Etching film sheet: signage
Uses: used in high-end handicraft decoration, using sign etching machine production and processing
Etching process: coating → drying → exposure → development → etching → peeling
Equipment required: (metal etching machine equipment)
1 Coater: It is used for coating the workpiece as the protective layer. The ink on the coating machine is the most advanced and mature technology of today's technology. It is characterized by uniformity, time saving, labor saving, high output and consumables.
2 oven: used to paint 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 machine: used for photosensitive process, after the exposure, the surface pattern of the product is revealed, and then enters the etching process, which can realize continuous production.
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 ultrasonic cleaning machine: used to clean the excess ink after corrosion to get the finished product.
The above equipment is selected according to the actual output and the size of the workpiece. If you have any questions about the filter or any etched sheet, please call our sales phone for details.
