W. Amsler Equipment Inc. will introduce its next-generation four-cavity all-electric reheat stretch blow molder at the upcoming NPE2018 May 7-11 at the Orlando Country Convention Center in Orlando, Fla. (Booth #S21067). The company will also exhibit its newly-enhanced leak tester that inspects bottles from 10ml to 23 liters and its standalone spin trimmer for both stretch- and extrusion-blown containers.


W. Amsler Equipment Inc. will display its four-cavity stretch blow molding machine with a larger touch screen control.

New L42X All-Electric Reheat Machine

The L42X all-electric reheat machine offers several new features including preferential heating, neck orientation, and hot-fill capabilities.

Heidi Amsler, sales and marketing manager for W. Amsler, said:
“For custom blow molders, the next-generation four-cavity machine provides versatility to enable PET bottle production in a range of configurations and sizes.”

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.

Key Features of L42X Reheat Machine

  • 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.

Other Key Features

Other key features include agitated preform infeed 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-driven stretch rods are 14mm with 10mm and 12mm options.

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.

The four-cavity system is commercial and W. Amsler has already sold a machine to a custom blow molder.
