Düsseldorf, Germany — With 80 percent of its injection blow molding machines sold overseas, U.S.-based Jomar Corp. (Hall 14/A32) had a lot of customer requests to reduce energy consumption.
Company officials turned to Charlotte, N.C.-based Bosch Rexroth Group at NPE 2015 in Orlando, Fla., with the challenge and a tight timeline. Nineteen months later, the result of this collaboration is a custom-designed, servo-driven hydraulic system to power Jomar's new machine and its plastifier.
“The way we did the plastifier is unique to the industry,” Thomas Aufiero, a regional sales engineer for Bosch, said of the Jomar IntelliDrive it is showing at K 2016. “A vertical plastifier requires more torque, but all-electric is very expensive. We could do it with standard hydraulic motor components, except we're unique with a new radial-piston type motor to generate the torque required without any special gear box or anything else.”
Now the replacement cost of that motor is a fraction of an electric drive, while the energy savings is close to, if not better, Aufiero said.
The machine uses 40 to 50 percent less energy and it has more speed, added Ron Gabriele, Jomar sales manager.
“It's actually faster than our other machine,” he said. “It's dry-cycle time went from 2.4 seconds to 1.8 seconds so it's about a half-second faster. When you're making millions of bottles per year it's a big difference.”
Jomar's customers make bottles for products sold by Avon, Gerber's, Procter & Gamble and Unilever. The client list includes Düsseldorf-based Gerresheimer AG, which already purchased the model on display at K 2016.
“They're always talking about sustainability,” Gabriele said. “That's one of their tenets. They sent a technician out to review the machine and he loved it. He's their ace Jomar guy with 28 years of experience so he knows the machine as well as we do. That was a huge moment of validation.”
