Fluid Cell sheet hydroforming presses are ideal for making parts with complex geometries, bends, and curves. During a fluid cell cycle, blank sheet material is placed atop a single stationary form block (tool), which rests unsecured on the lower platen or working surface. A pressurized diaphragm filled with hydraulic fluid extends over the tool and blank, expanding as it exerts equal pressure on every point inside the chamber. The result is a near-net-shape part which requires little or no secondary finishing.
Triform’s fluid cell sheet hydroforming presses come in a variety of sizes to accommodate parts ranging from 2″ to 120” long. Additionally, multiple parts can be formed in a single fluid cell cycle, as long as the tools and blanks fit within the forming area—including parts of different sizes.
Triform fluid cell presses are considered high-performance alternatives to traditional rubber pad forming presses. While pad forming typically applies pressure of ~1,000 – 1,500 PSI on the part, Triform sheet hydroforming presses offer 5,000 – 10,000 PSI. And, unlike traditional pad forming, which applies pressure only on the top surface of the part, Triform presses apply uniform pressure on every square inch of the part.
