As a leading global glass liquor bottle manufacturer and supplier, our core competitiveness stems from a refined and precise production process. From 1500°C molten glass to finished bottles that meet the requirements of high-end spirits brands, every link embodies technology and craftsmanship, ensuring consistent quality, pressure resistance, and aesthetic value for each batch of products.
1. Gob Feeding & Thermal Precision
The production process starts with automated gob feeders, which accurately deliver measured doses of molten glass (at a temperature of 1500°C) to individual section (IS) machines. This precise dosing is the foundation for product consistency—whether it’s pressure-resistant beer bottles, champagne bottles, or whiskey bottles and custom bottles pursuing elegant curves, the uniform wall thickness is established here.
2. Parison Formation & Blow Molding
After the measured molten glass enters the mold, it is first pressed into a “parison” (a preliminary bottle shape). Subsequently, the parison is transferred to a blow mold, where high-pressure gas inflation makes it fully fit the inner wall of the mold, ultimately presenting the sleek lines of vodka bottles and the intricate details of tequila bottles. Meanwhile, mason glass jars, water glass bottles and other products also take their initial shape at this stage, sharing the same precise craftsmanship standards as high-end liquor bottles.
3. Annealing & Stress Relief
Freshly molded glass products have residual internal stress and are prone to cracking if cooled directly. Therefore, all products—from compact mini liquor bottles to thick wine glass bottles—are immediately sent to annealing ovens for controlled cooling. This process completely eliminates internal stress, endowing glass liquor bottles, juice bottles and other products with excellent impact resistance, ensuring they remain intact even during bulk long-distance transportation.
4. Real-Time Quality Assurance
We have integrated an in-line inspection system into the production line, which uses high-definition cameras and sensors to real-time check for product defects, dimensional accuracy, and surface clarity. Even minor imperfections are screened out, ensuring that all alcohol bottles, wine bottles and other products entering the subsequent links meet top-quality standards. This is the core guarantee that makes us a trusted supplier for glass bottles wholesale and wine bottles wholesale.
5. Custom Branding & Bulk Packaging
The final stage of the production process focuses on product value-added and protection. On the cold-end line, we implement customized brand logos through silk-screen printing, embossing, metallic coatings and other processes, making vodka bottles and whiskey bottles stand out on the shelves. Subsequently, bulk glass liquor bottles, mini liquor bottles and other products are packed into eco-friendly, shock-resistant packaging materials to provide comprehensive protection for long-distance transportation.
This complete process from molten glass to finished product packaging is the core strength that enables us to provide high-quality, sustainable packaging solutions for global spirits brands. Whether you need bulk customization or standard products, our precision craftsmanship can meet your needs.
