Glassware Post-Processing Finishing

Main Finishinges: Printing, screen printing, decal, plating, plating with engraving, rainbow plating, acid, flocking

Here we will introduce 4 finishes which used most widely. 

1.Spraying

Spraying is to spray the color on the transparent glass, and then baked in the furnace at 160-210 degrees for about 40 minutes.

Spraying is divided into internal spraying and external spraying. The different is the bottle painted outside can be scratched with a knife; the inner spray can not be scratched, and the outer bottom of the bottle is transparent.

2.Screen Printing 

The glass body should be clean and fixed on the screen, then rolled against the screen. The pattern would be printed on the bottle. Put it into the heating furnace with 150 degrees for about 40 minutes, and check whether the pattern is complete and clear.

3.Frost

3.1 Sanding: The air compressor sprays silicon carbide at high speed onto the glass surface to destroy the smooth surface. The sanded glass wall should be thick, otherwise it will have a higher damage. The higher the sand mesh, the finer the surface feels.

3.2 Pickling: Corrosion of the glass surface by soaking strong acid, destroying the smooth surface.

4.Plating

In the vacuum plating machine, the tungsten wire is heated by a strong current so that the aluminum wire hanging on the tungsten wire will be dissolved, and then the aluminum is evaporated and dispersed in various parts under vacuum and adhered to the glass. After cooling and crystallization, it becomes Aluminum film.
