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 shear marks of the feeder are too large, and the bottle body appears shear marks after individual bottles are formed.
3. The initial mold of the glass bottle and the molding material are poor, the density is not enough, the oxidation is too fast after high temperature, and the surface of the mold forms small pits, resulting in the bottle after the glass surface is not smooth.
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. Friction with the mold wall. Sometimes in the production of wine bottles, when the glass blank falls into the preliminary mold, it cannot enter the preliminary mold accurately, and rubs against the mold wall to form creases, and the surface wrinkles will spread after blowing. , it is easy to cause wrinkles on the bottle body of the wine bottle, which seriously affects its smoothness.
6. The initial mold design is unreasonable. Sometimes when we are producing glass bottles, due to the unreasonable design of the initial mold, there will be problems during use, and problems will occur if the mold cavity is too large or too small. In this way, after the gob falls into the formingmod, t is blown up and spreads unevenly, which will cause spots on the bottle body of the glass bottle.
7. The glass feed liquid in the furnace is not clean or the temperature of the material is uneven, which will also cause bubbles, small particles and small hemp billets in the output glass bottle.
