As the core process of high-end glass bottle packaging, vacuum electroplating technology has become the key to creating a brilliant gold-plated effect due to its precision and stability. From glass blanks to finished products, every step is strictly controlled to ensure uniform plating, strong adhesion, and long-lasting texture——the core reason trusted by global spirits and beverage brands.
Core Workflow
1. Base Bottle Preparation & Surface Activation
Whether it’s a slender vodka bottle or a wide mason jar, all glass bottles undergo ultrasonic cleaning and plasma activation. This step completely removes surface contaminants and creates a micro-rough surface, laying the foundation for the uniform adhesion of the subsequent gold plating layer. Even in mass production, it can ensure the flawless texture of custom bottle designs.
2. Vacuum Metallization & Gold Layer Deposition
In a temperature and humidity-controlled vacuum chamber, glass bottles are fixed on rotating fixtures. Through high-temperature vaporization technology, 24K gold is converted into vapor, which is uniformly deposited on the bottle surface to form a rich and shiny gold-plated layer. For textured liquor bottles with transparent viewing windows, protective films are applied in advance to ensure the clear visibility of the internal liquor color.
3. Protective Top Coating & UV Curing
After gold plating, the glass bottles enter the coating station, where a layer of clear scratch-resistant polymer is sprayed and cured by UV light. This “golden shield” can effectively resist wear during transportation, while locking in the gold-plated luster, allowing wine bottles, juice bottles and other products to maintain their brilliance during long-term use.
4. Dimensional & Adhesion Quality Checks
Technicians use electronic gauges to verify the plating thickness and perform tape tests to ensure adhesion meets standards. In addition, color consistency checks are conducted on bulk wine bottles to ensure each batch of products meets the brand’s luxury visual standards, which is also our core advantage as a high-quality glass bottle wholesaler.
5. Bulk Packaging & Global Logistics Prep
Finally, gold-plated liquor bottles, mini liquor bottles, and bulk glass bottles are packed into foam-lined, eco-friendly wooden crates. Custom bottles (such as irregular champagne bottles and faceted vodka bottles) are protected by individual liners, while wholesale wine bottles use stackable wooden crates to optimize international transportation efficiency.
Core Advantages of the Process
Vacuum electroplating not only endows glass bottles with a luxury texture but also offers practicality: uniform and flawless plating, strong adhesion that is not easy to peel off, scratch resistance suitable for logistics, and environmental compliance meeting global standards. Whether it’s bulk orders or custom designs, this process can meet the strict requirements of high-end brands for packaging.
