Chen Hsong is offering several new lines of machines, not all of which were at the show. The Jetmaster MK6 line of servohydraulic toggle presses comes in 88 to 668 m.t. The clamp, base, and injection blowing machine unit have all been redesigned and beefed up. Also redesigned is the Jetmaster Large SVP/2 series from 650 to 3000 m.t. New Evolution MK6e servohydraulic toggles (90 to 650 m.t.) are a lower-cost version said to be suitable for 80% of the market. The powerpack has been downsized somewhat, so these machines are not optimal for high-volume or high-torque production. There’s also a smaller new low-cost line, Focus SVP/2 from 20 to 60 m.t. At the higher-performance end is the new Speed series of servohydraulic toggles (128 to 468 m.t.) with a “top-of-the-line,” high-response servomotor for ultra-high-speed injection. The related new Speed-Pack series (260 to 470 m.t.) has longer screws, up to 26:1 L/D. Finally, a new all-electric series is the Spark line from 100 to 230 m.t., boasting a more compact and more open design.
Fanuc has a new standard execution for medical Roboshot machines, including such features as stainless-steel construction, special screws, HEPA filter, and new “bush-less” tiebars.
JSW introduced its patented SOFIT foam injection technology. It involves injecting nitrogen gas into the barrel in a decompression zone after the melting zone and before the metering/compression zone. A special screw and barrel are required, but a cost-saving feature is the ability to feed nitrogen directly from a storage tank via a pressure-reducing valve, with no need for a high-pressure metering pump.
KraussMaffei showed the new Netstal Elios 4500 (450 m.t.) high-speed, hybrid toggle press. The series was launched at NPE2018 with a 750-tonner, which is now supplemented by models of 450, 550, and 650 m.t. Also new was a 21.5-in. multi-touch display on the KM CX 80 hydraulic machine with a PLC control based on the KM MC6.
