WELDING PROCESS COOLING Compact Ultrasonic System Enables Secure Electronic Records Management The latest addition to the Branson 2000Xc series of ultrasonic assembly systems from Emerson's Branson Ultrasonics Div., Danbury, Conn., is the compact Branson 2000Xc 40-kHz Micro Actuator with 800 W output. It is only 70 mm (2.76 in.) wide and 660 mm (25.98 in.) high. The Micro Actuator can be integrated in automation systems or used as a stand-alone. Look for it at NPE2018 in May in Orlando, Fla. The unit locks in the welding process with fully electronic welder settings, hierarchical password protection, and Ethernet connec- tivity access. It can store 100,000 weld histories and 1000 weld presets. The touchscreen system offers secure process controls and detailed weld data to meet the global compliance, traceability, and security needs of today's medical, automotive, and electronics markets. The security feature helps to ensure compliance with medical manufacturing regulations, including FDA 21 CFR part11. 888-282-9353 • emerson.com Variable-Speed Chillers Boast Dramatic Energy Savings After introducing a new line of variable-speed, air-cooled chillers last July, Delta T Systems, Richfield, Wis., is coming out in May with variable-speed, water-cooled chillers of 2 to 30 tons (see May '17 Close-Up). A variable-speed compressor, together with an electronic expansion valve, a modulating control valve, and sophisticated controls are said to provide at least 30% to 50% energy-cost reductions. A 10-ton chiller operating one full shift per day reportedly could pay for itself in energy savings within three years. Integration of variable-speed controls is proven technology but relatively new to process cooling. The number of brands offering this feature is gradually multiplying (see, for example, Keeping Up in June '17, Dec. '17, and Jan. '18). The new water-cooled chillers are said to offer temperature control within ±0.5° F, a stainless-steel and copper brazed-plate evaporator for reduced maintenance, nonferrous chilled-water piping, "the smallest footprint in the industry," and advanced controls that are "ready for Industry 4.0." Learn more about these variable-speed chillers in a technical presentation at Plastics Technology's Molding 2018 Conference, Feb. 27-Mar. 1 in Long Beach, Calif. (moldingconference.com). The new chillers will also be on display at NPE 2018, May 7-11 in Orlando, Fla. 800-733-4204 • deltatsys.com At October's Fakuma show in Germany, Sesotec GmbH ( U.S. office in Bartlett, Ill.) presented for the first time its Protector, Rapid Pro Sense, and GF metal separators with OPC-UA communications protocol integrated into their controls. These systems detect and separate magnetic and non-magnetic metal particles, even embedded within plastic pellets or regrind. OPC-UA (Open Platform Commu- nications-Unified Architecture) is becoming an international standard for "smart factories," or Industry 4.0. With OPC-UA, these metal separators can communicate with central plant computers or directly with injection and blow molding machines and extruders to protect against damage and clogging of mold and die channels. 224-208-1900 • sesotec.us Networked Metal Separators Ready for Industry 4.0 MATERIALS HANDLING 76 FEBRUARY 2018 Plastics Technology PTonline.com Keeping Up W it h Technolog y
