After the glass bottle is formed, sometimes the bottle body will have many spots of wrinkles, bubble scratches, etc., which will greatly affect the smoothness of the bottle body for the following reasons:
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 are diffused and enlarged, and wrinkles are formed in the glass bottle body.
2. The scissors of the upper feeder are too large. After the individual glass bottles are formed, the scissors will appear on the bottle.
3. The initial mold and the molding material of the glass bottle are poor, the density is not enough, and the oxidation is too fast after the high temperature, and fine pits are formed on the surface of the mold, which causes the surface of the glass bottle to be 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, and the cavity is large or small. After the material is dropped into the molding die, the diffusion is uneven, which will cause spots on the glass bottle. The speed of the machine is not uniform, and the adjustment of the air nozzle will be improper. 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 material temperature is not uniform, which will also cause bubbles, small particles and small hemp blanks in the produced glass bottles.
8. If the speed of the machine is too fast or slow, the glass bottle will be uneven, and the bottle wall will be thin and thick, resulting in spots.
