AI Technical Summary
During the AF coating process, 3D curved microcrystalline glass is difficult to stick to the PE film due to the height of the four-side arc edges on the concave surface, which is easy to fall and cause overplating problems.
A anti-spill structure is designed, including bonding a high-viscosity layer at the rear end of the arc-shaped bent portion and pasting it on a PE film, which opens an exhaust hole in the straight plate portion.
Through the design of high viscosity layer and exhaust holes, the glass prevents falling and over-plating, improves product yield, and facilitates exhaust during vacuum coating, ensuring good adhesion between the glass and PE film.
