The Triform Process
Based on the same concept as the hydroforming machines of the past, Triform presses use high-pressure hydraulic fluid in a flexible rubber bladder or diaphragm to shape sheet metal against a single tool. The process can create a wide range of geometric shapes, either shallow or deep drawn, from most metals, even high-strength stainless steels.
A Triform press can replace many different metal forming processes, and can consolidate multiple steps into a single operation. Most parts, including those which are deep drawn, are finished in one cycle and require no additional finishing work, aside from a possible trim.
Triform presses flow the material during the drawing process rather than stretching it, resulting in minimal material thinning and uniform wall thicknesses.
