What standard is the glass bottle inspection index certificate based on? It is roughly divided into five steps, which are listed below for your reference and learning,glasscookware.
1. Deformation of the glass bottle
Since the bottle entered by the forming mold has not been completely set, the gob temperature and the action temperature are too high at this time, which often causes the glass bottle to collapse and deform, even if the upper part of the bottle body is too heavy. Occasionally, the bottom of the bottle is not cooled to a certain temperature, which will print the lines of the conveyor belt and make the bottom of the bottle unyielding.
Second, the glass bottle body material traces
Glass bottle manufacturers introduce sprue marks as the most common fault of glass bottles. It can be incredibly thin, some only created in reflected light. The most common parts are the bottle mouth, neck and shoulders, and the bottle body and bottom of the bottle often have forerunner marks, which are caused by the temperature of the furnace.
3. The thickness of the glass bottle is uneven
Assuming that the glass bottle manufacturer has uneven temperature of the glass gob during the processing process, the part with high temperature has low viscosity and is easy to blow thin, and the part with low temperature has large resistance and thicker. In addition, the temperature of the mold is uneven. The glass on the high temperature side cools slowly and is easy to blow thin, and the glass on the low temperature side is blown thick due to the fast cooling of the glass.
Fourth, the glass bottle crack environment
Cracks have various shapes, some are creases, and some are very fine wrinkles in sheets. The primary reason for the occurrence is that the gob is too cold, the gob is too long, and the gob does not fall on the center of the initial mold and adheres to the cavity wall. happened above.
5. Bubbles
The bubbles produced by glass bottle manufacturers during the forming process are often several large bubbles or several small bubbles that are combined together, which is different from the evenly distributed small bubbles of the glass itself.
