What tests do glass bottle manufacturers need to perform before leaving the factory for wine bottles?

1. Observe whether the glass bottle mouth of the wine bottle is flat and whether there are any protrusions or dents.

2. Check whether the production process of wine bottles and glass bottles is exquisite, and whether there are any seam errors, seam cracks, or rough seams.

3. Is there any deformation, flat bottom, or protrusion on the glass bottle body of the wine bottle.

4. Conduct tests on capacity, cold and hot durability, and water leakage to check the quality of wine bottles and glass bottles.

5. Measure whether the size of the wine bottle glass is strictly in accordance with the glass mold.

6. Measure the capacity and material of wine bottles, as well as the inner and outer diameters of the opening. If necessary, fill the bottle with water and assemble it with a customer supplied lid to check if it can be properly sealed and if there is any water leakage. And conduct internal pressure, internal stress, and acid and alkali resistance tests.

7. If it is found that the produced wine bottle glass bottle product is far from the mold specifications and parameters, it indicates that the quality of the product is unqualified.

8. Observe whether the glass bottle of the wine bottle is smooth and free from turbidity, bubbles, cracks, and stains.

9. A good glass bottle manufacturer can minimize the error between wine bottle glass bottle products and molds.
