Annealing is a process where the parts are heated up and then they are cooled slowly to obtain a softer structure of the part and to optimize material structure for subsequent forming steps.

Parts that are annealed will have a change on the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. Also some magnetic properties may be changed by annealing the alloy in a controlled atmosphere.

The annealing is performed at high temperatures in a controlled atmosphere with an endothermic gas (Nitrogen) to avoid oxidation of the metal’s surface and scale. Parts may get a bright color with this process.

Benefits of this process are:

  • Superior quality with homogeneity on the parts
  • Reduction of heat treatment distortion and/or variation of distortion
  • Heating and cooling rates are adjustable
  • Green process, no emissions or need to dispose chemicals
  • Clean, non-toxic working conditions
  • Reproducible results
  • Clean and dry parts
  • State of the art, up to date technology
  • In accomplishment with CQI 9.

Some components that are annealed are solenoid housings, sensor cases, and a diverse variety of components that are made of steel, copper, aluminum, among others.
