Multi depth etching on Linn wireless speaker


Depth Etching

Material Specification

Linn products manufacture exceptionally high quality hi-fi and audio equipment. They required a bespoke speaker grille using multidepth etching to also incorporate their logo into a single piece using a unique material specification.

Photofab’s purchasing team were able to source and meet the material criteria, with 430 Bright Annealed stainless steel used for the grille. The team carried out product realisation meetings with their research and development team in order to offer the most effective and efficient methods of manufacturing. With dedicated account managers on the case, Photofab was able to ensure excellent customer service.

After presenting Linn with several customised chemical etchings, the favourite was put into an initial production batch, with the material measuring 0.5mm thick. Meeting Linn’s high standards, the grille went into production on their new wireless speaker.

With Photofab’s high levels of accuracy, anything from 10 microns (0.0004”) to over 0.5mm (0.020”) can be removed, giving a detailed, burr free finish with very fine apertures in the speaker’s design. The gaps were measured precisely across the entire grill to ensure the customer requirements and tolerances were met, measuring 3.4mm in height and 1.9mm in width.
