Glass wine bottles are very common in our lives and are also a very important product. Glass wine bottle manufacturers and processing fields will also distinguish the related quality of glass bottles. Therefore, we need to pay attention to some things about the production and production of glass wine bottles. The technicians of Shandong Yuncheng Ruisheng Glass Co., Ltd. will take you to understand.
Shoulder cracks; there are surface cracks on the shoulders, the temperature of the gob is too high or too low, and the opening of the preliminary mold or the forming mold is not stable. The positive blowing pressure is too large, the forming mold and the mold bottom are not properly matched, the forming mold clamp is severely worn, and the temperature of the forming mold is too high.
Shoulder is thin; part or all of the bottle shoulder is thin, the temperature of the gob is too high or uneven, the shape of the gob is too long or too short, and the blanking is incorrect. The preliminary mold is too hot, the preliminary mold is coated with too much oil, the positive blowing starts too late, the backward blowing pressure is small or the time is short.
Insufficient bottle shoulder The bottle shoulder is not completely formed; the temperature of the gob is too high or too low, the shape of the gob is not good or the thin material is not correct, and there is a lot of friction on the forehearth. The position of the positive blowing head is improper or the positive blowing pressure is too small, the positive blowing time is too short, the backward blowing pressure is too large or the time is too long, the initial shape is too hard, the reheating time is insufficient, and the initial mold or forming mold is too cold .
The bottleneck is defective and the bottleneck is bent; the mouth of the wine bottle is skewed from the neck to one side, and the temperature of the gob is too high. The die is too hot, the transfer center is not right, the positive blowing head is not flat or deviates from the center of the molding die, the positive blowing time is too short or the pressure is not enough, the bottle clamp is not concentric with the molding die. The bottle clamp is not level or the clamp bottle is pulled out too quickly, the forming mold is too hot or the forming mold is unstable.
