What is Sheet Hydroforming?
Sheet Hydroforming is a metal forming process that uses pressurized hydraulic fluid in a flexible diaphragm to shape sheet metal against a single, un-mated tool. The process can create a wide range of complex geometric shapes from a variety of materials including aluminum, steel, stainless, titanium, niobium, Inconel, copper, composites, and more. Sheet hydroforming presses can combine or even replace different metal forming processes including press brake forming, traditional draw forming, rubber pad forming, progressive die forming, and more. These machines can also consolidate multiple steps into a single cycle, virtually eliminating secondary finishing processes such as polishing, annealing, or welding.
Types of Sheet Hydroforming
The two primary types of sheet hydroforming presses are fluid cell and deep draw. Fluid cell sheet hydroforming presses create shallow parts with open corners while deep draw sheet hydroforming is used for taller parts with closed corners and parts up to 15-inches tall.
