HYDRO-MECHANICAL DEEP-DRAWING

using the following processes:
- EHF: external high-pressure forming
- IHF: internal high-pressure forming

SAMPLE APPLICATIONS

  • Complicated geometries
  • Widened pipes
  • Intersections in the design
  • Parts with high surface quality
  • Parts consisting of multi-layer sheet metals
  • Prototype production
  • Small and medium-sized batch production

ADVANTAGES

  • Complicated geometries can be produced
  • High surface qualities
  • Lower tool costs compared with traditional methods
  • Drawing ratios of up to over 4.2 possible
  • Complicated parts in one drawing process
  • Little or no lubrication
  • No drawing beads and drawing traces
  • Source material for the deep-drawing parts can be coated, painted or polished

TOOL ADVANTAGES

  • Flexible range of use
  • Lower capital outlay costs
  • Rapid production times, as tools are not hardened
  • Due to coating of working surfaces, highly complex parts can be produced
  • Long service life of tools
