Industrial vitreous enamelling processes

  
Traditionally vitreous enamelling of mild steel was done with a so-called wet applied two coats two fires process, which consists of the following eight sequential process steps :
  1. Pretreatment
  2. Enamel preparation
  3. Wet enamel application
  4. Drying
  5. Firing
  6. Wet enamel application
  7. Drying
  8. Firing

Over the years new application equipment and smarter enamelling processes, such as direct-on white and 2 coats one fire, were developed.

The selection of a vitreous enamelling process is mainly driven by the following aspects :

  • Functional and/or esthetical coating requirements

  • Complexity of coated object

  • Substrate quality and chemical composition

  • Environmental considerations

  • Hourly production capacity
