The name VAREX is known around the world as a synonym for powerful and reliable extrusion of high quality blown film. With the development and upgrading of the VAREX, German based engineering company Windm?ller & H?lscher (W&H), with headquarters in Lengerich/Westphalia, has succeeded in constantly setting new benchmarks in regard to productivity, film quality and flexibility of applications. Since entering the extrusion technology market in 1967, W&H has launched more than 2000 systems with over 5000 extruders.
At K2013, the company revealed that E-24, a secret that it has promised to divulge during the show, is VAREX II. With VAREX II, W&H presents the innovative successor to the renowned VAREX blown film system and in doing so lifts the secret of one of the most significant development projects in the company's history.
VAREX II combines the knowledge and experience gathered over many decades with continuous development and upgrading of each and every component of the line. The underlying goal was to consistently increase the productivity and flexibility as well as improve the film quality, while at the same time giving due consideration to sustainability and ergonomic design.
The VAREX II is modularly designed and can therefore be tailored to any user specific requirements and production environments as well as to the product portfolio to be handled. The modular concept also allows for later retrofitting with optional modules and new technologies to accommodate future requirements as and when the need arises. In this way the latest state of the art is guaranteed for the extrusion line at all times. The consistent integration of all components into a central line control system ensures ease of operation and monitoring from an ergonomically optimized central operating unit.
All system components are laid out to guarantee reproducible production of superb film quality at maximum output rates. Owing to the powerful flow-optimized barrier screws, W&H extruders provide maximum flexibility with the processing of the most diverse resins. The broad selection of MAXICONE dies available ensures that there will be the correct die for any product specification. The patented melt distribution system allows for an extremely compact design and keeps pressure losses low. In this way high melt throughputs and very tight film gauge tolerances are achieved. OPTIFIL P, W&H's proven gauge profile control system enables targeted control of the melt temperature on the bubble circumference, reducing film gauge tolerances to the very minimum. The result is reduced resin usage and optimum quality of the film produced. One of the many highlights of the VAREX II is the new bubble collapsing unit in the film haul-off. Thanks to the automatic adjustment of the lateral guide elements, film flatness is improved and film curvature minimized. Featuring a comprehensive range of optional specifications, the new FILMATIC S II winder can be tailored to any application and will produce perfect roll quality, even when handling highly sophisticated film products.
Effective film cooling is a requirement for maximum productivity. The new ARCTIS air ring, an upgrade of the OPTICOOL high-performance air ring presented in 2009, substantially contributes to a further incrMercurial Victory CR7 Low
