What are the reasons for the reproduction of glass bottles | QLT Glass

    In the production of glass bottles, non-standard manufacturing technology or other external factors will cause defects in the bottles, and the surface of the bottles is not smooth and clean, one of the common defects.

  1.When the glass blank falls into the initial mold, it cannot accurately enter the initial mold, and the mold wall is too large, forming folds. After blowing, the wrinkles are diffused and magnified, forming folds in the glass bottle body.

2.The scissor mark of the upper feeding machine is too large, and the scissor scar appears in the bottle body after the forming of individual bottles.

3.The glass bottle initial mold and molding material is poor, the density is not enough, the oxidation is too fast after high temperature, the concave points formed on the surface of the mold, resulting in the surface of the glass bottle after molding is not smooth and clean.

4.The oil difference of the glass bottle mold will make the mold insufficient, the drop rate and the material type change too fast.

5.The initial mold design is not reasonable, the mold cavity is large or small, the material drops into the molding mold, is blowing up the diffusion is not uniform, will make the glass bottle body point.

6.The machine drops the material speed is not uniform, the air nozzle is not appropriate will make the glass bottle initial mold and mold temperature is not coordinated, easy to make cold in the glass bottle body, directly affect the finish.

7.The glass liquid in the kiln is not clean or the material temperature is not uniform, which will also make the produced glass bottle appear bubbles, small particles and small hemp billet.

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 patterns.
