On what basis do glass bottle manufacturers judge that glass bottles are qualified and can leave the

When the glass bottle factory is out of the bottle, the workers first look at the general condition of the product, and then after a period of annealing, the workshop director is carefully inspecting it. The general conditions are as follows, let us know,glasscookware.
     Deformation of the glass bottle body: Because the bottle entered by the forming mold has not been in a perfect shape, at this time, the temperature of the gob and the infection temperature are too high, and the glass bottle will often 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 uneven.
 Glass bottle body feeder marks: glass bottle manufacturers introduce feeder marks as the most common fault of glass bottles. It can be unusually thin, and some can only be created in reflected light. The most common parts are the mouth of the bottle, the neck of the bottle and the shoulder, and there are often forerunner marks on the bottle body and bottom of the bottle, which are caused by the temperature of the furnace.
 Uneven thickness of glass bottles: It is assumed that the glass bottle manufacturers have 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 mold temperature 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.
The environment of glass bottle cracks: The cracks have various shapes, some are creases, and some are very fine wrinkles. The primary reason 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 It is caused by adhesion on the cavity wall.
Bubble: The bubbles produced by glass bottle manufacturers during the forming process are often several large bubbles or several small bubbles that meet together, which is different from the evenly distributed small bubbles of the glass itself.
