"Kelly Control Systems completed installation of a "Simulated Isothermal Control System on our 1,800-tonne extrusion press in January 1999. Technically it has functioned without problem and operatives now use it on approximately 70% of dies. Press performance has improved and productivity has increased significantly."
Gary Renwick, Chief Engineer, Capral Aluminium, New Zealand.

“In addition to the expected increase in production from closed loop speed control and simulated isothermal extrusion, we found several additional benefits. Dead cycle was reduced by over 20%. Press movements were very smooth. We were so pleased with the first installation that we have modernised 3 more presses and have agreements for two more Kelly Systems.”
John Anning, Extrusion Director, Aluminum Shapes LLC

“The simulated isothermal extrusion resulted in an exit temperature range of less than 15deg F from front to back of billet, resulting in dimensional consistency in the extrusion”
John Anning, Extrusion Director, Aluminum Shapes LLC

“I am absolutely delighted with the way in which this installation has been carried out.  The testing and commissioning methods were extremely logical, and the teamwork between our Hydro employees and yourselves was a pleasure to observe.  The benefits of your equipment are already evident to us, and I’m sure that we will be making every effort to deal with you in the future.”
S.C.Brown, Projects Engineer, Hydro Aluminium

“The upgrade of our 1600 tons Farrel press was carried out very professionally, and completed within the specified time scale.  We are very satisfied with the upgrade project and notice significant improvements in the press operation and performance.”
Michael Rozenfield, Director, Schremer Aluminium Industries.

“La extrusion isotérmica así como los bucles cerrados de posición y velocidad nos permiten obtener velocidades mayores de extrusion sin tener diferencias de calidad de en el material.”

“On January 2008 we installed a new control system by Kelly Control, on our 1650-ton Sutton press. The performance has been improved significantly. The movements are fast but smooth: the response of the pumps is precise: the press is friendlier with many difficult dies: many safety features have been added: operators and maintenance people are very happy with the change.  James Kelly and the staff of people with him were extremely professional.”
Kobi Horesh, Plant Manager, Extal

“Mr. Kelly has completed upgrades on 2 x 1600 Fielding and Platt presses that I have been involved in. Clearly the closed loop speed control delivers a repeatable process which helps not only improve throughput but the general quality of the product - the first installation is now operating at a 5% higher yield than previously. The second - which was recently completed only 4 weeks ago is already realising a 20% improvement - again through dead cycle reduction and closed loop speed control, but also a program mod that times the extrusion ratio to get maximum speed prior to lift off on a press using a  double puller configuration.”
Calvin Carpenter, - Process and Management Control Consultant

“THE CLEARING PRESS IS SMOKING.  THE PRODUCTION INCREASED 10% - 15% IN THE WEEKS AFTER YOU LEFT.”
