Now borosilicate double wall glass drinking cup is a product that we often see in our daily lives. It can be said that compared with other glass products, borosilicate double wall glass drinking cup has some advantages that other products cannot match, but in production In the process, the smoothness of borosilicate double wall glass drinking cup will be bad, so today we will take a look at which factors will affect the smoothness of borosilicate double wall glass drinking cup?

1. When the borosilicate double wall glass drinking cup falls into the preliminary mold, the blank cannot accurately enter the preliminary mold, and it rubs against the mold wall too much to form creases. After blowing, the wrinkles spread and enlarge, and form in the borosilicate double wall glass drinking cup. Folds.

2. The scissor marks of the upper feeder are too large, and the scissor marks appear on the borosilicate double wall glass drinking cup after some bottles are formed.

3. The material of the borosilicate double wall glass drinking cup is poor, and the density is not enough. After high temperature, it oxidizes too fast, forming small pits on the surface of the mold, which causes the surface of the formed borosilicate double wall glass drinking cup to be dirty.

4. Poor quality of borosilicate double wall glass drinking cup mold oil will cause insufficient mold lubrication, lower dripping speed, and rapid change of material type.

5. The design of the initial mold is unreasonable, the cavity is large or small, and the material droplets are blown and diffused unevenly after entering the molding mold, causing spots on the body of the borosilicate double wall glass drinking cup.

6. ​​The dripping speed of the machine is uneven, and the improper adjustment of the nozzle will cause the temperature of the borosilicate double wall glass drinking cup to be uncoordinated, and it is easy to create cold spots on the borosilicate double wall glass drinking cup, which directly affects the finish.

7. Unclean glass liquid or uneven material temperature in the kiln can also cause bubbles, small particles, and hemp billets to appear in the produced borosilicate double wall glass drinking cup.

8. If the speed of the parallel machine is too fast or slow, the body of the borosilicate double wall glass drinking cup will be uneven, and the bottle wall will be of different thickness, causing mottling.
