After the glass bottle is produced and formed, sometimes there will be a lot of wrinkled skin, bubble scratches, etc. on the bottle body, which are mostly caused by the following reasons:
1. When the glass blank falls into the preliminary mold, it cannot accurately enter the preliminary mold, and the friction with the mold wall is too large to form creases.
2. The scissors marks on the upper feeder are too large, and the scissors scars appear on the bottle body after individual bottles are formed.
3. The glass bottle initial mold and molding material are poor, the density is not enough, and the oxidation is too fast after high temperature, forming small pits on the surface of the mold, resulting in an unsmooth surface of the glass bottle after molding.
4. The poor quality of the glass bottle mold oil will make the mold not lubricated enough, the dripping speed will be reduced, and the material type will change too quickly.
5. The design of the initial mold is unreasonable, the mold cavity is large or small, and after the gob enters the forming mold, it is blown and spreads unevenly, which will cause spots on the glass bottle body. The temperature of the initial mold and the molding temperature of the glass bottle is not coordinated, and it is easy to create cold spots on the bottle body, which directly affects the smoothness.
7. The glass feed liquid in the kiln is not clean or the feed temperature is uneven, which will also cause bubbles, small particles and small hemp billets in the output glass bottles.
8. If the machine speed is too fast or too slow, the glass bottle body will be uneven, and the thickness of the bottle wall will be different, resulting in mottled.
