Davis-Standard: Introduction of Cost-Effective Cast Film Line – “Cast Iron”
The “Cast Iron” film line has been developed by Davis-Standard to provide processors with a versatile and economical flat cast or embossed film processing alternative. The system is designed for producing 1.6-meter finished rolls at processing rates of 250 to 300 kilograms (550 to 660 pounds) per hour in monolayer or coextrusion configurations. Applications include cast film for CPP and stretch wrap as well as embossed film for diaper backsheets and hygiene products. System options include coextrusion using up to three extruders, discrete temperature or EPIC controls, manual or automatic dies, corona treatment, as well as gravimetric blending and rate control.
The extrusion complex is available in a 4-inch (100mm) or 3 1/2-inch (90mm) and 2 1/2-inch (65mm) standard configuration. Extruder options include the MAC (metric air-cooled) or Mark V® extruder in a floor mounted or “high boy” arrangement. All drives and power panels are pre-wired with the power panel from the primary extruder serving as the operator console. The pre-wiring significantly reduces installation and start-up time. A variety of feedblock and die combinations are also available. Davis-Standard’s full range of winders, including the PAC 50 surface winder, Horizon turret winder and TEC-2 center winder, can be added to the system based on customer specifications.
The system is capable of a maximum line speed of 600 feet per minute (185 meters per minute) for both cast and embossed film applications. Specific to cast film applications, standard equipment includes a dual-chamber vacuum box with optional air knife or air chamber and electrostatic edge pinners. Also included is a thickness gauge mounted on the casting unit. For embossed film, the system utilizes one water-cooled back-up roll for producing a “matte/matte” embossed film. The water circulation loop is pre-mounted and pre-piped, also facilitating a timely installation.
