[Processing Example] Etching Processing, Black Dyeing, Black Treatment

Produced while suppressing warping and distortion in the finish! Depending on your request, partial black dyeing can also be accommodated.

Etched products are used as light shields (aperture plates) for built-in camera modules in smartphones and mobile phones. To absorb light, they are generally black in appearance. There are also specifications that stack multiple plates to allow for fine adjustments of hole sizes. The holes are usually circular, but can also be of irregular shapes. However, with Hirai Precision Industry's etching process, it is possible to easily create irregular shapes. **Advantages of creating apertures through etching:** - Compared to machining (laser processing, wire electrical discharge machining, cutting), etching can produce parts with reduced warping and distortion. - It can process thin foils with a thickness of 0.005mm. - Not only etching, but also black surface treatment can be processed and delivered consistently. *For more details, please refer to the PDF document or feel free to contact us.*
