Eight common factors of bubbles and scratches in glass bottle production
1 When the glass material blank falls into the primary mold, it cannot enter the primary mold accurately, and the friction with the mold wall is too large. Efforts are made to promote the development of new materials to form wrinkles. After being blown, the wrinkles are diffused and enlarged, and the experts say that wrinkles are formed in the glass bottle body
2. The scissor scar of the feeding machine is too large, and the scissor scar appears on the bottle body after the molding of some glass bottles
3. The initial mold and molding materials of glass bottles 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 the surface of the molded glass bottles is not smooth
4. The poor quality of glass bottle mold oil will make the mold lubrication insufficient, the dropping speed will be reduced, and the material type will change too fast
5. The design of the initial mold is unreasonable, and the mold cavity is large or small. After the material drips into the forming mold, it is blowing up and diffusing unevenly, which will make the glass bottle body appear spots
6 Uneven dropping speed of the machine and improper adjustment of the air nozzle will make the initial mold and molding temperature of the glass bottle inconsistent, and it is easy to make small, messy and poor power battery enterprise spots everywhere before the cold in the glass bottle body, which will directly affect the smoothness
7. Unclean glass liquid or uneven temperature in the kiln will also cause bubbles, small particles and small flax billets in the output glass bottles. Glass bottle is a traditional beverage packaging container in China. Glass is also a kind of packaging material with a long history. In the case of many kinds of packaging materials entering the market, glass containers still occupy an important position in beverage packaging, which is inseparable from its packaging characteristics that cannot be replaced by other packaging materials
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 spots
