What is the reason for the uneven thickness of glass wine bottles?

1. Glass wine bottle shoulder: a part of the glass wine bottle is very thin and cannot meet the required model standard. Most of the reasons for the shortcomings of the thick-walled tube of the bottle shoulder are that the relative part of the raw material embryo is not properly frozen or moistened, resulting in The temperature is too high, or the start time of the positive blowing inspection is too long, resulting in excessive stretching and bending of the raw material blank.
2. Thin glass bottle: The key to this shortcoming is part of the thickness of the glass bottle, or it does not meet the standard of the standard thin-walled model. The reason is that the reheating time of the prototype raw material embryo is usually too long. The start time of the blowing inspection is delayed, the wall thickness of the glass bottle may also be uneven, and the wrong operation of the mold industrial architectural coating causes the mold to be very dirty, the temperature difference between each position of the molding mold is particularly large, and the molding mold is not cooled properly.
3. The bottom of the glass wine bottle is thin: the thickness of the bottom of the glass wine bottle does not meet the standard model standard, the initial contact time of the mold is too long or the reheating time is insufficient, the temperature of the preform is too low, and the glass containing reinforced rubber does not spread well; The blowing check starts early, or the blowing time is too long, the pre-weight of the bottle is not heated enough, the positive blowing check starts early, or the positive blowing check takes too long, or the timing execution time of the needle (spindle) is not appropriate Chances are high.
