What Factors in The Production Of Glass Bottles Destroy The Finish Of The Bottle Body?

1. When the glass blank falls into the initial mold, it cannot enter the initial mold accurately, and the friction with the mold wall is too large, forming creases. After blowing, the creases spread and enlarge, forming wrinkles on the glass bottle body.
2. The scissor mark of the upper feeding machine is too large, and the scissor mark appears on the body of some glass bottles after molding.
3. The material of the glass bottle initial mold and molding is 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 glass bottle being not smooth after molding.
4. The poor quality of glass bottle mold oil will cause insufficient lubrication of the mold, slow down the dripping speed of lubricating oil, and change the material shape too quickly.
5. The initial mold design is unreasonable, the mold cavity is large or small, and after the material drops into the forming mold, it is blown and diffused unevenly, which will cause spots on the body of the glass bottle.
6. The dropping speed of the machine is not uniform, and the improper adjustment of the tuyere will cause the temperature of the glass bottle initial mold and mold forming to be uncoordinated, and it is easy to create cold spots on the glass bottle body, which directly affects the finish.
7. If the glass material liquid in the kiln is not clean or the temperature of the material is not uniform, it will also cause bubbles, small particles, and small flakes to appear in the output glass bottles.
8. If the machine speed is too fast or slow, the glass bottle body will be uneven, and the bottle wall thickness will vary, resulting in mottling.
The above are the factors that easily cause or damage the smoothness of the bottle body during the production of glass bottles.
