[China Glass Net] 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 to form a fold. After the blow is blown, the wrinkles spread and enlarge, forming wrinkles in the glass bottle body. 2. The upper feeder scissors are too large, and the individual glass bottles are formed after the scissors appear on the bottle. 3. The initial mold and molding material of the glass bottle are poor, the density is not enough, and the oxidation is too fast after high temperature, forming fine pits on the surface of the mold, resulting in the surface of the glass bottle being unclean after molding. 4. The poor quality of the glass bottle mold oil will make the mold lubrication insufficient, the dropping speed will decrease, and the material type will change too fast. 5. The design of the initial mold is unreasonable. The cavity is large or small. After the material is dropped into the mold, the diffusion is uneven, which will cause spots on the glass bottle. The machine will not evenly spread the speed of the machine. The initial mold and mold temperature of the glass bottle are not coordinated, and it is easy to produce cold spots in the bottle body, which directly affects the smoothness. 7. The glass material in the kiln is not clean or the temperature is not uniform, which will cause bubbles, small particles and small hemp blanks in the produced glass bottles. 8. If the speed of the line machine is too fast or slow, the glass bottle will be uneven, and the bottle wall will be thin and thick, resulting in spots.
