Tempering: a form of heat treatment
What is tempering?
Tempering refers to heating the material over a longer period of time (from a few minutes to several hours). The component is heated evenly to just below its melting temperature. This increases the mobility of the molecules and optimizes the structure, compensating for structural defects. Any gases (air bubbles) are expelled. Performance characteristics such as strength, chemical resistance, and heat resistance are improved.
How do I proceed? (3 phases)
- Heat evenly and slowly (maximum 20°C per hour).
- Maintain a constant temperature over a longer period of time.
- Cool very slowly and evenly.
The duration of the steps and the temperature depend on the materials used. You can find information in our processing instructions or give us a call—we will be happy to advise you.
Special industrial ovens are used for tempering. Ask a painter in your area if they can help you.
However, small parts can also be tempered in a standard oven.
Do not use your oven at home.
Please note that the temperature settings on the oven are not accurate. Use a temperature sensor and temper a test piece beforehand.
Another tip!
Industrial plastic molded parts may contain residues of release agents from the manufacturing process, which prevent an optimal bond between the component and the synthetic resin.
To remove these residues, temper the parts for 1-2 hours at 60°C beforehand.
