How to determine whether the bonded glass bottle is qualified for release

After the production of bonded glass bottles, each bottle needs to be inspected before qualified products can be packaged and shipped. The specific efficacy of the bottles depends on the actual situation. When producing the bottles, the team of machine workers first looks at the general condition of the products, and then after a period of annealing, the workshop director carefully inspects them. There are several general situations that can be understood by us.

The deformation of the glass bottle body of the key protection product: Because the key protection product glass bottle that is molded into the mold is not yet fully formed, the high temperature of the material droplet and the temperature of the action often cause the glass bottle to collapse and deform. If the upper part of the bottle body is too heavy, it will also be like this. Occasionally, if the bottom of the bottle is not cooled to the corresponding temperature, it will be marked with conveyor belt marks, making the bottom of the bottle unyielding. Body material trace: Body material trace is a common problem with glass bottles. It can be exceptionally fine, some of which can only be created in reflected light. The common areas of occurrence are the bottle mouth, neck, and shoulders, as well as the material path marks on the bottle body and bottom, which are caused by the temperature of the furnace. Uneven thickness: Assuming that the glass material droplet temperature is uneven during the processing of the key protection bottle manufacturer, the high temperature part has low viscosity and is easy to blow thin, while the low temperature part has high resistance and is thicker. In addition, the temperature of the mold is uneven, with the glass on the high temperature side cooling slowly and easily blown thin, while the glass on the low temperature side cools quickly and is blown thick. The environment of cracks: Cracks have various shapes, some are creases, and some are thin wrinkles in patches. The first reason for their occurrence is that the material droplets are too cold, too long, and do not fall on the center of the initial mold, but adhere to the mold cavity wall. Bubbles: The bubbles generated by glass bottle manufacturers during the forming process are often several large bubbles or small bubbles that gather together, which is different from the uniform distribution of small bubbles in the glass itself.
