As a leading global glass bottle manufacturer and supplier, our continuous annealing line is the “unsung hero” guaranteeing product quality. Through our factory-exclusive video, you will intuitively witness how freshly molded glass bottles undergo strengthening treatment in precision equipment—rows of liquor bottles, vodka bottles, and custom glass bottles are neatly arranged, secured by rotating fixtures, and smoothly pass through the annealing tunnel to receive precise thermal conditioning.
Why is this core process crucial? Freshly blown glass bottles contain residual internal stress. Without annealing, they are prone to cracking during global transportation vibrations, temperature changes, or daily use. Our continuous annealing line, through standardized processes, ensures every product—from exquisite champagne bottles to pressure-resistant beer bottles, and from mini liquor bottles to large-capacity wine bottles—possesses durability to withstand long-distance shipping tests.
In the video, you will see the full process from molding to cooling: glass bottles move at a constant speed through the 60-meter tunnel, and the stable design of the fixtures ensures uniform heat exposure, protecting the complex shapes of custom bottles while maintaining the transparent texture of wine bottles. This is the confidence that makes us a reliable glass bottle factory—delivering consistent high quality for every batch of bulk glass bottles and wholesale wine bottles.
Whether for spirits packaging, beverage containers, or storage jars, the structural stability endowed by the annealing line is key to ensuring products reach global customers safely. Watch the full factory video to witness how we empower quality with technology, providing your brand with glass packaging solutions that stand the test of time.
