New LEC Controllers Feature High Performance, Competitive Pricing for up to 24 Zones of Control
K 2004, Dusseldorf, October 20-27 - Hall 10, Stand H48

Sterling, VA (October 20, 2004) . . . Gammaflux will display its newest line of hot runner temperature controllers at K 2004 in Dusseldorf, Germany, October 20-27 (Hall 10, Stand H48). The new LEC line of temperature controllers provide molders with full-featured hot runner temperature control at an extremely competitive price.

Designed for smaller hot runner system applications, the LEC is offered with 2, 6 and 12 zone enclosures. The LEC features a modular design for simple control card removal, addition or replacement. An optional network module allows users to link two 6 or 12 zone enclosures together for up to 24 zones of control. All 6 and 12 zone LEC enclosures come prewired to accept the network module, so the module can be ordered up front or added at a later date.

With the addition of the network module, the LEC becomes truly full-featured by offering security options, remote input, alarm output, and Gammaflux software including Gammavision, Mold Doctor and Field Calibrator (with a customer supplied laptop or personal computer). The network module also enables a link to plant monitoring systems.

Flexibility has been built-in to the LEC line for global use. It is designed to work with most hot runner molds operating in the world today.

All LEC controllers are backed by a complete two year warranty and supported by the worldwide Gammaflux service and support network. They can be ordered through Gammaflux sales representatives or online at www.gammaflux.com. The Gammaflux web site has been updated to allow users to completely configure a standard or custom system for easy, immediate ordering capability.

"We see the LEC as a true breakthrough in hot runner controller performance and affordability," said Mike Brostedt, Gammaflux Director of Market Development. "It provides field-proven Gammaflux quality and reliability at a much lower price. No longer do molders have to pay a high price to get high quality hot runner temperature control."

Triangulated Control TechnologyTM - The Gammaflux Advantage

Like all Gammaflux hot runner temperature controllers, the new LEC line features Triangulated Control TechnologyTM. Using this unique technology our controllers:

• Sense - 20 times per second, Gammaflux controllers precisely measure the thermocouple;
• Control - the proprietary self-optimizing Gammaflux PID2 control algorithm adjusts if the actual temperature deviates 0.1°F (0.05°C) from setpoint. The second derivative (PID2) monitors the actual temperature rate of change. As a result, the LEC module regulates the output to the heater in advance of achieving setpoint to limit or eliminate over or undershoot.
• Actuate - using phase angle fired output, the Gammaflux controller delivers smooth and exact power to each heater in 0.24 VAC increments for the ultimate in temperature control.

By "triangulating" their process with Gammaflux, molders can achieve better hot runner temperature control, which can mean:

• enhanced part quality
• reduced scrap
• improved part weight consistency
• material savings
• higher profit margins

In addition, Gammaflux controllers feature mold protection through closed loop wet heater bakeout. 120 times per second (at 60 Hz), Gammaflux controllers check every heater for a short, steadily ramping up the voltage for the fastest possible time to setpoint. If the heater is wet or shorted the output is adjusted within 8.3 milliseconds to protect the heater, cables and controller.
