What are the factors that affect the smoothness of glass bottles? | QLT Glass

I believe that everyone is familiar with glass bottles, and we can often see them in our daily life. Some glass bottles are smooth and crystal clear at first sight, while some appear to have creases or dirt. Today, we will tell you about the factors that endanger the smoothness of glass bottles.
What are the factors that affect the smoothness of glass bottles？

1. When the glass blank falls into the parison mold, it can not enter into the parison mold accurately. The friction between the glass blank and the mold wall is too large, resulting in wrinkles. After the positive air blowing inspection, the wrinkles spread outward and become larger, resulting in wrinkles on the glass bottle body.
2. The shear scar of the upper feeder is too large, resulting in the appearance of the shear scar on the bottle body after some glass bottles are formed.
3. The initial mold and molding materials of the glass bottle are poor, the relative density is insufficient, and the air oxidation is too fast after high temperature, resulting in small pits on the surface of the mold, resulting in the unsmooth surface of the glass bottle after forming.
4. Too low oil quality of the glass bottle mold will lead to insufficient wetting of the mold, reduced drop rate and too fast material type change.

5. The design concept of the initial mold is not scientific. The mold core is either large or small. After the material drips into the forming mold, the positive blowing and outward diffusion are not symmetrical, which will cause the glass bottle body to appear black spots
6. The uneven dropping rate of the equipment and the improper adjustment of the air nozzle will make the initial mold and molding temperature of the glass bottle incompatible, and it is very easy to produce cold spots on the glass bottle body, thus affecting the smoothness.
7. The dirty liquid or uneven temperature of laminated glass in the industrial furnace will also cause the production rate glass bottle to appear bubbles, small particles and small hemp.
8. If the speed of the team is too fast or too slow, the glass bottle body is uneven, and the thickness of the bottle wall is different, causing spots.
That is to say, the eight reasons why the smoothness of glass bottles is harmed by the net editor. We hope that the glass bottle factory will pay more attention to the whole process of production and manufacturing in the future.
