What Are The Factors That Cause Glass Wine Bottles?

During the production process of glass wine bottles, non-standard manufacturing processes or other external factors can lead to defects in the bottles. One of the common defects is that the surface of the wine bottle is not smooth. So, what are the main factors that cause the glass wine bottle to be not smooth?
1. When the glass blank falls into the initial mold, it cannot accurately enter the initial mold, and there is excessive friction with the mold wall, forming wrinkles. After blowing air, the wrinkles diffuse and enlarge, forming wrinkles on the body of the glass wine bottle.
2. The scissor marks on the upper feeding machine are too large, and some bottles have scissor marks on the bottle body after forming.
3. The initial and molding materials of glass wine bottles are poor, with insufficient density. After high temperature, they oxidize too quickly, forming small pits on the surface of the mold, resulting in an unclean surface of the formed glass bottle.
4. Poor quality of glass bottle mold oil can lead to insufficient lubrication of the mold, reduced dripping speed, and rapid change of material type.
5. The initial mold design is unreasonable, with large or small mold cavities. After the material drips into the forming mold, it spreads unevenly during blowing, which can cause spots on the body of the glass wine bottle.
6. Uneven dripping speed of the machine and improper adjustment of the air nozzle can cause temperature imbalance between the initial and molding temperatures of the glass bottle, which can easily create cold spots on the body of the glass wine bottle and directly affect its smoothness.
7. Unclean glass liquid or uneven material temperature inside the kiln can also cause bubbles, small particles, and small hemp billets to appear in the produced glass wine bottles.
8. If the speed of the row and column machine is too fast or too slow, uneven glass bottle body and uneven bottle wall thickness will occur, resulting in spots.
