Benefits of technology

The patent describes a coating that can be applied to the edge of a glass enclosure's rim, which helps to insulate it from other flaming structures. This results in improved safety and reliability in the manufacturing process.

Problems solved by technology

However it is difficult to make variation of colors with economical ways.
Another issue was durability, especially the application to portable devices, which requires the strength against impact (such as falling down to floor).
However, compositions of the chemically toughened glass are limited, giving difficulty for obtaining a glass composition that meets other requirement such as appearance.

example 1

[0063]Glass enclosure was shaped by casting melted Schott LAS80 glass to have dimension of 100 mm×60 mm rectangle shape with curved corner of radius 5 mm and 3 mm depth concave with uniform thickness of 1.0 mm.

[0064]One set of mold is made with stainless-steel SUS420 by Numerical Control machining. First mold has concave which corresponds to the outer dimension of above glass enclosure. Second mold has convex shape and it is made to give uniform distance of 1 mm from the inner surface of above glass enclosure when two mold and glass enclosure are combined.

[0065]Acrylic resin and black carbon powder was mixed with 99:1 ratio for black colored thermoplastic elastic material by roll mill.

[0066]Glass enclosure was fixed in the concave on first mold by vacuum via hole through mold body. Then second mold was fixed on the first mold to make space between second mold and glass enclosure. The molds and glass enclosure were heated up to 110 degree C. and the colored thermoplastic elastic mate...

example 2

[0067]The Glass enclosure prepared in Example is used. Colored layer printed film was prepared as following process. 100 um thick polyethylene terephthalate film was used as a base film. Release layer was made by coating silicone resin on the film surface. Ink made of acrylic resin and color dye was coated by offset printing on the film to make colored decoration pattern.

[0068]The glass enclosure was set on first mold and fixed with vacuum and above printed film was positioned to cover the glass enclosure with direction which the printed side opposite to glass enclosure and base film surface facing to glass enclosure. Second mold was set over the glass enclosure and printed film and the film was fixed with two molds in the whole area out of glass mold. The molds and glass enclosure were heated up to 110 degree C. and the thermoplastic elastic material was heated up to 120 degree C. and injected into the space between the second mold and the glass enclosures by pumping system through...
