State-of-the-art pre-treatment and coating technology |
|
|
|
1. Tension levelling |
|
Tension levelling at the beginning of the manufacturing process guarantees an absolutely flat product. |
|
|
|
2. Cleaning of strips |
|
Perfect cleaning, removal of oxides, dirt and lubricants. |
|
During the cleaning process, the aluminium strip is cleaned within different zones.Cleaning is thus more efficient than conventional technologies and water can be re-used. |
|
|
|
3. Pre-treatment |
|
Pre-treatment is the key of the coil coating process. The pre-treatment is needed to increase the corrosion resistance and to ensure paint adhesion. During pre-treatment a conversion layer is chemically built up on the surface of the aluminium strip. |
|
|
|
4. Coil coating |
|
The paint is applied using rollers. All paint system is geared to match the requirements of the application. |
|
To achieve different results, different paint systems are used. The reverse side always has a protective lacquer |
|
|
|
5. Curing |
|
Depending on the paint system, the curing temperature lies between 200-300°C. |
|
In order to protect the environment as well as possible, the solvent vapour is used to heat the oven without gases escaping from the closed system. |
|
|
|
6. Continous quality control criteria monitored during the production |
|
* Color * Paint hardness |
|
* Paint thickness * Paint adhesion |
|
* Gloss * Formability |
|
|
|
7. Exit accumulator and re-coiling |
|
The coated aluminmum coil will be wind up and is ready for further processing |
Customer specified individual cut sizes of coils for sheets or strips
|
|
8. Packaging the finished product |
