Etching film name: signage

 

Uses: It is used for the emergency indication function of the walkway in public places to prevent the occurrence of safety hazards. It is an indispensable indicator sign in life and is produced and processed by using stainless steel sign etching machine.

 

Etching process: painting → drying → exposure → development → etching → peeling

 

Equipment required: (metal etching machine equipment)

 

1 Air compressor: used to spray ink on the workpiece as a protective layer;

 

2 Oven: used to coat the ink to dry, prevent ink sag, deepen curing;

 

3 Exposure machine: used for the local photosensitive ink on the light-solid workpiece to form image transfer. The UV-wavelength ultraviolet light is emitted by turning on the ultraviolet light to transfer the pattern on the film to the workpiece coated with the photosensitive ink;

 

4 developing tank: used for photosensitive process, after the exposure, the surface pattern of the product is revealed, and then enters the etching process, and the exposed workpiece is immersed in the developing tank until the pattern appears;

 

5 Etching machine: used to corrode the exposed metal part of the workpiece, and use an etching solution to remove some metal corrosion equipment by high pressure spraying.

 

6 Film removal tank: used to clean the excess ink after corrosion to obtain the finished product, and the etched workpiece is placed in the film-removing tank until the ink is completely removed.

 

The above equipment is selected according to the actual output and the size of the workpiece. If you have any questions, please call our sales phone for details.
