What factors affect the finish of glass wine bottles?
Based on my many years of work experience, I summarize the following eight factors that affect the finish of glass wine bottles.
1. The scissor mark of the upper feeding machine is too large, and the scissor mark appears on the body of some bottles after forming.
2. 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.
3. The initial mold and molding material of the glass wine bottle 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 molded glass wine bottle being not smooth.
4. 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.
5. The poor quality of glass wine bottle mold oil will cause insufficient lubrication of the mold, slow down the dripping speed, and change the material shape too quickly.
7. 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.
8. The design of the initial mold is unreasonable, the cavity is large or small, and after the material drips into the forming mold, it is blown and diffused unevenly, which will cause spots on the glass bottle body. The uncoordinated temperature between the initial mold and the mold forming of the glass bottle will easily cause cold spots on the glass bottle body, which will directly affect the finish.
