Keyrings with integrated magnets for EIGHT & BOB

The project

Archicercle manufactured bespoke keyrings for EIGHT & BOB with a specific function: to house the magnet used to operate an opening and closing system. Each piece combines a black acrylic body with the brand’s logo engraved on the front.

Each keyring consists of two pieces of black acrylic, one 2 mm thick and the other 3 mm, bonded together. Manufacturing brought together cutting the body, recessing the surface to house the magnet and engraving the logo.

The outline and hole were cut using a CO₂ laser. To create the magnet recess on the back, the laser power was increased and several passes were made with the same laser, removing material from the surface before the magnet was inserted.

The logo was then engraved on the front using a fibre laser. The two laser technologies therefore had distinct roles: CO₂ was used to cut and recess the acrylic, while the fibre laser personalised the visible face.
