CODERE SA, based in Switzerland, designs and manufactures modular industrial furnaces for the heat treatment of ferrous and precious metals.

Choose from multi-treatment batch lines, continuous belt and vacuum furnaces, precious-metals equipments, and peripheral solutions for washing and quenching—engineered for reliability, efficiency and full process control, tailored to demanding industries worldwide.

The aerospace industry imposes some of the strictest metallurgical and process requirements in the world.

Components used in flight-critical assemblies must combine high mechanical strength, dimensional stability, and absolute reliability — all while complying with international standards such as AMS 2750 and NADCAP.

With more than 35 years of experience, Codere SA delivers heat treatment systems specifically engineered to meet these stringent requirements, combining Swiss precision, robust process control, and full traceability.

Annealing is a heat treatment process used to increase the ductility of metals while reducing hardness, making materials easier to form, machine, or cold-work. 

It consists of heating the part to a specific temperature, holding it for a controlled duration, and cooling at a regulated rate. Typical annealing temperatures range from 450 °C to 1200 °C, with most industrial applications between 700 °C and 900 °C. Depending on the alloy, the process may be carried out in:

• Air
• Neutral atmospheres
• Protective or reducing atmospheres (hydrogen, nitrogen, gas mixtures)

At CODERE, we provide world class After-Sales Services in metal heat treatment, combining comprehensive customer support with metallurgical expertise. 

Our mission is to increase customer satisfaction, maximize the performance of the equipment and extend useful life.
