Davis-Standard to Showcase Versatile Product Line at K 2007

During K 2007 Davis-Standard will display extrusion equipment engineered to meet the economic and production demands of today’s plastics marketplace. Equipment to be shown in hall 16, stand A43 will include the Euro Blue™ II extruder, HPE extruder, and a system for manufacturing cotton swab sticks. A Davis-Standard cold feed rubber extruder mounted on a Uth roll-ex® 70 gear extruder common base/assembly will be shown at the Uth GmbH booth in hall 15, stand A50. Product samples and videos of other technology including sheet and foam capabilities will also be displayed. Company representatives and information about Davis-Standard’s Converting Systems and Extrusion Systems business groups in Europe will be available throughout the show. The following is a summary of exhibit highlights.

Euro Blue™ II Extruder, 75mm – This extruder is an upgraded version of the original Euro Blue™ introduced in 2004. It provides high quality specifications and processing rates at a reasonable cost. In stock machines can be delivered in as quickly as one week based on location. The Euro Blue II includes a double reduction gearbox with helical carburized gears, an integral high capacity thrust bearing, cast iron feed section, four-zone DS1000 bi-metallic barrel assembly with heated clamp arrangement, and DSBM-T high performance barrier mixing feedscrew, among other high performance features. It also comes with a two-year warranty and support from D-S Brookes’ UK-based technical and aftermarket services. Like its predecessor, this model is engineered for custom profile and tubing applications, as well as basic wire and cable processes. The extruder range currently includes sizes of 50mm, 60mm, 75mm, and 90mm in 24:1 configurations.

HPE-100A Extruder – This 25mm extruder exemplifies processor demands with a small footprint, performance features, and a fast delivery for coextrusion and multi-layer applications. Available in sizes ranging from 19mm to 44mm, the HPE utilizes a direct drive motor rather than belts and sheaves, and has a small footprint for close proximity to the common die. It swivels on a column to permit positioning at any angle and vertical adjustment is accomplished by means of a lift screw. All sliding/swiveling components can be locked firmly into place for rigid positioning. The HPE is also available in a horizontal configuration.

Cotton Swab Stick Line – A line with an all-in-one Betopac machine for pulling, cutting and packing small serrated tubes will manufacture cotton swab sticks during the show. The Betopac is capable of packaging up to 4,500 sticks per minute, but will package around 2,000 to 2,500 sticks per minute at the show. This machine simplifies the downstream process by automatically placing sticks into a tray or box and staging them for a secondary process. The sticks at the show will have a 2.5mm nominal OD, 1.9mm ID and length of 72mm with an OD tolerance of +/- .05mm, and cut length tolerance of +/- .5mm. Davis-Standard will run polypropylene with an MFI of between 3.0 and 3.5. The line will be powered by a 60mm Euro Blue II extruder.

Cold Feed Rubber Extruder/Uth roll-ex® 70 – Davis-Standard and Uth have combined technologies to exhibit a 90mm cold feed rubber extruder as an option to use as a screw feeder when connected to a roll-ex 70 gear extruder. This arrangement, shown for the first time, enables precision extrusion of cold feed rubber preforms for post processing of compression molding. This precision extrusion complex will showcase the extrusion process knowledge of Davis-Standard with the gear pump and straining expertise of Uth. The cold feed extruder features a high performance low-shear feedscrew, and has a smooth barrel design for cost-effective maintenance of both the feedscrew and barrel. The roll-ex gear extruder is modular in design and offers advantages such as a minimal material dwell time, low temperature increase and a hydraulic system that gives operators access to all major components.

Sheet Capabilities – A video showing Davis-Standard’s sheet capabilities including foam, flexible and rigid sheet extrusion, and single and multi-layer coextrusion applications will be broadcast during the show. In recent years, Davis-Standard has experienced significant growth in this area specific to processing PET and polystyrene (PS) foam. PET capabilities include technology to process multiple materials including recyclable PET in flake form and low bulk density PET ranging from 100 percent post consumer waste to virgin APET. This includes configurations for running mono-layer, ABA coextrusion and side-by-side sheet using virgin PET, regrind PET and PP resins. In the area of PS foam, Davis-Standard supplies systems for both thermoformed and flexible packaging applications. These systems are equipped with tandem single screw extruders with gas injection, or with twin screw extruders with gas injection. PE and PP foam systems for packaging applications are also available. Davis-Standard also supplies standard and custom roll stands, winders, in-line control systems, feedscrews, sheet dies, melt pumps, thickness measurement systems and other auxiliary equipment.

This upgraded version of the original Euro Blue™ provides high quality specifications and processing rates at a reasonable cost.
