Laser Case Hardening on Camshaft

Laser case hardening is a process that uses a laser to heat the surface of a metal part to a very high temperature in order to increase the hardness of the metal. This is a common process used on camshafts in engines because they are subjected to a lot of stress and friction.

The process of laser case hardening first requires creating a mold of the camshaft. This mold is used to create a replica of the camshaft that will be hardened. The replica camshaft is then heated to a very high temperature in a laser. The heat from the laser causes the metal to become extremely hard.
