CrankPro™ Stationary Induction Heat Treating For Crankshafts - Inductotherm Group China

CrankPro™ Stationary Induction Heat Treating For Crankshafts

CrankPro™ Induction Heating Systems utilize patented SHarP-C™ (Stationary Hardening Process for Crankshafts) hardening technology, which eliminates work piece rotation during the induction heat treating process. This revolutionary approach enables faster part production while delivering superior hardness quality over other methods. There are several practical, economical and technical benefits associated with SHarP-C™  hardening technology including extended tooling life, dramatically reduced maintenance cost, simple operation, improved heat treating quality and dramatically reduced distortion.

Increased Production

  • Non-contact / Stationary Hardening Process
  • Only 1 moving part per station (Open/Close)
  • Increased throughput – Short heat times – less than 4 seconds
  • Production rates up to 90 parts/ hour

Improved Quality

  • Robust CNC machined inductors. No moving powered parts
  • Distortion is typically less than 25 microns, subsequent operations may be improved
  • Improved microstructure of hardened material

Reduced Downtime

  • Production ready “quick change” pallet assembly for fast coil changeover
  • Improved tooling life
  • Redundant duel bag quench filtration system, permits filter replacement while machine remains in operation
  • Modular design permits fast part changeovers

Reduced Operating Costs

  • Substantially reduced operating cost compared to rotational induction heat treating
  • Substantially reduced maintenance cost
  • 50% less energy consumption compared to rotational induction heat treating
