Based on the innovative hydroforming process, these machines assure outstanding profitability, exceptional operating flexibility and optimal productivity.
The machines allow manufacturing industrially metallic parts with hydroformed ends, such as fans, funnel-shaped pipes, special tips and end pieces, etc.
Before hydroforming, parts might be straight pipes, or parts already finished, for example, already bent or with fans and flanges or premounted clips, etc.
Socratech, an expert in the hydroforming field, has already developed a full range of hydroforming machines. We assure our customers a follow-up from development through manufacturing of typical parts to production runs on the machines.

THE HYDROFORMING TECHNIQUE

The hydroforming process uses the effect of high hydraulic pressure inside a tubular part to form at will and precisely according to an external die.
It offers many advantages compared to mechanical systems, which reduce a part's thickness by drawing or stretching it. The hydroformed thickness is more homogeneous, which allows reducing it (⇒ less weight, lower material cost, and for fans, greater flexibility). In addition, dimensional precision is clearly better.

OPERATING PRINCIPLE OF THE MACHINE

Application Examples
  • Hydraulic for forming and tightening the tools ;
  • Electric with numerically controlled axis for displacements and slaved operations.
  • According to the form to be obtained, the work may be executed either in a closed mould or in plates for the fan technique, or both may be combined.
  • In addition, the use of a hinged system allows significantly reducing forces and, therefore, investments.
  • During a cycle, it is possible to use two different hydroforming pressures. As a result, different forms may be made on the same part without requiring different hydraulic forces (such as a funnel-shaped part and waves).
