Ultra This American Kuhne line of Graham Engineering extruders comes in many configurations and 15 sizes, with screw diameters of 0.75 inch to 8 inches. The machines are extremely versatile and are suitable for use in blown and cast film, compounding, and pipe, profile and tubing extrusion. They include heavy-duty double-reduction gearboxes, deep-finned cast-barrel heaters, single- or dual-bolt heated clamps and die-hinge support arms.
What's new? Adoption of Navigator controls with all the Ultras. Also, the small and medium-sized Ultras sport newly designed barrel covers and thermocouples and an automotive-style wiring harness with quick-change plugs.
Benefits Quick and easy access to barrel heaters.
