Industrial Oven | Annealing Oven

Annealing Oven

Annealing is a heat treatment process which alters the microstructure of a material to change its mechanical or electrical properties. Typically, in steels, annealing is used to reduce hardness, increase ductility and help eliminate internal stresses. Annealing ovens are used to heat treat the materials in a controlled and consistent environment.

Annealing can be completed in a batch or a conveyor oven. For higher temperatures, ITS also manufactures annealing furnaces. Contact our team for more information.

Annealing Ovens will eliminate internal stresses in materials such as glass, various alloys, and polymer.

The function of an Annealing Oven is to perform the process of softening an object or changing other properties of the object through cycles of heating and cooling. The Annealing Oven can be configured in various chamber styles such as Batch or Continuous Conveyor. Typical Annealing applications will soften, enhance ductility, and cold working properties in various materials. These materials include aluminum, brass, copper, steel, various alloys and polymer.

Each Industrial Oven project undergoes a comprehensive evaluation of every production requirement. The assessment includes areas such as production goals, part configuration and construction, part mass, temperature profile, and facility location or elevation.

Industrial Batch Oven


Annealing Oven Features include:

  • Economical operation is achieved with superior thermal process engineering practices that apply state-of-the-art insulation material, airflow management, and custom programming.
  • Recirculation fans with high efficiency motors to reduce energy consumption.
  • Recirculation ductwork designs provide precise airflow to specific areas of the product resulting in smaller foot print ovens thus reducing utility and factory space costs.
