Davis-Standard: Flex-Master Provides Affordable Efficiency for Short Runs
Davis-Standard’s newly introduced Flex-Master 1300 extrusion coating machine is a cost-effective option for smaller production capacities. Engineered for short runs of one to two hours for common flexible packaging structures, the Flex-Master combines several widely-used Davis-Standard machine components into one integrated package. The machine’s versatility enables processors to extrude LDPE, LLDPE, m-LLDPE, Surlyn and EVA. Coating speeds up to 300 meters per minute are attainable in 1000mm finished roll diameters.
Modular components include an extrusion station, anchor coater, turret unwind and rewind, sandwich unwind and laminator. The 65mm and 75mm coextrusion station on display at CMM utilizes a feedblock and 1500mm die with internal deckles for edge bead savings. Both extruders are of the MAC (metric air-cooled) design with a single air cooling blower. Advantages of the carriage include motorized traversing movement and manual height adjustment. The coater includes a two-roll direct gravure, enclosed pan-fed system, arch dryer and exit pull roll station. The turret unwind and rewind feature regenerative spindle motors and drives, as well as dancer tension control and shafted operation. The three-roll laminator is equipped with a linear nip arrangement, 450mm to 760mm (18- to 30-inch) chill roll, 200mm (8-inch) water-cooled back-up roll, 165mm (6 1/2-inch) water-cooled nip roll, and closed loop water circulation system. These modular components can be combined to create monolayer, coextrusion and tandem coating machines.
The Flex-Master has already generated a great deal of interest with converters that need increased versatility. For more information, contact Ken Piora at kpiora@davis-standard.com.
