Our Sheet Metal Forming Expertise

Our expertise includes forming simulation using commercial finite element method (FEM) codes such as ABAQUS, Autoform, DEFORM, Dynaform, LS-DYNA, and PAM-STAMP. This significantly enhances our testing capabilities. We also specialize in assessments using ASTM, ISO standard formability tests such as uniaxial tensile tests, anisotropy value determination, limiting draw ratio (LDR), and forming limit diagrams (FLD). Below is a list of our technical expertise:

  • Material property characterization
  • Lubricant and coating evaluation
  • Forming process development
  • Formability evaluation
  • Forming process selection
  • Forming process modeling and simulation
  • Failure analysis (necking, thinning, springback, shear fracture, and edge cracking)
  • Forming of advanced high-strength steels (AHSS)
  • Hot forming of steel, titanium, and nickel alloys for automotive and aerospace parts
  • Warm forming of aluminum and magnesium alloys
  • Servo-press forming of steel and aluminum alloys
  • Stamping process and quality system assessment
  • Sheet metal forming technology training
