Dexell Composites (Keller, Texas, USA) has continued its development of equipment for process control of infusion (see CT’s coverage of Dexell in “The Evolution of Infusion,” in the August 2012 issue, p.28). Company principal and former Lockheed Martin manufacturing group manager Russ Emanis has designed and developed the trademarked ProFusion system, for improved control during repetitive manufacture of composite parts with infusion, double bag infusion, resin transfer molding (RTM) and TRM Lite processing. The new and cost-effective equipment provides for precise proportional delivery of resin and hardener, eliminating waste.

The equipment controls every aspect of the infusion process and includes real time monitoring features. Included software has process programming capabilities and “learn mode” for prototype processing, as well as recipe storage and data logging. The software can also track resin usage against projected consumption and can calculate required tubing. A basic system includes two pumps, which work with varying resin systems, including ester and epoxy, with programming capabilities. Pump designs are available as high-tolerance “gear in a floating gear,” lobe pumps for heavier materials, and precision peristaltic, to meet customer requirements. Other features include a container for cavity control of infusion; onboard resin filtration system; single controlled vacuum regulator; two motor controllers; two computers; a tough screen that stands up to shop conditions;  vacuum controls program; static mix head; and  ten feet of resin and hardener hoses. Additional options are available including a third pump for promoting, and a double control vacuum regulator.

Emanis will be discussing infusion processes and demonstrating the ProFusion equipment at the upcoming 2014 EAA AirVenture air show in Oshkosh, Wis., July 28-August 3. For additional information, call 817-948-6267 or Email: ProFusion58@gmail.com.
