Triform’s deep draw sheet hydroforming presses use a state-of-the-art controls system in conjunction with a pressurized rubber diaphragm to form complex geometries up to 12” deep in a single cycle. As pressure is applied, the tool is extended on a hydraulic cylinder, drawing the material into the diaphragm. Cans, boxes, or parts with curved flanges, which have a tendency to wrinkle, also benefit greatly from Triform’s controlled flow of material.

Since the diaphragm acts as a universal female die, mated tooling is not required. This can reduce tooling costs by 50% -90% compared with conventional press tooling! Additionally, tools can be made from a variety of materials including steel, aluminum, 3D printed substrates, epoxies, and even wood.

Bladder pressure and punch position can be tightly controlled (to 1% of full scale and +/-0.002” respectively), and Triform’s ‘In-Sight’ feature allows you to pause the cycle at any point in the forming to inspect the results. Depending on those results, you can continue the cycle or abort it to modify the recipe. This ability to look inside the chamber during formation greatly expedites new part development, saving valuable time & materials.
