1. Hot coating.
Thermal coating is performed after the glass bottle is formed and before annealing. After the glass bottle is formed, it is slowly cooled to 500-600 degree , and a layer of metal coating (such as tin oxide, titanium oxide, tin chloride, etc.) is sprayed on the surface of the glass bottle. Containers, hot coating. Thermal coating is performed after the bottle is formed and before annealing. After the glass bottle is formed, it is slowly cooled to 500-600 degree and metal coating (such as tin oxide, titanium oxide, tin chloride, etc.) is applied. ) spray on the surface of the container.

2. Cold coating.
Cold plating is performed after the glass bottle is annealed. Spray monostearate, polyethylene, oleic acid, silane, silicone or other polymer emulsion into mist, and adhere to the surface of a glass bottle at a certain temperature (the temperature inside the bottle depends on the spray material, about 21 to 80 degree ) .Form a protective layer with wear resistance and lubricity.
