CHICAGO—Automa North America of Dublin, Ohio, featured injection stretch and accumulator head blow molding equipment at NPE 1997, held June 16-20 in Chicago.
Parent company Automa SpA completed its NSB 50 unit just before the show. The machine produces wide-mouth clear PET containers at a rate of 1,200 per hour.
The machine has three stations: preform injection, thermal conditioning and stretch blow and discharge.
Automa boasts that the NSB 50 is inexpensive, compact and consumes little energy. It operates with a Moog global controller on a closed-loop system. With a changeover time of four to six hours, the machine can be run for small-volume orders.
The AE-30 machine, an accumulator head model, will be available in the United States this fall. AE-30 can be equipped with single or dual heads with the ability to operate as a continuous molding machine. It produces 30- to 50-liter containers.
The compact machine accommodates accumulator heads with 10-18 pounds of capacity.
The platens are mounted on tie bars located between two machined side frames. Two hydraulic cylinders mounted in the center of the platens and at the midpoint between the tie bars apply the closing force. The extruder assembly is attached to a machine frame with longitudinal and vertical adjustment and can be rotated from a fulcrum beneath the gear motor for easy mold changes. All extruder motions are controlled by gear motors.
