Camshaft Hardening

Induction hardening offers several advantages when applied to camshafts in the automotive industry.

Benefits:

  • Wear Resistance: Induction hardening significantly increases the wear resistance of the camshaft surface. This is crucial because camshafts experience high tensile and torsion stresses during operation due to their length and peripheral speed. A hardened surface helps minimize wear and prolong the component’s life.
  • Controllability and Repeatability: Induction heating allows each camshaft to be hardened with precision when integrated into production lines. The heat parameters can be fully adjusted, ensuring consistent results and repeatability.
  • Preservation of Core Properties: During induction hardening, the core of the camshaft remains unaffected by the heat. This preservation of the core’s softness ensures that the camshaft retains its tensile strength and torsion resistance.
  • Reduced Maintenance Costs: Induction-hardened camshafts experience less wear, leading to reduced maintenance and replacement costs.
  • Improved Part Quality: The controlled and precise heating process results in a uniform hardness pattern across the camshaft surface, enhancing overall part quality.
  • Space Savings: Induction hardening equipment has a small footprint, making it space-efficient for manufacturing facilities.

Induction hardening provides a cost-effective, precise, and reliable method for enhancing the performance and durability of camshafts in automotive engines.
