2-Sides Gold Color Coating Machine, Glass Inside & Outside Gold Colors Coating
PVD ion plating gold color on glassware is well known and used in the market, however, to improve the adhesion of coated film, the bonding layer is always applied before TiN/ZrN gold coating, which has an issue that from inside seeing through, it reflects the metal layer color: silver or dark silver.
If we use the Spraying painting + Aluminum metallization process we can generate a double-sides gold color result, but the adhesion is weak and more complicated process, it makes the labor cost and production cost is increased.
In Nov. 2020, we received the request from middle east customer: double-sides gold and not use the spraying painting process.
After several cycles of experiments, we found the proper coating process with strong adhesion.
