Photo Etched Film for Precision Filtration
Photo Etched Film
It adopts chemical etching process to process various complex shapes of high-precision mesh and graphic on various metal sheets according to the designed geometric figures, which cannot be completed by various mechanical processing methods.
Material
Stainless steel sheet, copper sheet, aluminum sheet and various alloy sheets.
The Principle Of Etching
Etching is also called photochemical etching. It refers to plate making through exposure, after development, the protective film of the area to be etched is removed, and the etching site is contacted with a chemical solution to achieve the effect of dissolution and corrosion to form the required shape and size.
Production Process
① Cut the metal plate according to the requirements of the drawing.
② Design graphics on the metal plate.
③ Prepare or choose different chemical solutions according to different materials.
④ Cleaning plate-inking-drying-exposure-development-oven drying-etching-ink removal-cleaning and drying.
Technical Standard
① Etching area: 500mmx600mm.
② Material thickness: 0.01mm-2.0mm, especially suitable for ultra-thin plates below 0.5mm.
③ Minimum wire diameter and minimum hole diameter: 0.01-0.03mm.
