Deep Draw Hydroforming

For applications requiring a controlled flow of the material, such as deep drawn parts or those with curved geometries which have the potential to wrinkle during the forming process, Triform Deep Draw presses are the ideal solution.


In the computer-controlled Deep Draw process, the downward-acting bladder primarily acts to hold the material during pressurization, as the tool is extended atop a hydraulic punch cylinder. This draws the material into the bladder and allows it to flow as needed.  


Both the bladder pressure and punch position are tightly controlled (down to 1% of full scale and +/-0.002″ respectively) using Triform’s advanced controls and hydraulics system. Through the multi-level recipe program (up to 30 steps), operators can make fast, accurate adjustments, greatly improving and accelerating the part development process.  


Triform’s proprietary”In-Sight” feature allows for visual inspection of the partially-formed part, mid-cycle, with the ability to abort or continue the cycle after inspection. This unique feature greatly facilitates new part development, decreasing scrap rates and the time to first article.

Fluid Cell sheet hydroforming create parts with a single unmated tool, using downward force of a pressurized bladder, or diaphragm. The blank, is placed atop a stationary form block, which rests unsecured on the lower platen or working surface. The diaphragm is then pressurized with hydraulic fluid, expanding as it exerts equal pressure on every point inside the chamber. Multiple parts can be run 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 can be thought of as high-performance alternatives to traditional solid-block rubber pad forming. Pad forming typically applies pressure of ~1,000 – 1,500 PSI on the part, Triform sheet hydroforming presses offer 5,000 – 10,000 PSI on the part. Unlike pad forming, which varies pressure across the part, Triform presses place uniform pressure on every square inch of the part’s surface. The result is reduced material wrinkling, increased definition, often eliminates the need for manual hand-finishing.
