RETHINK FILTRATION NO MOVING PARTS. NO HYDRAULICS. NO LEAKS. • Saves labor & downtime. No hot breaker plates or dirty screen packs to change • 120' roll of filter screen lasts many months in 24/7 operation • Unconditional 10 year guarantee not to leak The Leader in Continuous Melt Filtration Since 1969 HITECH ™ fully automatic, continuous screen changers deliver a high level of process integration with a small footprint. • Screen automatically advances to maintain constant differential pressure across the screen • Consistent process pressure and melt temperature result in closer tolerances, uniform gauge control, superior product quality Visit Us at Booth# W4553 MES System Adds Mobile Reporting & Maintenance Apps Arburg's November user group meeting focused on the company's ALS host-computer system at Arburg's Lossburg, Germany, head- quarters. The meeting presented new functions to make data from this MES (manufacturing execu- tion system) accessible on mobile devices. T hese included the new ALS Mobile front end with a respon- sive design, as well as the Mobile Reporting report client and the new Mobile Maintenance module, which makes it possible to execute, acknowledge, and comment on maintenance orders via mobile devices. Arburg's U.S. office is in Rocky Hill, Conn. 860-667-6500 • arburg.com INJECTION MOLDING INJECTION MOLDING Fine-Tuned Control for Hot-Runner Valve-Gates Synventive Molding Solutions, Peabody, Mass., has introduced synflow3 technology, which allows molders to slow the opening of the hot-runner valve pin for a set distance and hold at that position until closing, or alternate different moves within a cycle. The updated pin control can stop the pin and hold it at any position mid-stroke. Used to help eliminate cosmetic defects on sequentially filled parts that are caused by sudden flow-front accelerations and hesitations when the delayed pins open, synflow3 allows for individual flow-rate control of each nozzle to balance family molds or fill complex multi-gated geometries. In addition, alternating opening profiles can be programmed for ability to pre-fill cold runners or create differential packing within complex multi-gated parts. No connection to the injection machine is necessary. Synventive reports that the most significant difference between synflow and other pin control technologies is the ability to apply it to existing tools. For example, if during mold sampling, it's determined that synflow could improve the process, Synven- tive says the technology could be installed and running in minutes. Synventive notes that its valve-gated hot runners come standard with SVG+, which includes position sensors. Synflow can be added to any activeGate-enabled system through external hookups. This means that molders no longer need to commit to these flow-control tech- nologies for the life of the tool, not knowing if they will ever actually be needed. 800-367-5662 • synventive.com 70 JANUARY 2018 Plastics Technology PTonline.com Keeping Up W it h Technolog y
