Based on the innovative hydroforming process, these machines assure outstanding profitability, exceptional operating flexibility and optimal productivity.
They allow manufacturing industrially hydroformed metallic parts such as metallic fans, compensators, parts with reduction or expansions, 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 TECHNIQUEE

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

Exemples d'application
  • Hydraulic for the parts forming and tools tightening,
  • Electric with CNC axis for the displacements and the servo-controls.
  • 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).
