A method for manufacturing vehicle mirrors

摘要

Molding a carrier base from plastic having a curved base surface formed into a fixed shape prior to receiving a mirror coating. Sputtering a first mirror coating layer selected of chromium onto the curved base surface, wherein the first layer has a light reflectivity in the range of approximately 60% to 65% of visible electromagnetic radiation. Sputtering a second mirror coating layer of aluminum onto the first layer so that the second layer has a light reflectivity of at least about 80% of visible electromagnetic radiation and a maximum thickness of approximately 20 % of the thickness of the first layer. The first and second mirror coating layers are applied to the curved base surface to have a combined layer thickness in the range of approximately 5mm to 1µm. Applying an anti-scratch coating onto the second mirror coating layer to resist damage to the first and second mirror coating layers.
