Screen Printing Engraving Process

The stainless steel engraving process involves several detailed steps to ensure precision and quality:

Cleaning

  • Step: Clean the stainless steel surface using the cleaning line.
  • Detail: This step removes all contaminants, ensuring the stainless steel is ready for further processing.

Screen Printing

  • Step: Apply resist paint using the screen printing line.
  • Detail: The screen-printed resist protects areas of the stainless steel that should not be engraved.

Drying

  • Step: Dry the resist-covered stainless steel using the drying line.
  • Detail: This ensures the resist is firmly adhered to the stainless steel surface.

Developing

  • Step: Develop the screen-printed stainless steel using the developing line.
  • Detail: This removes the unexposed resist, revealing the areas to be engraved.

Engraving

  • Step: Engrave the stainless steel using the stainless steel engraving line with the selected engraving solution.
  • Detail: The engraving solution removes the exposed stainless steel, creating the desired pattern.

Stripping

  • Step: Remove the remaining resist using the stripping line.
  • Detail: This leaves behind the final engraved stainless steel pattern, ready for any further processing.
