Negri Bossi Launches New Range of Mid-Sized Presses At last month's Plast 2018 show in Milan, Italy, Negri Bossi (U.S. office in New Castle, Del.) introduced additions to its Nova range of injection machines. The company already had introduced the Nova e all-electric line—in Italy about a year ago and at the recent NPE2018 show for North America (see May Keeping Up). That double-toggle series comes in sizes from 50 to 450 metric tons. The new Smart Flex 2 double-toggle clamp has generous tiebar spacing and a moving platen that rides on linear bearings. Its new Tactum control accepts multi-touch commands and is ready for the company's Amico 4.0 wireless remote service access. What's more, Nova e presses boast higher injection speeds—300 mm/sec standard and up to 600 mm/sec on smaller models— for packaging and medical markets. (The company has prototyped up to 1000 mm/sec.) At the Milan show, Negri Bossi brought out the Nova s and Nova i lines. Nova s (pictured) is a servo-hydraulic series; Nova i is a hybrid version (electric clamp and screw drive, plus hydraulic accumulator for injection and carriage movement). Both have a new X-design toggle clamp from 700 to 1150 m.t. This toggle design is said to be unusually compact, with "best-in-class" tiebar spacing, up to 16% greater stroke than earlier models, and "vastly increased" platen speeds. Replacing the Vector series, the new models also boast up to 35% faster injection and over 15% greater injection-pressure capability. The new Motus controller has a 21.5-in. screen with multi-touch capability, including swipe, scroll and zoom functions. It is also fully customizable and is ready for remote service access. A new automatic filtered lubrication system is closed-loop and reportedly leak-free. This is said to be unusual as a standard feature. Negri Bossi says the new machines will enable it to enter new market areas. Both larger and smaller models will be added in future. 302-328-8020 • negribossi.us Trendelkamp, Alpharetta, Ga., introduced a new masterbatch pellet classifier with quick-release screens at NPE2018. The TK-K pellet classifier requires no tooling for screen removal or replacement, easing material and color changes. The unit features a unique oscillating movement that prevents pellet bounce and can efficiently classify a variety of sizes and shapes. Multiple versions are available for collecting oversize, undersize, and properly sized pellets. Throughput ranges are available from 770 to more than 11,000 lb/hr. 770-931-9199 • trendelkamp.com BLOW MOLDING COMPOUNDING MATERIALS INJECTION MOLDING Quick-Change Pellet Classifier During the recent Plast 2018 fair in Milan, Italy, ST Blow Molding showed off its latest hydraulic accumulator- head machines at its plant in Monza, Italy. The company introduced the model ASPI 150.3 Duo, which has a single extruder and head that feed two independent 22-ton clamps. Like the ASPI 400 model exhib- ited at NPE2018 in Orlando, Fla., this unit is designed for 3D suction-blow molding of long, complex shapes, but it can also be used for conventional 2D molding. Also new is the ISIT 200 for 2D blow molding, the smallest unit in the series (22-ton clamp). The unit shown had a 4 L accumulator head. This series uses a three-platen clamp, in which force is applied to the rear of each platen by a crossbeam. This is said to avoid unbal- anced application of clamping force and also accommodates oversized molds. +39 039 2706234 • st-blowmoulding.com High-Impact, FR-PET A specialty UL 94V-0 flame-retardant PET compound that exhibits high dura- bility and high chemical resistance has been introduced by PolyVisions, Manchester, Pa. DuraPET FR, is a graft- modified PET compound designed for molded housings and enclosures in medical devices and lab instrumenta- tion; it is also suitable for film and sheet extrusion. The new compound boasts tempera- ture resistance from -40 F to over 180 F. PolyVisions designed it with enhanced chemical resistance to withstand continuous exposure to germicidal cleaning compounds that destroy the properties of other commonly used thermoplastics. It is reportedly easy to mold due to its low shrinkage and excellent heat stability and is currently used in parts weighing from 20 lb to less than 1 oz. According to the company, molders have been able to use it in molds designed for PC/ABS and other materials. PolyVisions also announced a version of DuraPET FR made from recycled PET. The company claims that its reactive extrusion process allows it use post-consumer regrind PET for up to 90% of the formulation. 717-266-3031 • polyvisions.com New 2D & 3D Blow Molders From Italy AUTOMATION Mecademic, Montreal, displayed a six-axis industrial robot small enough to fit in your hand at last month's ATS East show in N.Y.C. The Meca500 handles payloads up to 500 g (1.1 lb) with what the company calls "unmatched accuracy" of 0.005 mm. There is no proprietary programming language to learn, only a simple set of instructions, says Mecademic. Available since 2016, the Meca500 has been used for testing, inspection, micro-assembly, dispensing, and transfer of materials in confined spaces. 514-360-2205 • mecademic.com Six-Axis Robot Fits In Your Hand 50 JULY 2018 Plastics Technology PTonline.com Keeping Up W it h Technolog y
