SHOW PREVIEW | NPE 2018


(PIC: American Kuhne will demonstrate a medical tubing extrusion line during the show


controls are now available for American Kuhne extrusion systems such as those for medical tubing and profiles. There are three levels of functionality: XC100 for stand-alone extruders; XC200 for one or more extruders in simultaneous operation; and XC300 for integrated production lines with the extruder and components such as a puller, water bath, or winder.


At NPE2018, all three controls will be shown installed on American Kuhne extruders. Justin Kilgore, vice president of engineering at


4.0 (also called the Industrial Internet of Things, or IIoT). “The digital transformation occurring in the plastics industry will significantly influence innova- tion in machine design and productivity on the production floor,” said John Christiano, vice president of extrusion technology at Davis-Stand- ard. “With predictive maintenance technology, machine operators will be alerted to issues before they happen, preventing unnecessary downtime while also collecting valuable data.” The line, which features the company’s Thermat-

The MD-12382 grade is a kink-resistant, gamma- stable compound, one of a series of translucent Medalist TPEs offered as an alternative to silicones for applications involving the transfer of drugs, proteins, bodily fluids, or blood. � www.davis-standard.com


Graham Engineering will exhibit a range of its systems for a variety of extrusion operation, including both sheet and medical tubing. Each will be equipped with its Navigator control system, to showcase its accuracy and ease of use, says the company. “Our Navigator control technol-


ogy uses an industrial PC with a Windows platform to enable intuitive, industrial, integrated extrusion process control,” said David Schroeder, CEO of Graham Engineering. Originally developed for Graham Engineering


extrusion blow moulding systems and later adapted for Welex sheet extrusion lines, Navigator

Graham, said: “Navigator is delivered via hardware designed to withstand harsh industrial environ- mental conditions such as vibration, electrical interference, temperature, and humidity. High visual correlation between the touchscreen and machine function ensures an intuitive user experi- ence that enables both new and experienced operators a rapid learning curve and ease of use.” The company will display a 2.5in (63.5mm) American Kuhne Ultra extruder with XC100 Navigator control, and a 3.5in. (99mm) machine with XC200 Navigator control. Graham has made several improvements to make maintenance simple and accessible. Serviceability features include re-designed barrel covers that allow for quick and easy access to barrel heaters and thermocouples, and an automotive-style wiring harness with quick change plugs for routing wiring and thermocouples between the electrical cabinet to the barrel heating and cooling zones. There will also be a tri-layer medical tubing line, consisting of modular micro extruders and XC300 Navigator with integrated TwinCAT Scope View high speed data-acquisition system. � www.grahamengineering.com


Guill Tool will showcase Bullet II – an extrusion head with a number of innovative features. First, it has no hardware –


that is, nuts and bolts – which makes for easy cleaning, says the company. This feature has been retained from the original


Bullet, but this latest version also allows quick tooling changes, as the tips remove from the back and the die


removes from the front of the unit. The absence of fastening hardware


eliminates leaking, as does the taper body and deflector design, says Guill. Additionally, the new patent pending Cam Lock deflector retaining system offers more benefits to
