Triform to manufacture fluid cell sheet hydroforming press for H&R Parts

Beckwood Press Co., a St. Louis-based manufacturer of custom hydraulic presses and automation systems, has been awarded a contract by H&R Parts Co. to manufacture a Triform model 24-5BD fluid cell sheet hydroforming press. With a 24-in.-dia. forming area and 5,000 PSI, the press will support H&R’s aluminum aerospace part production.

During the fluid cell process, a pressurized rubber diaphragm filled with hydraulic oil shapes sheet material against a single tool. This evenly distributed pressure results in net-shape part production. The Triform diaphragm conforms to any shape within the forming chamber, so there is no need for mated male/female dies. Multiple parts can be formed in a single cycle, as long as the tools and blanks fit within the forming area.

Using a stationary blank holder in conjunction with a single tool, H&R will be able to form parts with closed corners and severe curves in 20 seconds or less without the need for secondary hand finishing, the company states.
