Extrusion blow molding unit is Hesta's largest

Issue: April 2018

Hesta900 Hesta’s new extrusion blow molding machine can accommodate molds up to 34.6 inches wide and 15.7 inches long. It features the company’s HES system, which adjusts for different mold thicknesses and enables users to set clamping forces at any level from 0 to 100 percent of maximum force. It can make containers with capacities of up to 5 liters. Hesta’s distributor in the U.S. is Jackson Machinery.

What’s new? The size. With a 35.4-inch linear stroke and about 45 tons of clamping force, the Hesta900 is Hesta’s largest-ever all-electric machine. At NPE2018, Hesta will use the machine to make eight 1-gallon PET containers at a time in a four-plus-four-cavity configuration.

Benefits Energy efficiency, ease of use and a small footprint. Compared to hydraulic machines, the Hesta900 uses less than half as much energy. Its HES system not only saves energy, but minimizes wear on parts, such as molds, motors, blow pins and cutting rings. Also, because it automatically adjusts clamping force, the machine produces quality parts with little flash. Additional operator-friendly features include a design that allows for molds to be swapped out in just 20 minutes. Though more powerful than the Hesta700, the second-largest machine in Hesta’s portfolio, the Hesta900 is only about 4 feet wider.
