What causes the bubble scratches in glass bottle molding?

1. When the glass blank falls into the initial mold, it cannot accurately enter the initial mold, and the friction with the mold wall is too large, forming folds. After positive blowing, the wrinkles spread and amplify, forming wrinkles on the glass bottle body.

2. The initial mold and the mold of the glass bottle are of poor material, the density is not enough, and the oxidation is too fast after high temperature, forming small concave spots on the mold surface, causing the surface of the molded glass bottle to be uneven.

3. The glass liquid in the kiln is not clean or the material temperature is uneven, which will also cause bubbles, small particles, and small hemp blanks in the output glass bottles.

4. The machine dripping speed is uneven, and improper adjustment of the wind nozzle will cause the initial mold and the mold temperature of the glass bottle to be uncoordinated, which is easy to create cold spots on the glass bottle body, directly affecting the finish.

5. If the speed of the row machine is too fast or too slow, the glass bottle body will be uneven, the bottle wall will be of different thicknesses, and there will be spots.

6. The scissor marks of the feeder are too large, and the scissor scars appear on the bottle body after the individual glass bottles are formed.

7. The design of the initial mold is unreasonable, the mold cavity is large or small, and after the material is dripped into the molding mold, it is blown and diffused unevenly, which will cause spots on the glass bottle body

8. The poor quality of the glass bottle mold oil will cause insufficient lubrication of the mold, reduce the dripping speed, and change the material shape too quickly.
