Engineering updates including quick screw exchange technology

摘要

Davis-Standard LLC is introducing a slew of engineering updates to its extruders, such as a new extruder frame, innovative feedscrew design, and quick screw exchange (QSE) technology. The standardized extruder frame is built with additional space to simplify maintenance and improve heater access. Computer designed stainless steel feedscrews provide reliable melt homogeneity for resins like acid copolymers, which improves bond performance to materials such as aluminum foil. Other extruder advantages include electrical barrel heating with air-cooled blowers for each zone; temperature controlled water cooling for gearbox oil cooler, water-cooled screw, and feed section; and fixed die support and thermal expansion capability.
