Factors Affecting The Smoothness Of Glass Wine Bottles

Because glass wine bottles have good sealing performance and barrier performance, they can keep the freshness of Baijiu in the bottle for a long time. Users often have wrinkled skin, bubble scratches and other phenomena in the process of using glass wine bottles. What factors affect the smoothness of glass wine bottles?

1. When the glass preform 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. Poor quality of oil in glass wine bottle molds can lead to insufficient lubrication of the molds, reduced dripping speed, and rapid changes in material types.

3. 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.

4. Uneven material dripping speed of the machine and improper adjustment of the air nozzle can cause the initial and molding temperatures of the glass wine bottle to be uncoordinated, which can easily create cold spots on the bottle body and directly affect the smoothness.

5. The scissor marks on the upper feeder are too large, and some bottles may have scissor marks on the bottle body after molding.

6. 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 uneven surface of the formed glass wine bottle.

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 machine speed is too fast or too slow, uneven glass wine bottle body and uneven bottle wall thickness will occur, resulting in spots.
