In the production of glass bottles, when the bottles are released, the line-up machine workers first look at the general condition of the product, and then after a period of annealing, the workshop director will check carefully. The general conditions are as follows, for everyone to understand.
Deformed glass bottle
Because the molded bottle has not been completely shaped, the gob temperature and action temperature are too high at this time, which will often cause the glass bottle to collapse and deform, even if the upper part of the bottle is too heavy. Occasionally, if the bottom of the bottle is not cooled to a certain temperature, the traces of the conveyor belt will be printed on the bottom of the bottle, making the bottom of the bottle unyielding.
Glass bottle body traces
According to the glass bottle manufacturer, material track is the most common defect of glass bottles. It can be very thin, and some can only be created in reflected light. The parts that often occur are the mouth of the bottle, the neck and the shoulder, and the body and bottom of the bottle often have material path marks, which are caused by the temperature of the furnace.
The thickness of the glass bottle is uneven
If the glass bottle manufacturer is in the process of processing, the temperature of the glass gob is not uniform, the part with high temperature has low viscosity and is easy to blow thin, and the part with low temperature has high resistance and is thicker. In addition, the temperature of the mold is uneven. The glass on the side with high temperature cools slowly and is easy to blow thinly.
The environment of cracked glass bottles
Cracks have various shapes, some are creases, and some are very thin wrinkles in pieces. The main reason is that the gob is too cold, the gob is too long, and the gob does not fall in the center of the initial mold and sticks to the wall of the cavity. happened above.
bubble
The bubbles produced by the glass bottle manufacturer during the forming process are often a few large bubbles or a few small bubbles gathered together, which are different from the evenly distributed small bubbles of the glass itself.
