Industrial IH Equipment

Hardening Technologies for Machine Tools, Industrial Machinery, Robotics

Our hardening technologies ensure precise, efficient, and automated treatment. Advanced coil designs, cooling, and high-speed methods minimize warpage and maintain accuracy. Automation systems provide consistent results, while specialized techniques prevent cracking in complex parts. High-frequency induction also offers a fast, precise alternative to carburizing for small-lot workpieces.

Semi-Open Coil for Case Depth in Wide Grooves

  • Axial current ensures sufficient case depth, even in wide grooves.
  • Core-less design prevents quality issues from core deterioration.

Even Cooling Combination Mechanism

  • Provides uniform cooling after heating.
  • Achieves high-precision lead pitch and minimal warpage.
  • Intensively cools groove area, then entire workpiece for stable hardening.

Original High-Precision Output Mechanism

  • Matching unit moves horizontally at high speed while maintaining stable output.
  • Eliminates need to move the workpiece.
  • Allows for more compact equipment design.

Guide Rails

Original Fixed Coil-Gap Mechanism

  • Ensures even heating of only necessary areas.
  • Maintains fixed coil-gap between coil and hardening surface.
