Recycled 460ml brown beer bottle

At the start of the automated production workshop, high-purity quartz sand, soda ash, and a special brown pigment are precisely mixed and continuously melted in a high-temperature kiln at 1500°C, transforming into a uniform, translucent amber-colored molten glass. As this molten glass passes through a constant-temperature flow channel, an automated dispensing device cuts it into "glass droplets" of uniform weight. The tolerance for each droplet is strictly controlled within ±2 grams, ensuring the precise volume of the final 460ml bottle.

After forming, the glass bottles are immediately placed in an annealing furnace, where they undergo a gradual cooling process from 280°C to 60°C to eliminate internal stress and prevent cracking during subsequent use. After cooling, the bottles undergo three quality inspections: an optical inspection system scans the bottle walls, accurately identifying bubbles or cracks larger than 0.3 mm; a leak-proof testing machine pressurizes the bottles to 1.2 MPa and observes them for leaks while submerged in water; and a weight tester ensures that the weight of each bottle remains stable within the 315-325g range. Qualified products are transported via a conveyor belt to a polishing station, where the burrs on the bottle necks are meticulously treated. Finally, they are cleaned with high-pressure sprays, dried, and packaged for storage, awaiting subsequent beer bottling.
