So where do these defects come from, let’s find out!

1.      When the glass blank falls into the initial mold, it cannot enter the initial mold accurately, and the excessive friction between the blank and the mold wall, resulting in folds. After blowing, the wrinkles spread and enlarge, forming folds in the glass bottle body.

2.       Some feeding machine cutting scar is too large, some glass bottle after molding cutting scar appeared in the bottle body.

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

4.       Poor quality of glass bottle mold oil will cause the low mold lubrication, the dropping speed will be reduced accordingly, lead to the material change too fast.  

5.       The initial mold design is unreasonable, the mold cavity size is uneven, after the material drops into the forming mold, the blowing diffusion is unevenly spread, causing spots on the glass bottle.

6.      The uneven drip speed of the machine and the Improper adjustment of the nozzle will make the glass bottle initial mold and finished mold temperature is not coordinated, easy to cause cold spots in the glass bottle body, directly affect the finish. 

7.       If the glass material liquid in the kiln is not clean or the material temperature is different, small particles will also appear in the glass bottles.
