We share a technical passion with our historical partners in France and Italy (raw materials) and more recently, in Germany. Bruno Chaussignand accompanies his teams throughout manufacturing to verify that the glasses produced are in synch with the initial project. It takes 3 months and 50 manufacturing steps to make a pair of Bruno Chaussignand glasses. Each step is controlled by a specialist who ensures a minute and delicate production of our collections.
The colors are essential, they highlight the design and are specific to each model. We want them to be different, bright and harmonious so they carry a little spark.
The acetate plates from which our glasses are cut are made of cotton flower and acetone, natural materials that protect against the risk of allergies.
The layout of the front and temples is made by a 5-axis cut: the glasses come to life under the movements of the machine and the technician's watchful eye.
To soften it and to embed the metal structure of the frame, the acetate is heated to 310°C in a press. This step solidifies the skeleton of the branches and fixes their hinges.
Discreet signature: a golden stamp representing the brand's historic emblem is inserted at the end of the temple spatula, then covered with resin.
The front is pierced on the sides to be able to place the metal yoke (tenon) which will allow it to be associated with the branches.
Essential step for wearing comfort: the front and temples are slightly curved.
Heated a second time, the pieces are then positioned on a mold which will give them the ideal curve.
They will then pass through an ultrasonic cold water bath to stabilize their shape.
For 3 days the acetate pieces are polished in barrels of wood shavings and wax which will allow the acetate to bring forth its shine and softness.
Specialists hand-assemble the front and temples of each frame. We use German OBE hinges which are equipped with Teflon-coated screws: a material that protects it's surface and gives it longevity.
The final step that gives the frame its identity: its name, size and origin are inscribed inside the temples.
