Double Sides Gold Coating Machine Strong Adhesion Tin Gold Decorative On

Product Specification

Coating glassware with a two-sided gold coating using ion plating is a specialized process that can provide a luxurious and durable decorative finish. Ion plating, also known as ion beam sputtering or ion-assisted deposition, is a PVD technique that involves bombarding the coating material with ions to improve the film's properties and adhesion.

Here's how the process of applying a two-sided gold coating on glassware using ion plating typically works:

1. Surface Preparation: The glassware surface needs to be thoroughly cleaned and prepared before the coating process. This involves cleaning, degreasing, and sometimes etching the glass to create a rougher texture for better coating adhesion.
2. Ion Plating Chamber: The glassware is placed inside an ion plating chamber, which is a vacuum environment. The chamber is evacuated to create a high vacuum condition.
3. Coating Material Preparation: In this case, gold is the desired coating material. Gold is loaded into a crucible or target inside the ion plating chamber.
4. Ion Bombardment: The process begins by introducing an inert gas, typically argon, into the chamber. The gas is ionized to create a plasma. The plasma then bombards the gold target, causing gold atoms to be ejected from the target surface.
5. Film Deposition: The gold atoms released from the target travel as a vapor and condense onto the glassware's surface, forming a thin gold film. The ionized argon gas accelerates and assists the deposition process, improving the film's density, adhesion, and overall quality.
6. Rotation or Tilting: To achieve a two-sided gold coating, the glassware may be rotated or tilted during the deposition process. This ensures that both sides of the glassware receive an even and uniform coating.
7. Control of Thickness and Color: The thickness of the gold coating can be controlled by adjusting the deposition time and rate. This allows for customization based on the desired appearance and requirements. Different deposition parameters can also be employed to achieve variations in color and finish, such as rose gold or yellow gold.
8. Post-Coating Treatment: After the ion plating process, the coated glassware may undergo additional treatments, such as annealing or sealing, to enhance the coating's durability, scratch resistance, and overall performance. These treatments help ensure the longevity of the gold coating.

Coating glassware with a two-sided gold coating using ion plating can provide an elegant and high-quality finish. It offers improved adhesion, durability, and resistance to wear compared to traditional coating methods. This process is commonly used for high-end glassware, decorative items, and luxury products that require a prestigious and eye-catching appearance.

             
 
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 paining + Aluminum metallization process do 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 looks gold and not use the spraying painting process. 
 
After several cycles experiments, we found the proper coating process with strong adhesion.
