Inspection method for glass wine bottles

Glass wine bottles are the most commonly used glass bottles in daily life, but when producing glass wine bottles, glass must be inspected for glass wine bottles, so what are the inspection methods? Let's find out together!

1. For manufacturers specializing in the production of glass wine bottles, most of them rely on the mold provided by the customer, or according to the drawings and the newly opened mold for the sample bottle. For the key dimensions of the mold that will affect the molding, it is necessary to communicate and negotiate with the customer when the mold is opened. , to reach a consensus on the revision of key dimensions. Therefore, all molds must be matched with the die, initial mold and finished mold of the mold when entering the factory, and inspected according to the drawings or customer requirements.

2. The first 10-30 products are produced before the mold is loaded into the machine, and 2-3 products are drawn from each mold for size and specification inspection. The inspection focus is on the height of the mouth; the inner and outer diameter of the mouth; whether the base is engraved Correct and clear; whether the bottle body pattern is correct.

3. When the bottle just comes out of the annealing line, the quality inspection team will limit each molded product to 2-3, and inspect all aspects according to the drawing. Measure the weight, the inner and outer diameter of the mouth, and if necessary, fill the bottle with water, use the cap provided by the customer as a physical assembly, and check whether the cap can be placed in place and whether there is water leakage. And for internal pressure, internal stress, acid and alkali resistance test.

4. If the mold is not changed, every 2 hours, draw 2 pieces of each mold to test the capacity and material weight, and also check the inner and outer diameter of the opening to prevent the cover from being easily stained with oil during use. Leakage occurs.

5. During the manufacturing process, a new mold may be replaced due to the mold. Therefore, after the mold is changed, the molding workshop must notify the quality inspection workshop immediately. And process inspection, to prevent quality problems caused by ignorance of quality inspection after mold change.
