Extrusion systems, and one control to rule them all, featured by Graham Engineering at K 2019

American Kuhne medical extruder
Originally developed by Graham Engineering (York, PA) for its extrusion blow molding systems and then adapted for sheet extrusion lines, the Navigator controls are now available for American Kuhne extrusion systems.

Graham Engineering Corp. (York, PA) will exhibit several extrusion systems at stand A 71 in hall 16, but the real star of the show will be its Navigator control system. Originally developed for Graham Engineering’s extrusion blow molding systems and then adapted for sheet extrusion lines manufactured by Welex, which it acquired in 2013, the Navigator controls are now available for American Kuhne extrusion systems, also part of the Graham portfolio since 2012, that process medical tubing, profiles, wire and cable.

An American Kuhne medical extrusion system equipped with Navigator control technology will be on display at stand A 71 in hall 16.

Graham Engineering will be doing live demos of its Navigator control technology on various pieces of equipment during K 2019 in Düsseldorf, Germany, from Oct. 16 to 23. The system uses an industrial PC with a Windows platform to provide intuitive, integrated extrusion process control. Real-time graphical display is a hallmark of Navigator control, noted Graham Vice President of Engineering Justin Kilgore.

“High visual correlation between the touchscreen and machine function ensures an intuitive user experience that provides ease of use and a rapid learning curve for both new and experienced operators,” said Kilgore. “Powered by a friendly, open architecture that allows a high level of flexibility, Navigator control is delivered via hardware designed to withstand harsh industrial conditions such as vibration, electrical interference, high temperature and humidity.” Easy, expansive integration is a key feature of the system, he added. “From synchronized supervisory control of a line to its open architecture that supports connectivity for data collection systems to internet for remote support and trouble-shooting, Navigator offers integration without limits,” said Kilgore.

Navigator controls are available in three levels of functionality: The 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.

Extrusion systems on display at the Graham Engineering Corp. booth will include:

  • American Kuhne medical extrusion systems, including ULTRA MD systems, compact modular extruders and a tri-layer tubing line with the XC300 Navigator control and integrated TwinCAT Scope View high-speed data- acquisition system.
  • Revolution MVP rotary wheel blow molder, which combines high-output molding with the flexibility to produce a range of package sizes and quick mold changes. A key innovation is the independence of each clamp station, with all forces self-contained within the clamp. Water manifolds through the platens facilitate quick mold change, and individual clamps can be removed for offline maintenance to reduce downtime. This modularity enables the user to vary the number of clamp stations from 12 to 24 on the same platform and configure the wheel based on the application and bottle height.
  • Welex Evolution sheet extrusion system, a complete production line for use in sheeting, winding and in-line thermoforming applications, equipped with XSL Navigator control. The equipment on display at K 2019 will be for thin-gauge polypropylene, but the Evolution system can be customized to accommodate widths from 36 to 90 in. (90 to 230 cm), gauges from 0.008 to 0.125 in. (0.2 to 3.2 mm) and throughputs up to 10,000 lb/hr (4,535 kg/hr).
