TUESDAY NPE 2018 : THE PLASTICS SHOW SHOW DAILY High-Speed Packaging Demo from Netstal Leistritz Pushes 'Technology Envelope' in NPE2018 Display Consistent with its strategy of looking at emerging technologies outside its core business, Leistritz President Charlie Marঞn is showing a line to produce filaments for 3D prinঞng. By Jim Callari Plascs Technology For Leistritz, NPE2018 is not just about dis- playing its new machinery and process-devel- opment capabiliঞes. Over the past several shows, in fact, the firm has deliberately dis- played products outside the realm of its core technology of twin-screw compounding ex- truders. Charlie Marঞn, the company's president and general manager, explains why: "Our displays are what I would call 'forward look- ing.' We look at the bigger picture, try to idenঞfy technology developments that are around the corner, and make decisions on what to display at the show based on that strategy. We plant seeds, and in ঞme many come to fruiঞon." 1- to 5-mm 3D filaments; and a custom air- rack for air quench cooling and sizing of the filament, belt puller, laser gauge and winder. The control system will integrate closed-loop pressure control to ensure a ঞght tolerance product. Marঞn says the system is ideal for in-line compounding of polymers with addi- ঞves and acঞve-fillers to quickly develop new filaments and formulaঞons. Formulaঞons can be modified "on the fly" for rapid sampling of modified filaments with different formulaঞon percentages. A sample can be produced every 10 minutes. A[er the show, Leistritz will ship the line back to its process laboratory in Somerville, New Jersey, where it will be available for trials. Leistritz's display of its ZSE 27 MAXX co-rotaঞng twin screw extruder is yet another 'Sumitomo's Theme: Producঞvity + Flexibility + Reliability John F. Marঞch III, execuঞve vice president and COO of Sumitomo (SHI) Demag's U.S. operaঞons. By Mahew H. Naitove Plascs Technology "Our theme for the show is 'Producঞvity Plus.' Why the 'Plus'? Because it's not enough for our machines to be fast—there are other fac- tors our customers need for success," says John F. Marঞch III, execuঞve vice president and COO of Sumitomo (SHI) Demag's U.S. operaঞons. Marঞch says the "Plus" factors include Flexibility, Technology, Automaঞon, and Reliability. Flexibility is a big one for Marঞch. It rep- resents his machines' capabiliঞes for a broad range of molding tasks. "It's rare today for a molder to serve just one market, like automo- ঞve, packaging, or consumer products. Be- cause we have a broadly capable electric ma- chine plaorm, and one control plaorm for all our machines, it makes it easier for those machines to serve a variety of markets." Sumitomo Demag makes this point by op- eraঞng four machines from its SEEV-A all-electric line (out of six total) in its booth (W3045)—and six others at partner booths throughout the show—molding medical, auto- moঞve, packaging, and consumer-products applicaঞons. These machines span the full size range for that line, from 50 to 500 metric tons. tent filling of long-flow parts, family molds, or other unbalanced tools. Another specialized technology that the company is demonstraঞng is a fully automat- ed, fast color-change process, including QC inspecঞon, from Cam Co., Ltd., a Japanese molder and moldmaker. It is being used on a 50-ton SEEV-A press molding a small vacu- um-cleaner fan blade. "We're also showing an automated clean- room cell for producing a DNA-free medical sample collecঞon tube. A[er the show, this machine will go to Makuta Inc. in Shelbyville, Indiana, where it will run lights-out with 'hands-off' inspecঞon, QC, and packaging," states Marঞch. That micromolding applica- ঞon uses a 30-ton SE-DUZ all-electric press. Of course, if it's naked speed you're look- Ten Sumitomo Demag SEEV-A all-electric machines are running at the show, four of them at Sumitomo Demag's booth, and six at partner booths. They span the full size range for the series, from 50 to 500 metric tons. "It's rare today for a molder to serve just one market, like automove, packaging, or consumer products. Because we have a broadly capable electric machine plaorm, and one control plaorm for all our machines, it makes it easier for those machines to serve a variety of markets." Another meaning of "flexibility" for Marঞch is the ability for Sumitomo Demag machines to handle higher cavitaঞon, thinner walls, and ঞghter tolerances, especially when that means a smaller machine can take on a job that normally requires a larger press. "Take a long-flow automoঞve part that might normally run on a 600- or 700-ton machine. Thanks to our wider ঞebar spacing and Mini- mum Clamping Molding (MCM) technology, that part can run on one of our 500-ton all-electric machines, and perhaps use only 300 tons of actual clamp force." Two more of Marঞch's "Plus" factors are Technology and Automaঞon. "We supply technology and automated cell soluঞons that can take molders to the next level," he says. Examples at the show that he points out are an automoঞve part that is lightweighted with an unusual combinaঞon of gas assist and chemical foaming on a 500-ton SEEV-A press. That machine uses Sumitomo's Flow Front Control technology to ensure consis- ing for, Sumitomo Demag has pulled out the stops with a 300-ton El-Exis hybrid press running 72 bo•le caps in a 2-sec cycle. "That's the real eye-opener at the booth," enthuses Marঞch. But there's more: a 180- ton SEEV-A press that's injecঞon-compres- sion molding thin-wall lids in two caviঞes with IML in 4 sec; and a 130-tonner molding medical pipe•es in 32 caviঞes in 7 sec. An addiঞonal "Plus" factor is Reliability. "That's a hard one to put into a few words," muses Marঞch. "But take this example: A cus- tomer called me asking for addiঞonal opera- tor training—or retraining—on a press they had been running for over a year. They told me that in all that ঞme they had so li•le need to adjust any seমngs that the operators had simply forgo•en how." The other booths where Sumitomo Demag SEEV-A machines are running are Yushin (W2173), RJG (W3383), Gammaflux (W643), and Canon Virginia (W223), which has three presses running. NPE is the U.S. debut of the Elios hybrid toggle line from Netstal (Booth S16088). A 750-m.t. ex- ample of this high-speed press is molding 16-oz deli containers (473 ml) from an 8 + 8 stack mold in a 3.1-sec cycle. The new "lightning-fast" toggle clamp reportedly provides "the fastest dry cycle in its size class." The five-point toggle is designed to provide force in the center of the mold to prevent any deformaঞon of the mold plates. It also boasts "very large" ঞebar spacing and "ex- tremely ample opening stroke," suiঞng it to stack molds. The clamp features electric traverse and hydraulic pressure buildup; screw drive is also electric, while injecঞon is servo-hydraulically driven for speeds up to 2,200 mm/sec, acceleraঞon up to 20G, and reacঞon ঞme of 11 millisec. Live producঞon at the Netstal Krauss- Maffei booth: 16 oz. delicatessen containers will be produced on a Netstal ELIOS 7500 At previous NPE shows, Leistritz (Booth W5545) has displayed a TPO-based coextru- sion sheet line that combined a single-screw machine and a twin, as well as mono-layer lines for sheeঞng and medical tubing. At that ঞme, in-line compounding—combining twin- screw compounding with finished-part extru- sion—was in its infancy, and Marঞn wanted Leistritz to "push the envelope" and be ahead of the game. At other NPE shows it displayed a line for super-criঞcal CO 2 microcellular foaming. At its booth at NPE2018, Leistritz displays a line to produce filaments for 3D prinঞng— also known as addiঞve manufacturing. The system consists of loss-in-weight feeders; a ZSE 18 co-rotaঞng twin screw extruder fur- nished with a gear pump; a die to produce example of the machine builder's "outside the box" thinking with respect to exhibiঞng at trade shows. This line is shown with an air- quench pelleঞzer. "Now, maybe one out of every 200 twin-screw compounding systems are specified with this type of pelleঞzing sys- tem," says Marঞn, explaining that the technol- ogy is used primarily in cases where the com- pound must avoid water. "Compounders use air-quench pelleঞzing only if they have to," says Marঞn. "They tend to be more difficult to operate. The pellets tends to clump, smear and sঞck together. But we're seeing more formulaঞons being developed that require this type of technology, parঞcularly in the area of biopolymers. And if you happen to have this type of pelleঞzing technology, you'll be in the posiঞon to get the orders." 14 NPE.ORG A PRODUCT OF PLASTICS INDUSTRY ASSOCIATION
