inigence Springback Compensationfor highest part quality

By a reasonable combination of experience and innovation we provide our customers with compensated 3D-CAD-tool data which convince through updateability as well as dimensional and class-A surface quality.

Springback Management: dimensional accuracy in sheet metal forming

The accurate production of complex car body components due to elastic springback still represents a great challenge. We meet this with our self-developed compensation software.

Essential software components of the inigence compensation tool:

  • discrete scaling of the drawing tool based on the calculated stress distribution
  • standardized compensation strategy – basically useable for all sheet metal parts and materials
  • physical compensation algorithm

Benefits of the inigence springback compensation:

  • equal in length compensation of springback
  • stable part location in all tools along the process sequence
  • avoidance of unintended (local) deformations in subsequent operations after drawing
  • update capability of the compensated CAD model
    and thus
  • robust dimensional accuracy
  • class-A surface quality
  • automated processing of geometrical changes

Our services

  • FEM process simulation of the entire manufacturing process with a focus on springback
  • analysis of the springback behaviour and process robustness
  • discrete scaling of the drawshell 
  • creation of the compensated tool surfaces
  • validation of the compensated manufacturing process by FEM process simulation
  • creation of a compensated and update capable 3D-CAD-process plan
