Photo Etched Film for Precision Filtration

Photo etched film, also known as photochemical etching or photo etching, is a manufacturing process used to produce precise metal parts with intricate patterns or designs, which is commonly used in the process of high quality filament spinning, in order to avoid the clog of spinneret capillaries.

Photo etched film offers several advantages in manufacturing compared to traditional methods like stamping or laser cutting. It allows for high precision, intricate patterns, and complex designs with tight tolerances. It is also a cost-effective method for producing small to medium-sized production runs. Furthermore, it eliminates the need for expensive tooling and reduces the lead time for prototyping and production.

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.
