atigue is a concern for heavy manufacturing companies, especially when running through processes that require workers to move hefty material to and from multiple stations manually.

At Production Fabricators Inc. (ProFab), each part took a total of two steps on two separate machines to complete. ProFab operators would bend large batches of steel blanks, first by pre-bending each blank on a press brake. The blanks were then formed again by inserting the pre-bent ends one at a time into a manual three-roll plate roll to complete the shaping process.

Using a SweBend QFV-1 vertical quick roll that was sourced through Trilogy Machinery (SweBend’s North American distributor), ProFab automated its bending process.

“The SweBend was an eye opener for us,” says Joe Hoofman, plant manager. “It was unlike any roller I had seen, which were horizontal rolls that you have to open the clamp and feed to extract the finished part.”

Trilogy approaches a customer’s specific situation by examining product mix and production volume factors. “If they are making entirely new or different products each day, they are probably a better fit for a traditional plate roll which has maximum flexibility,” Weeks says. However, if a customer produces repeat parts in large batches, a SweBend quick roll might be a better solution. “The quick roll machine will sacrifice some of the flexibility of a traditional plate roll in exchange for a massive reduction in cycle time and the elimination of the need for a highly skilled plate roll operator,” he explains.

In ProFab’s case, Trilogy identified a specific list of a dozen different parts produced in high volumes/batches. “We proposed the SweBend quick roll machine and once the machine was completed, we delivered a turnkey solution that required no on-site training and allowed the customer to simply power the machine up and start making good parts,” Weeks says.

SweBend QF roll systems are built to satisfy each customer’s specific set of circumstances; customers are increasingly interested in more automated processes.

“We can design and implement new or special features to suit specific needs,” Weeks says. “Features and options that benefit one customer may not benefit the next, so each project gets personal attention.”

Operator fatigue played a significant role in ProFab’s decision to invest in the SweBend. “We had one guy rolling these rings, hundreds per week,” Hoofman says. “These large rings are not easy to manually roll. He got it done but you could tell it physically wore on him. The SweBend machine was a godsend to our operators. They no longer need to load and off-load and that has helped tremendously.”

What began as a stamping house in the 1990s has evolved into an all-encompassing operation of laser cutting, forming and production work. ProFab offers processes including robotic and resistance welding. “We currently run four fiber optic lasers and eight press brakes along Wila USA new standard tooling,” Hoofman says.

Increased capacity allows ProFab to quote additional work it would not have had time for previously. “We can run through those high-volume jobs and when those are done, our operator can move on to other tasks,” Hoofman says.

ProFab was able to recuperate its capital investment in just over a year. After six years of continuously rolling parts for the trucking industry, the future looks bright. “We don’t see demand in that industry declining anytime soon. We’re keeping busy,” he adds.
