Three companies recently introduced equipment and chemicals for cleaning molds and plastic parts: • Laser specialist Fonon Corp., Orlando Fla. (fonon.com), brought out the Laser Photonics CleanTech line of laser cleaning systems in both stationary and portable models. Lasers quickly and selectively remove rust, paint, grease, etc. from metal parts without abrasion or chemicals (photo left). Pulsed infrared laser action affects only a few microns at the surface of the part; once the rust or surface contamination is vaporized by the laser, the underlying metal reflects the laser IR light harmlessly. No debris is left behind. If necessary, the laser can be focused on a small spot. Fonon also introduced Flexion technology, whereby the workpiece is placed on an x-y motion-control stage for thorough cleaning of 3D surfaces. • Omegasonics, Simi Valley, Calif. (omegasonics.com), a maker of ultrasonic cleaning systems for metal and plastic parts, has two new products. One is a pneumatic lift unit to help lift large, heavy metal molds or parts in and out of the cleaning tank. Power- Lift 4560 is a cleaning system with a 120-gal tank (38 x 29 x 19 in.) and lifting device (photo at left). Second is Omegasonics' new Omega- Supreme Soap 40, an ultrasonic cleaning detergent that is said to remove oils, light grease, dirt, carbon, etc. from metals and plastics. It is said to be safe for use with a wide variety of metals and plastics. • IMS Company, Chagrin Falls, Ohio (imscompany.com), offers two new spray-on cleaners for injection molds. Both are low enough in toxicity to avoid labeling under California's Proposition 65 program. IMS C-Foam foaming citrus mold cleaner creates a drip-resistant foam that remains in place for minutes while it dissolves grease and contaminants. The biodegradable, citrus-based foam is not flammable and is suited to use where fast evaporation is not required. Where fast evaporation is desired, new IMS LT-65 is a low-VOC spray that meets California standards. It provides very good and fast cleaning ability where a flam- mability hazard can be managed. 1(905)507-9000 I sales@macroeng.com I service@macroeng.co I www.macroeng.com Mississauga, ON, Canada Newest MacroPack-FP Die Fastest Purge Time Most Versatile Up to 13 layers Up to 30 layers Moldmaker StackTech of Brampton, Ont., has added servo-drive capability to its high- cavitation molds. The company has built two servo-driven unscrewing molds for clean-room use. The servo molds use belts and pulleys and a sealed drive system. Energy consump- tion and maintenance requirements are both said to be less than for an hydraulic rack-and- pinion system; faster cycles and improved part ejection control are also claimed. The mold comes with a caster-mounted control cabinet including a power source. A simple pendant with five buttons is said to provide highly accurate control of unscrewing speed. "Considering that it's available at a very modest premium, we expect servo-driven unscrewing will become the new standard for the industry," says Vince Travaglini, StackTeck's v.p. of sales and marketing. Adds Jordan Robertson, general manager of business development and marketing, "In one case, a single-cavity prototype mold ran with conventional hydraulic technology with an unscrewing time of 1 sec. When we ran the 16-cavity production mold, the unscrewing time (with servo drive) was reduced to 0.3 sec." 888-700-8555 • stackteck.com New Equipment & Chemicals For Mold & Parts Cleaning Servo-Driven Unscrewing Molds with High Cavitation TOOLING TOOLING Before After 74 APRIL 2017 Plastics Technology PTonline.com Keeping Up W it h Technolog y
