We use glass, a high-grade packaging material, to improve the grade of the product, further enhance the brand awareness, and make the product stand out from many competitors. If you can’t source high-quality glass bottles, you will make your own products labeled as cheap and low-quality. If we want to purchase high-quality glass bottles, we first need to know what kind of glass bottles are inferior, and then we can know how to distinguish the quality of glass wine bottles. Let’s learn about several common qualities of glass bottles. question.
1. Bottle folds
The glass frit is too soft or too hard, which will cause the glass blank to not accurately enter the initial mold when it falls into the initial mold, and then the friction with the mold wall is too large to form creases. folds.
2. Knife scar
The scissors marks of the upper feeder are too large, and the scissors scars appear on the bottle body after individual glass bottles are formed.
3. Concave point
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, resulting in an unsmooth surface of the glass bottle after molding.
4. Deformation
The poor quality of glass bottle mold oil will make the mold not lubricated enough, the dripping speed will be reduced, the material type will change too fast, and the bottle structure will change.
5. Spots
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 up and spreads unevenly, which will cause spots on the glass bottle.
6. No gloss
Uneven dripping speed of the machine and 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.
7. Bubbles
The glass feed liquid in the kiln 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 bottles.
8. The thickness of the bottle wall varies
If the machine speed is too fast or slow, the glass bottle body will be uneven, the thickness of the bottle wall will be different, resulting in mottled.
