Sheet metal forming automotive industry with Flexform™

For decades, Quintus Technologies has supplied Flexform solutions to major automotive manufacturers worldwide, including Ford, Daimler-Benz, Volvo, BMW, Rover, GAZ, and Saab.

As with the aerospace industry, Flexform is used widely by automotive manufacturers for fast, low-cost prototyping, validating tools and parts, and saving valuable time in the new model development process.

Automotive metal pressing

And although auto making typically involves high volumes, there are segments of the industry where Flexform is the preferred method for production parts. These include limited edition specialty cars, buses, trucks, commercial vehicles, and farm/construction equipment.

Formed components include fenders, doors, hoods, roof and floor panels, pillars, support beams, and similar items. Flexform is considered economically viable for parts with production volumes up to some thousands of parts per year.

Innovative Metal Forming Technique could Have a Significant Impact on Press Shops of the Future

From Aero to Auto
“One of the most flexible forming processes in the automotive industry, in the most literal sense of the term, is the Flexform technology from Swedish company Quintus Technologies, based in Västerås, around 100km west of the capital Stockholm. Instead of shaping sheet metal between two heavy machined steel dies, only one such hard die surface is employed with the other being replaced by a rubber diaphragm, which is then forced against the surface of the blank by hydraulic pressure.”

The right press for your business

QFC 0.7 x 1.8 - 800 sheet metal forming presses

Fluid Cell Presses

Rectangular Trays

Quintus offers a full line of standard models of Flexform™ Presses with rectangular trays dimensions up to 1.8 x 3.6 m (71 x 142 in) and pressures from 800 bar (11,600 psi) to 1,400 bar (20,000 psi). The cycle time is normally one to three minutes, depending on press size, formed parts and selected pressure.

Fluid Cell Presses

Circular Trays

QFL presses are compact units with circular trays, designed for faster forming of smaller parts.
Cycles average about one minute, with maximum pressure of 800 bar (11,600 psi). These presses are commonly used for off-loading and back-up for larger rectangular tray presses and for rapid forming of smaller parts.

Modern Quintus Fluid Cell Deep Draw Press

Fluid Cell Presses

Deep Draw Presses

Quintus offers a line of standard deep-draw press models with forming area/diameter ranging from 560 mm / 22 inch to 1100 mm / 43.3 inch. Pressure ranges from 800 bar / 11,600 psi to 1,200 bar / 17,400 psi. The cycle time is depending on the tool size and the pressure level required, but normally range from some 30 seconds to two minutes.

Quintus Technologies Flexcell Concept

Fluid Cell Presses

Flexcell™ Concept

The Flexcell™ concept minimizes the time for tooling changes and takes the time for new tool set-ups from hours to seconds. The concept substantially increases productivity, allowing fabrication of small production batches, when a wide variety of part shapes are required. The Flexcell™ concept also makes the handling of heavy tools easier, while taking away the manual feeding of parts, making this process safer and more efficient.

Benefits and Applications for the Automotive Industry

Automotive front fender part created on a Quintus metal forming press

Front fender

Front fender in 0.8 mm (0.03 in) mild steel formed in three steps over a Kirksite punch with fixed blank holder: (1) preforming with blank holding for stretching, intermediate trimming, (2) preforming, removal of filler pieces, and (3) final forming, including an undercut in the top area, to 800 bar (11,600 psi).

Automotive Front reinforcement part created on Quintus hydroforming press

Front reinforcement

Front reinforcement part in 1.5 mm (0.06 in) mild steel formed in two steps over a Kirksite punch with fixed blank holder: (1) preforming, intermediate trimming, removal of filler pieces and (2) final forming to 1,400 bar (20,000 psi).

BMW shock part created on Quintus Technologies Flexform hydroforming Press

BMW shock absorber

BMW shock absorber support in 2 mm (0.08 in) mild steel deep drawn with a movable punch and blank holder in one step to 1,000 bar (14,500 psi). The part has also been formed in aluminum alloy. The punch was made of a low melting zinc alloy and the blank holder of steel.
