In the production process of glass wine bottles, irregular manufacturing processes or other external factors will lead to defects in glass wine bottles. Unsmooth surface of glass wine bottles is one of the more common defects. Then, the main cause of unclean glass wine bottles is. What are the factors?
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 of the upper feeder are too large, and the scissors scars appear on the bottle body after individual bottles are formed.
3. The initial mold and molding material of the glass wine bottle 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 wine bottle after molding.
4. The poor quality of the mold oil of the glass wine bottle 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 of the glass wine bottle is unreasonable, and the mold cavity is large or small. After the material drops into the molding mold, it is blown up and spreads unevenly, which will cause spots on the bottle body of the glass wine bottle.
6. The machine dripping speed is uneven, and the improper adjustment of the air nozzle will make the glass bottle initial mold and mold temperature uncoordinated, and it is easy to create cold spots on the glass bottle body, which directly affects the finish.
7. The glass material liquid in the kiln is not clean or the material temperature is uneven, which will also cause bubbles, small particles and small hemp billets in the output glass wine bottle.
8. If the machine speed is too fast or slow, the glass bottle body will be uneven, and the thickness of the bottle wall will be different, resulting in mottled.
