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. After positive blowing, the crease expands and widens, creating a crease in the body of the glass bottle.
2. The shear marks of the partial feeder are too large, and some glass bottles have shear marks on the bottle body after molding.
3. The initial mold and molding material of the glass bottle are poor, the density is not enough, the oxidation is rapid after high temperature, and tiny pits are formed on the surface of the mold, resulting in an unsmooth surface of the glass bottle after molding.
4. The design of the initial mold is unreasonable, the mold cavity is large or small, and after the gob enters the mold, it is blown and spreads unevenly, which will cause spots on the glass bottle.
5. The machine dripping speed is not uniform, and the improper adjustment of the air nozzle will make the glass bottle initial mold and mold temperature uncoordinated, and it is easy to create cold spots on the glass bottle body, which directly affects the smoothness.
