Extrusion International 2-2018

PREVIEW 50 Extrusion International 2/2018 W. Amsler Equipment Inc. www.amslerequipment.net Booth S21067 W. Amsler Equipment, a leading supplier of all-elec- tric linear PET stretch blow molders, will introduce its next-generation four-cavity all-electric reheat stretch blow molder at the upcom- ing NPE2018. The company will also exhibit its newly- enhanced leak tester that inspects bottles from 10ml to 23 liters and its stand- alone spin trimmer for both stretch- and extrusion-blown containers. The L42X all-electric reheat machine offers several new features including preferential heating, neck ori- entation, and hot-fill capabilities. “For custom blow molders, the next-generation four-cavity machine provides versatility to enable PET bottle production in a range of configurations and siz- es,” said Heidi Amsler, sales and marketing man- ager for W. Amsler. The new machine makes up to 2-liter containers at a rate of 6500/hour in four cavities. It can also be used to run two-cavity molds for production of larger containers up to 5 liters. Neck finishes range from 18mm to 70mm. The L42X reheat machine has four parallel heat- ing ovens, one for each cavity. It comes equipped with 12 Bosch-Rexroth servo motors, compared to three servos for the previous model. The extra servos provide more repeatability, lower energy consumption, and require less wiring, resulting in easier troubleshooting, according to W. Amsler. The machine also has a 40-ton servo-driven mold clamping system. Servo systems are used to con- trol preform loading, preform transportation through the machine, rotation through the ov- ens, stretch rod actuation, motion towards the molding station and clamp opening, closing, and bottle unloading. Other key features include agitated preform in- feed to prevent bridging, preform temperature sensing prior to blow, pre-blow flow control for each cavity, water-cooled neck shields, and a large touchscreen operator interface. Servo-driv- en stretch rods are 14mm with 10mm and 12mm options. The L42X comes equipped with a large touch- screen operator panel from Wonderware. It has a Windows-based human machine interface (HMI) with full access to assembly drawings, bills of ma- terials (BOMs), set-up guides, troubleshooting, and training videos. The four-cavity system is commercial and W. Amsler has already sold a machine to a custom blow molder. Next-Generation Four-Cavity Stretch Blow Machine
