New Systems for Eliminating Static

Web Systems, Inc. (Boulder, CO) has recently introduced two new technologies for enhanced control and elimination of static charges from various plastics processing methods.

The Avalanche 200 Feedback Ionization system is the first completely automated self-monitoring static eliminating system for plastics applications, according to the company. The Avalanche 200 provides easy self-monitoring and fault detection circuits that continually display detailed function analysis of static bar, generator and ionization status. The product’s feedback technology targets multiple plastic applications, including extruding, high-end converting, blowmolding, casting, compounding and sheeting.

The Ion Storm 200 Electrostatic chill roll tacking system is a completely automated turn-key solution for increasing throughput rates of film lines by 40 percent, Web Systems claims. The system’s pinning bar set-up tacks plastic substrates to the chill roll while being extruded, converted or printed. A special stainless steel blade in the bar creates a strong electrostatic field; the charge is distributed equally over the web, causing the film to be temporarily bonded to the chill roll surface, improving the heat transfer between the chill roll and the film.
