Supplier's Category: All Hydroforming: Shaping metal sheet or tube using high-pressure fluid

Hydroforming shapes metal sheet or tube using high-pressure fluid pressed against a die, forming complex curved geometries in a single operation that would otherwise need multiple stamping steps. It’s especially suited to smooth, structurally efficient shapes with fewer weld joints than a stamped-and-welded assembly.

Hydroforming’s main advantage — complex curved shapes with fewer joints — matters most in weight- and strength-sensitive applications.

  • Automotive: structural frame rails, exhaust components, body panels
  • Aerospace: lightweight structural tubing and ducting
  • Bicycle and sporting goods: seamless tapered tube shapes

What to check before tooling a hydroformed part

Wall thinning at high-deformation areas is the main risk in hydroforming, and not every shop simulates it before cutting steel.

What to ask

  • Do they run forming simulation to predict wall thinning before tooling
  • What press tonnage and pressure range do they have, relative to your part size
  • What’s their experience with your specific alloy’s formability
