Conclusion
For major appliances, all pieces could be enameled by dry electrostatic application:

White and colors,
Acid resistance goundcoat, easy to clean, pyrolytic.

Today this process is compatible with continuous cleaning enamel and offers many advantages:

Easy to use,
Better working conditions,
Cost reduction,
Improved performance.
