THURSDAY NPE 2018 : THE PLASTICS SHOW SHOW DAILY Milacron Hauls Two Huge Molding Machines to Orlando for Display In the same booth, Milacron is displaying a recreaঞon of a single platen from a machine it's building for 20/20 Custom Plasঞcs, Holiday City, Ohio., which when completed will have nearly three ঞmes the clamping tonnage of the 2,250-ton Cincinnaঞ—6,600 tons. 14 Not Running, But Sঞll Pushing Technology Envelope in Film Extrusion TurboClean retrofits pay off for film processors who do lots of product changeovers and even those who are more interested in pounds, notes Andrew Wheeler, president of W&H. In both cases, the technology increases upঞme. By Jim Callari Plascs Technology Used to be, you'd see about as many running blown-film lines at NPEs as you would at the K Show. But while many builders of blown- film lines sঞll operate systems at the giant triennial show in Dusseldorf—some more than one—most have scaled things back where NPEs are concerned, ciঞng the cost of resin and power, as well as the "impracঞcali- ty" of how to dispose of finished rolls. But that's not to say there aren't some interesঞng things to see and talk about in Orlando. In the case of Windmoeller & Hoe- lscher (W&H) Corp., (Booth W6663), retrofits are a big theme. The company has made its revoluঞonary TurboClean technology auto- maঞon module retrofiŽable to some exisঞng W&H lines. The TurboClean system purges resin from all extruders and gravimetric hop- pers simultaneously, dramaঞcally decreasing the ঞme required to change materials. It was introduced at an open house W&H held at its Lengerich, Germany, headquarters in mid- 2015, then officially unveiled at K 2015, but was available only on new W&H Varex II systems. But now, exisঞng W&H Varex II and Varex I lines built in or a[er 2010 can be retrofiŽed with the module, allowing blown film proces- sors to benefit from significant cost savings via faster job changes. With TurboClean, ma- terial changes are almost completely auto- mated. Operators no longer need to manually purge resin one extruder at a ঞme. Instead, the steps are automated and run simultane- ously, requiring the operator only to change the sucঞon wand from one resin port to the next. This system is said to reduce the ঞme it takes between product changeovers from 30 min to an astounding two min. "W&H commercialized the industry's first automaঞc gauge-control technology in the late 1980s with the Opঞfil P system, and the TurboClean is yet another example of our efforts to take scrap out of the blown-film process," states Andrew Wheeler, president of W&H Corp. Some film structures contain not only mulঞple layers, but each layer can be comprised of a half dozen or more different material components. "Smaller companies in parঞcular—film processors with three to five lines—will get a very quick return on invest- ment on TurboClean," Wheeler states. "If they do shorter runs and make mulঞple changes a day, TurboClean will pay off very quickly." But the technology is also suited to larger-sized processors with much longer run ঞmes. "These film processors are concerned about pounds, pounds, pounds," says Wheeler. "They might do one or two changes a day. But by compressing the ঞme between changes, they are freeing up machine ঞme and might be able to fit in another order." Wheeler reports that W&H has lines equipped with TurboClean installed (or on order) in North America. Wheeler also notes more processors are invesঞgaঞng mid-size Machine Direcঞon Orientaঞon, improving properঞes by adding 5-10% stretch post-processing. On the mat- ter of Industry 4.0—or Packaging 4.0, in W&H's parlance—Wheeler notes Filmex II cast film lines are being furnished with its recently introduced Film Performance Moni- tor (FPM). "We've been pushing the idea of networking machinery for a long ঞme in extrusion, and we're seeing more customers gearing up for it. FPM integrates data from the extrusion line with downstream convert- ing equipment, allowing these two previously discrete operaঞons to be networked to im- prove quality and make the enঞre producঞon process seamless and traceable." It's All About Speed at Sumitomo (SHI) Demag Sumitomo Demag SEEV-A all-electrics are present at the show in the full size range from 50 to 500 metric tons. By Mahew H. Naitove Plascs Technology Sumitomo (SHI) Demag (Booth W3045) has brought 12 machines to NPE, eight of them in its own booth and four in others'. Seven of the 12 are members of the latest SEEV-A all-electric toggle line, spanning the full size range (56 to 562 tons) of this plaorm. The larger models are aimed in part at automoঞve molders, due to their ability to carry larger, heavier and more complex molds than some electric machines in the past. At the show, SEEV-A machines are running medical and packaging applicaঞons, as well: • Molding eight thin-wall medical dosing cups in 3 sec. • High-speed molding of medical pipeŽes in 32 caviঞes. • Injecঞon-compression molding with IML to produce a thin-wall food-container lid on a 4-sec cycle. • Molding a vacuum-cleaner fan compo- nent with fast color change. In addiঞon, an El-Exis SP 300 ultra-high- speed hybrid is running 72 high-precision water caps on a 2-sec cycle. Sumitomo Demag also is demonstraঞng micromolding of a DNA-free, high-clarity sample collecঞon tube with a wall thickness of 0.250 mm. Tasked with filling an 18,700 [ 2 booth (W2703), Milacron made its job simpler by hauling two massive pieces of equipment to Orlando. First up, a 2,250-ton two-platen Cincinnaঞ press molding a side-by-side dashboard for an ATV.
