Shaping general low-volume manufacturing with Flexform

The Flexform technology provides solutions for appliance and white goods manufacturers, and for a wide variety of low-volume custom parts fabricators.

Flexform is a modern sheet metal forming method for cost effective low-volume production. Quintus Technologies has supplied high-pressure rubber diaphragm presses to the world’s major manufacturers for decades. Flexform is used by manufacturing companies for general low-volume sheet metal forming to achieve low-cost, high quality parts with short lead times.

Flexform is ideal for:
  • Prototype and development components, from small shallow parts to large deep parts, in all alloys.
  • Low-volume production items, from small shallow parts to large deep parts, including trimming, in all alloys.

Shaping the Low Volume Sheet Metal Forming Industry with Flexform™ Presses

In Flexform, sheet metal is formed of rigid, shape-defining tool half by a flexible rubber diaphragm supported by high hydraulic pressure.

User benefits

Prototype and development components:
Flexform results in high quality, low-cost parts with short lead times.

  • forming with one rigid low cost tool half and a flexible rubber diaphragm
  • high, uniform forming pressure for parts with close tolerances
  • easy tool modifications and no matching of tool halves

Low-volume production items:
Flexform results in high quality, low-cost parts with short lead times.

  • forming with one rigid low-cost tool half and a flexible rubber diaphragm
  • forming including undercuts, flanging and trimming with a single tool half
  • easy tool modifications and no matching of tool halves
  • prototype tool can also be used for production

Flexform examples

Electrolux stove top

Electrolux stove top in 1.5 mm (0.06 in) mild steel preformed in a plastic die and formed to final shape on an aluminum punch tool with inserts to 800 bar (11,600 psi).

Autoclave end plate

Autoclave end plate in 8 mm (0.31 in) stainless steel formed in an aluminum die in one operation to 2,000 bar (29,000 psi). A hardwood die was also used for test purposes.

Deep Draw example

Duct. A steel tube

Duct. A steel tube is placed in the tool with a circular rubber insert in the center. The pressure from the Flexform diaphragm, assisted by the rubber insert, then expands the metal into the die.

Learn how we can help you increase productivity and lower production costs

We can control the pressure more accurately on small parts in this press and eliminate even more touch labor. The press is easy to operate, user friendly, requires short time to train operators, and needs little maintenance.
Reference | Cessna Aircraft Company Four decades of high-pressure parts forming
For many parts, hand correction of incompletely-formed shapes has been completely eliminated. We have documented cost savings of 25 to 42 percent on sampled parts due to fewer required cycles and reduced manual rework.
Reference | Daher Daher cuts costs with high-pressure parts forming
The quality of the parts meets the same standards set by the original press, but setup time has been reduced remarkably: 2.5 minutes less per part. Overall labor time has been cut by 60 percent, from 9 minutes to 3.6 minutes.
