W. Amsler Equipment Inc., Canadian supplier of all-electric linear PET stretch blow molders, will introduce its next-generation four-cavity all-electric reheat stretch blow molder at the upcoming NPE 2018.
The L42X all-electric reheat machine offers several new features including preferential heating, neck orientation, 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 sizes, according to the manufacturer.
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 18 mm to 70 mm. The L42X reheat machine has four parallel heating 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 control preform loading, preform transportation through the machine, rotation through the ovens, stretch rod actuation, motion towards the molding station and clamp opening, closing, and bottle unloading.
The L42X comes equipped with a large touchscreen operator panel from Wonderware. It has a Windows-based human machine interface (HMI) with full access to assembly drawings, bills of materials (BOMs), set-up guides, troubleshooting, and training videos.
