There are many parts of the car, and each part needs to be shaped through different processes for the assembly of the car. Some heat treatment options for automotive parts processing are more common than others, and this will vary depending on the industry and the particular type of system, machine, or equipment that will eventually be built with particular parts or components.

Annealing: Annealing is a carefully controlled heating and cooling process to change the microstructure of a metal and produce desired properties. Annealing is usually used to make the metal softer or to increase the ability to work with the metal. It can also be used to enhance the electrical conductivity of alloys.

Within the general category of annealing, normalization and stress relief are also popular and common heat treatment services in many industries and many different applications.

Induction hardening: The induction hardening process allows the surface of a part or a specific area of the entire part to undergo surface hardening to a very precise depth, which is ideal for parts where a very hard outer surface area is required to prevent wear.
