Tube Hydroforming Technology(THF)

Benefits of Hydroforming Tube vs. Traditional Manufacturing

Traditional Manufacturing Hydroforming

  • Multiple pieces to be welded together
  • Multiple dies are needed
  • Weld strength/rigidity are concerns
  • Roughly 10% scrap metal created
  • High cycle time

  • One piece raw material (tube)
  • One hydroforming die
  • No welded seam, increased strength
  • Almost no scrap metal (~1%)
  • Low cycle time

Benefits of Hydroforming Tube vs. Traditional Manufacturing

Part and Assembly Design
  • Shape of cross section:Stiffness demands
  • Part core line:Requests of hard points in assembly
  • Proposals of assembly design
Function Analysis

Static loading

  • Stress analysis-increased the strength of hydroforming part, and decreased the stress
  • Displacement analysis-hydroforming part is stronger than the stamping.

Static twisting

  • Fatigue analysis-confirmed the fatigue resisting ability of hydroforming part as requested.
  • Stiffness analysis-confirmed the stiffness of assembly as requested.

Dynamic crashing

  • Bucking analysis-analysis of demanded buckling mode and confirmed the buckling of hydroforming part as required.

Dynamic and static twisting

  • Stress analysis-confirmed the strength of hydroforming part as requested.

 

 

 

  • Advanced confirmation of hydroforming feasibility
  • Confirmed the part manufacturing processes
  • Die structure analysis
  • Die closing force analysis
  • Laser cutting path programming
