WEDNESDAY NPE 2018 : THE PLASTICS SHOW SHOW DAILY Tinius Olsen is showcasing its new scalable, fully automated roboঞc tesঞng system for the first ঞme ever. TINIUS OLSEN, BOOTH W72 12 NPE2018 New Technology Focus What's New in Single-Screw Extruders Davis-Standard's Super Blue extruder series is featured with the firm's newest touch-screen controller. By Jim Callari Plascs Technology Davis-Standard (Booth W5947) is running a TPE tubing line that shows the benefits of prevenঞve and predicঞve maintenance as part of a global trend toward the "smart fac- tory." The line is processing TPE tubing for industrial applicaঞons and features the com- pany's newest Thermaঞc extruder design along with the DS eVUE II controller. D-S is also showing a next-generaঞon 2.5-in., direct-drive, grooved-feed extruder featuring its proprietary Helibar design. The Helibar design is also said to be advanta- geous in terms of higher throughput, im- proved melt-pressure buildup, lower melt temperatures, improved melt homogeneity, reduced barrel wear, and shorter residence ঞme. This extruder is said to be suited for pipe, profile, sheet, and blow molding. The Super Blue extruder line is also fea- tured at the show. D-S says this extruder series offers processors the ability to switch among D-S feedscrews while offering low noise, a double-reducঞon gearbox, minimal maintenance, and consistent producঞon rates. It is available in sizes from 2 to 4.5 in., each with the opঞon of a 24:1 or 30:1 L/D. At the booth, the Super Blue is equipped with the DS-eTPC II, the second generaঞon of Davis-Standard's touch-screen control. Graham Engineering Corp. (Booth W2743) is displaying a 2.5-in. (63.5-mm) American Kuhne Ultra extruder with XC100 Navigator control, and a 3.5-in. (99-mm) extruder with XC200 Navigator control. Graham has made improvements to its Ultra extruders to sim- plify maintenance. Examples are newly de- signed barrel covers that allow for quick and easy access to barrel heaters and thermocou- ples, and an automoঞve-style wiring harness with quick-change plugs for rouঞng wiring and thermocouples from the electrical cabi- net to the barrel-heater/cooling zones. Graham is also showcasing an American KuhneGraham Kuhne three-layer medical tubing line, consisঞng of modular micro ex- truders, an American AKcent coextruder, and XC300 Navigator with integrated TwinCAT Scope View high-speed data-acquisiঞon system. Newcomer US Extruders (Booth S32133) is showing a new generaঞon of highly engi- neered, custom single-screw extruders. On display are 2.5-in., 24:1 and 3.5-in., 24:1 ex- truders, as well as a compact custom medical extruder. The 2.5- and 3.5-in. extruders fea- ture a unique heater-shroud design made of individual stainless-steel shrouds that pro- vide quick access to each zone. Dual-layer stainless steel keeps the exterior relaঞvely cool to the touch. Thermocouples go through the side for easy replacement. Each shroud includes an adjustable exhaust deflector. Integral wireways are also built in to provide a clean look and easy access to wires. The machines on display also have a C-clamp with an easy-open, over-center lever and thumb-release safety lock. A compact custom medical extruder at the booth includes a servo drive, swappable bar- rels, washdown design, integrated control cabinet with special die-wiring management and other special features designed for the medical and pharmaceuঞcal industries. The machine has swappable barrels in 0.50-, 0.75-, and 1-in. sizes. New from Milacron Extrusion Technolo- gies (Booth W2703), the SV350 is billed as a robust and flexible extruder suited for pro- cessors of profile, tubing, sheet, fiber, wire and cable. The SV350 is available in sizes from 2 to 4.5 in. with 24:1 L/D. As a stock machine, it is available for quick delivery. The solEX NG from Ba•enfeld-Cincinnaঞ (Booth W2771), offers up to 20 percent higher outputs, up to 15 percent lower ener- gy costs, and approximately 15-20° F lower melt temperatures, the machine builder says. Lower melt temperatures allow polyolefin pipe producers to either shorten the length of their downstream cooling system or main- tain the same length to boost output by as much as 20 percent. Canon Virginia is doubling up the injecঞon molding acঞon in its booth (W223), running two separate tools in one machine simultaneously. Using a customized Sumitomo (SHI) Demag press, the Mulঞ-Mold System works by injecঞng into the first mold, which then slides out from between the platens to cool outside the machine. While this happens, the second mold slides in for injecঞon, before giving way to the first tool which reenters the press for part ejecঞon. Canon says this transforms idle cooling ঞme into producঞve molding ঞme by shu•ling a second mold into producঞon. Canon Virginia Increases Producঞon Output by Using Two Molds in One Machine 3D-Printed Conformal Cooling Backed by Linear AMS Experঞse By Stephanie Hendrixson Addive Manufacturing "One of the best uses of addiঞve manufacturing is in tooling," says John Tenbusch, founder and president of Linear AMS, a Livonia, Michi- gan-based injecঞon molder and mold manufac- turer. As an early adopter of metal 3D prinঞng technology for conformal cooled inserts, Linear has the experience to back up this claim. Following a brief sঞnt under the majority ownership of Moog (a manufacturer primarily serv- ing the aerospace industry), the company is back under Tenbusch's leadership and recommi•ed to injecঞon mold tooling and low-volume parts manufacturing. Linear's technical skill and know-how in these areas are on display throughout NPE2018. Founded in 2003 as Linear Mold and Engineering, the company has years of experience in using laser-based pow- der-bed addiঞve manufac- turing (AM) to 3D print con- formal cooled inserts. These complex pieces, with cooling lines that twist and curve to follow the contours of the mold, can speed the injec- ঞon molding process and improve part quality. As both a tool builder and injecঞon molder, Linear AMS has seen the benefits firsthand. "Conformal cooling in injecঞon molding is a no-brainer," says Lou Young, Linear president. But what isn't so obvious is how to design and manufacture those conformal cooled inserts. That's where Linear's experঞse comes in. Creaঞng conformal cooled inserts involves more than just hiমng "print" on an addiঞve machine. The process first requires analysis and engineering to design an effecঞve insert, as well as material knowledge and experঞse in the AM system used to produce it. Developing the knowledge to do this requires a substanঞal amount of ঞme and money in R&D. "We've already been down that road," says Tenbush, adding that as a result, the company can run "the whole gamut on tooling," from engineering through 3D prinঞng. (The one service it doesn't offer is finishing, leaving that step up to the tool shops that purchase inserts.) A•endees can learn more about Linear AMS's conformal cooling and low part producঞon capabiliঞes in Booth S23160. Linear AMS specializes in designing and 3D prinঞng conformal cooled inserts for injecঞon molding. In addiঞon, Lou Young, Linear AMS, is pre- senঞng "The Greatest Impact of AM: Con- formal-Cooled Inserts" today, at 1:45 p.m. during the 3D Prinঞng Workshop.
