In 2010, around 56.6 million pairs of sunglasses and frames were produced, of which around 45% were in metal and the remainder in plastic.
The manufacturing process for metal frames has approximately 70 phases, beginning with the production of basic components such as rims, temples and bridges, which are produced through a moulding process. These components are then welded together to form frames over numerous stages of detailed assembly work. Once assembled, the metal frames are treated with various coatings to improve their resistance and finish, and then prepared for lens fitting and packaging.
Plastic frames are manufactured using either a milling process or injection moulding. In the milling process, a computer-controlled machine carves frames from coloured plastic sheets. This process produces rims, temples and bridges that are then assembled, finished and packaged. In the injection moulding process, plastic resins are liquefied and injected into moulds. The plastic parts are then assembled, coated, finished and packaged.
