mass., is said to deliver the fastest reaction time in the industry to ensure precise bubble control, helping processors to speed product changeovers and significantly reduce scrap.
In blown film, equipment and material suppliers have come together to push five-layer technology into non-barrier applications previously held by three-layer films.
In most segments of extrusion technology, the word at K 2010 is more.
This NPE show won’t have a lot of extruders on the floor, either running or static. Instead, look for videos and announcements of new technology. You will also find lots of ingenious peripheral devices to improve output and quality and save resin. Some will do all three, and cost less into the bargain.
Injection MoldingHybrid Press Has Electric ClampNew injection presses that combine servo-electric and hydraulic movements to achieve high performance with energy efficiency will be discussed by Arburg Inc., Newington, Conn.
Addex Inc., Stoughton, Mass., claims it now can produce nearly perfect blown film rolls with an oscillating die—an industry first.
Four non-contact, ultrasonic sensors-two below the frost line and two above it-are part of a new, patented "early warning" IBC control from Addex Inc., Stoughton, Mass.
Several extruder OEMs offer the four-motor, high-torque CMG drive from K&A Knoedler GmbH in Germany-but only on a single small extruder size, typically 90 mm.
NPE 2006 presented a bevy of features to make film, sheet, pipe, and profile extrusion more efficient.
A new blown film winder from Addex Inc., Stoughton, Mass., uses a cutover with a serrated knife that comes up out of a long slot in the lay-on drum and shoots sideways, making a clean cut.
The new factor in extrusion machinery at this NPE is the influx of Asian suppliers.
The second extruder built in North America with a gearless permanent-magnet torque motor is a new coextruder from Addex Inc., Stoughton, Mass. (The first machine of this type was built a few months ago by Davis-Standard.
Economical, non-nuclear capacitance gauges are opening new markets in blown film—primarily in barrier films, where they previously suffered serious shortcomings. New gauge designs, and new ways of mounting them, make capacitance technology much more flexible.
Machine-direction orientation is still discovering new market opportunities. But the technical difficulties are so great that some big projects never came of age. New equipment could make it easier.
At K 2004, at least a half-dozen European machine builders will show new direct-drive extruders running gearless—or nearly gearless—drives with substantially higher rpm and output rates than conventional extruders of the same size.
