Quality Control Process of Glass Bottle

The forming process is the most important part of the whole manufacturing process. If you are a newbie, it’s okay, you can learn more useful information.

1, Temperature Management
During the molding process, the mixed raw materials are melted in a hot melting furnace at 1600°C. Temperatures that are too high or too low will result in a higher defect rate, and that is why our engineers monitor the temperature every two hours.

2, Monitoring the normal functioning of equipment
During the molding process, it is necessary to continuously monitor the molding performance, which helps to solve problems and prevent the high-volume production of defective products.
Each mold has a specific mark. Once a product problem is found, it helps us to quickly trace back to the source, and solve the problem immediately.

3, Finished bottle inspection
Our quality inspector will randomly pick up a bottle from the conveyor belt, plays it on the electronic scale to check whether the weight meets the specification, then put it on the rotating base and rotate it up to see if the horizontal axis of the glass bottle is perpendicular to the ground, whether the wall thickness is uniform, whether there are air bubbles, and we will check the mode immediately once we find a problem. The inspected glass bottles are then transferred to an annealing machine.

4, Appearance Inspection
Before we pack the bottles, each bottle passes through a light panel where our inspectors perform another appearance inspection.
Any defective bottles will be screened and discarded immediately. Don’t worry about these bottles will be wasted, they will be sent back to our raw material department where they will be crushed and melted down again to make new glass bottles. Glass cullet as part of the raw material, and that is the reason why glass is a 100% recyclable.

5, Physical check
After passing the above inspections, there is another quality control procedure called physical checks. Our inspection items include the inner diameter, the outer diameter, the height of the bottle, and the thickness of the mouth.

6, Volumetric check
During the volumetric check, first, we weigh the empty bottle and record the reading, then fill the bottle with water and weigh it again. By calculating the difference in weight between the two measurements, we can see if the volume of the sample bottle is aligning with the specification.
