BLOW MOLDING INJECTION MOLDING 'Individual Mold Control' for PET Reheat Stretch-Blow Machines Agr International, Inc., Butler, Pa., a specialist in quality- monitoring and process-control systems for PET stretch-blow molding (agrintl.com), has teamed up with KHS, a major supplier of reheat stretch-blow machines (U.S. office in Waukesha, Wis.; khs.com), to add another level of control for PET bottle making. The two firms worked to enhance Agr's Process Pilot controls with new Individual Mold Control for KHS Series IV and V machines. Monitoring the performance of individual molds through the Process Pilot system can quickly identify and correct issues at individual mold stations and captures valuable mold performance data that can help deter- mine the optimal time for system maintenance. Agr's Process Pilot system works with the blow molding machine to proactively manage and maintain container material distribution at a specified thickness within around 0.01 mm. This is accomplished by continuously monitoring each bottle for material distribution, analyzing minute changes, and adjusting the machine controls accordingly. Individual Mold Control takes this to the next level by eliminating mold-to-mold variability that is common in PET bottle production. www.MarukaUsa.com Maruka's expertise can help you decide Electric or Hydraulic TOYO Si-6 Series All-Electrics 33% faster cycle time in less space, high-speed resin changes, power meter, 10x faster controller, multi- material-ready and 100% made in Japan to ensure highest quality standards. 20-1500 tons.

See us at Booth #W911 during NPE 2018 in Orlando, May 7-11 New eLearning Course on 'Math for Molders' RJG Inc., Traverse City, Mich., has intro- duced its first eLearning course, "Math for Molders." It develops foundational math skills needed in the field and for more advanced RJG courses. The online course allows students to complete each module at their own pace, including the option to replay sections as needed. It takes an average of 9-10 hr to complete. There are eight units in the course, each with multiple interactive modules that include videos, animations, and practice activities. Using real scenarios, molders will be better prepared to calculate data, enabling them to match mold requirements with appropriate machines and avoid common defects while preventing machine and mold damage. Some course highlights include calcu- lating areas of various shapes and total projected area at the parting line; ratios used in screw design and hydraulic inten- sification ratios; and volumetric shot size and barrel capacity. 231-947-3111 • rjginc.com @plastechmag 73 Plastics Technology N E W P R O D U C T S F O R P L A S T I C S P R O C E S S I N G
