WEDNESDAY NPE2018 M AY 9 TH 83 ZEISS X-ray family Industrial computed tomography gives you entirely new insights by making it possible to capture the whole volume with all internal structures. With the ZEISS X-ray family, you can successfully perform complex analysis, measuring and inspection jobs with only one scan. Visit us at booth S36173 Performing complex measuring jobs at a glance. ZEISS Computed Tomography Trend Watch: What to Look for in Injecঞon Molding By Mahew H. Naitove Plascs Technology Trends to look for in injecঞon molding this year include enhancements to injecঞon mold speed and quality, process control and ad- vancements to the eliminaঞon of machine downঞme. Speed From all-electric presses, improved clamp and screw designs, new stack molds, faster pre- heaঞng of composite organosheets, and vari- otherm molding, look for exhibitors to demonstrate how they are tesঞng the limits of dry cycles. Injecঞon-machine designers are likely in- troducing all-electric presses that can com- pete with accumulator-assisted hydraulics in high-speed packaging and cap molding. Oth- er suppliers may showcase dedicated sys- tems for caps or PET preforms, using closer integraঞon of the machine and mold to over- lap moঞons and get the absolute most out of the cycle ঞme. Improved clamp designs as well as screw designs have also been appearing in the in- dustry's search for speed, along with tools like rotaঞng "cube" type stack molds that permit cooling to occur in one or two of the four faces. Faster preheaঞng of composite orga- nosheets is an emerging technology in spe- cialty molding for industries like automoঞve, Exhibitors showing off injecঞon molding equipment here at NPE, such as Milacron, pictured, are displaying enhanced speed, quality and process control. computers, and electronics. Rapid heat/cool, or variotherm, molding enhances both speed and part quality. Quality Recent developments in molding processing- control so[ware increase speed and quality as well, by automaঞcally adjusঞng injecঞon parameters for changes in material viscosity; finding the minimum necessary clamp force to avoid over-stressing parts and molds; and determining the appropriate coolant flow in mold circuits to achieve opঞmal heat removal without overdoing the cooling and wasঞng energy. In micromolding, special two-stage sys- tems featuring a fixed plasঞcaঞng screw and reciprocaঞng screw or plunger are designed for enhanced quality as well. These systems claim to eliminate the nonreturn valve so that shot size is volumetrically certain and repeatable. Process Control Look for new developments to be on display in injecঞon molding process control, specifi- cally focused on accurate monitoring and control of melt temperature in the barrel and of mold cooling in individual flow circuits. Eliminaঞon of Downঞme Machine builders always aspire to keeping machines running with the least possible downঞme, so look for advancements in re- mote service capability and predicঞve main- tenance. New approaches to "condiঞon monitoring" with on-machine sensors for vibraঞon, torque, temperature, and other variables are striving to all but eliminate un- planned downঞme. Ways are also being de- veloped to monitor the health of ballscrews, electrical systems, clamps, injecঞon units, and more, and to measure screw/barrel wear without pulling out the screw. Cra[ beer in barrier PET boles will be sold throughout the week of NPE2018 thanks to the efforts of exhibitor W. Amsler Equip- ment Inc. (Booth S21067). The beer will be sold in the Beer Garden, which is part of NPE's Bole Zone—an area consisঞng of 40 exhibitors who work in PET packaging. AMSLER EQUIPMENT, BOOTH S21067
