High Technology for Blown Film
A global supplier of complete systems for both mono- and multi-layer blown film, Addex has been an innovator in developing technologies that help leading-edge processors make better products, including a number of industry firsts, among them a gauge-controlling system that relies on adjusting the IBC flow to correct thickness variations. Addex has also developed unique approaches in die design with the novel REDI (for regular division) die, haul-offs (the unique Gauge Band Randomizer), and most recently winding, with the SuperWind. “Our customer base is primarily those film processors who use leading-edge technology as a means to differentiate themselves from their competitor and in the process improve their own bottom line,” remarks Rick von Kraus, Addex president. “Leading-edge technology is what Addex is and always will be about.” Addex maintains a complete demonstration line in Stoughton, just southwest of Boston, on which it can demonstrate its entire technology range.
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.
