NPE2018 was rich in new molding, extrusion, and thermoforming hardware and technology. Much of this was reported in our April and May issues (including the five Show Dailies). Nonetheless, our editors vacuumed up enough additional news to require two more issues to present it all. But for the full picture of all that was on display in Orlando, go to the NPE2018 Zone at PTonline.com to explore the wealth of ear- lier reports on new technology. INJECTION MOLDING NEWS Our previous coverage included new and enhanced injection presses from Arburg, Bole North America, Boy Machines, Chen Hsong, Engel, Fortune International, KraussMaffei, Führung/ Leadway, FCS/Maruka, Md Plastics, Milacron, Negri Bossi, Netstal, Nissei, Plustech/Sodick, Sumitomo Demag, Wilmington Machinery, Wittmann Battenfeld, and Yizumi-HPM. Presented here are additional new entries and more on some machines on which few details were previously available. New machines were overwhelmingly of two categories, all- electric and servo-hydraulic. Within the latter group, a case could be made that the stars of the show were two-platen presses, whose By Matt Naitove, Executive Editor & Jim Callari, Editorial Director Rounding up details from the Big Show not previously reported in all our other coverage, here's more news in injection and blow molding, extrusion and compounding. Next month, we'll conclude with recycling/scrap reclaim, robots, tooling, auxiliary equipment, materials and additives. News in Primary Machinery compact format fits neatly with burgeoning applications for large machines for automotive, recreational vehicles, housewares, large bins, and other medium-to-large parts. Quite a few of these machines at the show hailed from China or South Korea. For example, CH-America, the new representative for Chen Hsong of Hong Kong (ch-america.com), is partic- ularly excited about the new Supermaster servo-hydraulic two-platen series from 700 to 6500 metric tons (7150 U.S. tons). CH-America sources point enthusiasti- cally to platen speeds up to 700 mm/sec— "almost unheard-of" for this type of machine—together with modularity that allows buyers to mix and match 14 clamp sizes and 29 injection units. Clamp speeds up to 1100 mm/sec are claimed for new two- platen lines from LS Mtron, the new name for what used to be Lucky Goldstar and then LG of South Korea (U.S. office in Norcross, Ga.; lsinjection.com). Under an agreement announced at NPE, LS Mtron named Daiichi Jitsugyo America (DJA) as a distrib- utor in the U.S. DJA also distributes Niigata injec- tion machines from Japan (niigata-us.com). Niigata builds only all-electric toggles, however. LS Mtron, the largest injection machine builder in South Korea (2800 machines in the last year), is looking to revitalize its U.S. presence. It offers three series of two-platen presses: the servo-hydraulic WIZ series from 450 to 1100 m.t.; WIZ-X series from 1300 to 4000 m.t.; and the One series of premium two-platen hybrid presses from 500 to 3300 m.t. The last series comes with a one-touch automatic tiebar-pulling system, quick-barrel-change system, and 250% greater mold-weight capacity. PART 1 Servo-hydraulic two-platen machines were among the most numerous new machines on display. This 2250-ton press, part of Milacron's new Cincinnati series, is an example of the dominance of servo-hydraulic two- platen presses among new machines at NPE. QUESTIONS ABOUT NPE2018?
