Induction hardening machines-Automotive-

Crankshaft

Crankshaft
  • Semi-open coil tracks rotating part, minimizing warpage.
  • Hardens pins as narrow as 10.5mm using thin coil and transformer designs.
  • Power reduction method adjusts power as the part rotates to achieves even case depth.
  • Coil-part positioning trend and total energy monitoring systems for hardening control.
  • Compact design 1/3 of original volume and height under 2m for easier shipping, installation

Camshaft

Camshaft
  • Coil moves eccentrically to track rotating cam.
  • Achieves even casing and prevents nose cracking caused by overheating and post-process grinding.
  • Automatic adjustment of coil position and parameters for each cam possible.
  • Original concentrator ring prevents unnecessary heating of camshaft journals to ensure low warpage.
  • Coil designed to match cam width to prevent drastic difference in temperature on the cam surface. Built without cores for long coil life.

Driveshaft

Driveshaft
  • Semi-open coil built to the shape of the part generates axial current for even case depth.
  • Original line coil one-shot hardening achieves even hardening without warpage.
  • Energy consumption reduced 50% compared to scan hardening.

Constant Velocity Joint

Constant Velocity Joint
  • Converter with 3 frequency settings for hardening ball grooves, axle, and spline.
  • Multi-turn coil achieves stable reheating.
  • Air pockets in grooves minimized during quenching to prevent soft zones.
  • Concentrator ring prevents overheating of edges and diagonal groove plunger.

Shaft Gear

Shaft Gear
  • Semi-open line coil one-shot hardening treats two parts simultaneously.
  • Shorter cycle time than traditional method while preventing overheating.

Gear Contour Hardening

Gear Contour Hardening
  • Precise temperate control minimizes deformation during heating and quenching.
    Achieves ideal casing along the gear contour even for gears with small modules.

Pinion Gear

Pinion Gear
  • IH hardening energy consumption 80% less than carburizing.
  • Warpage minimized by pinpoint hardening.
  • Automation possible for high productivity.
