After the glass bottle is produced and formed, sometimes there will be many spots, wrinkles, bubble scratches, etc. on the bottle body, which are mostly caused by 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, forming a crease.
2. The shears of the feeder are too large, and the shears appear on the bottle body after individual glass bottles are formed.
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 small pits on the surface of the mold, causing the surface of the glass bottle to be uneven after molding.
4. The poor quality of the glass bottle mold oil will make the mold not lubricated enough, the dripping speed will be reduced, and the material type will change too quickly.
5. The initial mold design is unreasonable, the mold cavity is large or small, the gob is blown up after entering the molding mold, and the spread is uneven, which will cause spots on the glass bottle
6. The dripping speed of the machine is not uniform, and the improper adjustment of the air nozzle will make the initial mold and mold temperature of the glass bottle uncoordinated, and it is easy to produce cold spots on the glass bottle, which directly affects the finish.
7. The glass feed liquid in the kiln is not clean or the feeding temperature is uneven, which will also cause bubbles, small particles and small hemp billets to appear in the output glass bottle.
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 mottled.
