Triform Deep Draw Sheet Hydroform Press

Triform Deep Draw Sheet Hydroform Press


Triform’s deep draw sheet hydroforming presses use a state-of-the-art controls system in conjunction with a pressurized rubber diaphragm to form domes and hemispheres 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 and materials.

Innovative Sheet Hydroforming Machinery

The Triform line of Sheet Hydroforming Presses was developed in direct response to an unmet need in the marketplace for modern sheet hydroforming equipment.

At the time (2007), companies searching for sheet hydroforming presses were faced with equally unappealing options. Manufacturers of new sheet hydroforming equipment were extremely scarce, with new machine prices corresponding to the lack of competition. Those unable to afford new sheet hydroforming technology often resorted to sourcing used equipment which was manufactured from the 1950's - 1970's. These used machines presented several potential hazards including outdated hydraulic & control systems, a lack of available service & support and high transportation & intstallation costs.

Pryer, a leading provider of structural components, assemblies and kits to the aerospace industry, through their extensive utilization of sheet hydroforming equipment, understood clearly the hole which existed in the market. They began an exhaustive search to locate a machinery manufacturer with the experience & capabilities required to develop a modern answer to those aging machines manufactured decades ago.

This search led to Beckwood Press Company, a manufacturer of custom hydraulic presses & automation systems with nearly four decades of experience in product design, development and manufacturing, based in St. Louis, MO USA.

Beckwood leveraged its experience and in-house engineering & manufacturing resources - along with the sheet hydroforming process/application knowledge Pryer had amassed since its founding in 1965 - to create the first Triform in time for display at Fabtech 2008 in Las Vegas, Nevada. In the years since, numerous advanced Fluid Cell & Deep Draw Triform presses have been manufactured & delivered to facilities across the globe, including in Mexico, India, China, South Africa and the United States.

Today, Triform presses are sold, manufactured, serviced & supported by Beckwood Press Company, from their company headquarters in St. Louis, Missouri USA. With several additional Triform machines currently being manufactured for both new & repeat customers, it's clear that Triform's initial goal of filling a need within the marketplace has been successful. This broad acceptance, granted by the world forming community, has made Triform Sheet Hydroforming one of the truly great manufacturing success stories of the past decade.
