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 sheet hydroforming presses are revolutionary. Since the 1980’s there has been a clear and recognized need for an alternative solution to the older style fluid cell presses. By utilizing the latest computerized engineering software, modern hydraulics and advanced CNC controls, Triform now provides affordable hydroforming presses that are essential for manufacturers involved in sheet metal forming.
Triform offers a unique design and several distinct advantages:
· Low Tooling Costs (single tool technology)
· Net Shape Part Production
· Minimal Part Thinning
· Minimal Spring Back |
· Ideal For High Strength Materials
· Ability to Draw Complex Parts in One Cycle
· Minimal Work Hardening
· Minimal Distortion Of Sheet Surface Finish |
|
Ideal alternatives to traditional pad forming, Fluid Cell models use the downward pressure of the bladder to form the material around an unsecured tool placed on the flat surface of the lower plate.

For deep drawn parts or those with complex curved geometries, our Deep Draw models use
a punch cylinder (on which the tooling is attached) that extends upward during the bladder pressurization to draw the material into the bladder and form the part.
