The bottle blowing machine is mainly used for blowing bottle preforms. Many users have reported that the bottom of the bottles produced by the bottle blowing machine is not formed, which is caused by various reasons. The editor will share with you the reasons and solutions for the bottle bottom not forming.

1. Reason for bottle bottom heating

At present, most automatic PET blow molding machines use infrared tube heating. The heating box is divided into multiple independent areas and the temperature is controlled separately. Insufficient or too low heating of the bottle bottom can cause the blow molding bottle bottom to not form properly.

Solution: Adjust to the appropriate bottom heating temperature for the bottle. For detailed temperature adjustment, please consult the after-sales service of the bottle blowing machine manufacturer.

2. Reason for stretching

Eccentricity of the stretching rod or too short of the stretching rod can cause deformation of the bottle bottom or insufficient force, which can result in the bottle bottom not forming properly.

Solution: Adjust the position and length of the stretching rod

3. Reason for blowing air

Insufficient high-pressure blowing, adjust the blowing pressure

4. Reason for bottle bottom mold

The gap between the bottom mold and the preform mold can cause air leakage or incorrect height adjustment of the bottom mold, which can result in the bottom of the bottle not forming properly.

The above is the solution to the problem of the bottle bottom not forming when blown out by the bottle blowing machine. For new users, they are not yet familiar with the performance and convenience of the bottle blowing machine. It is recommended to consult the after-sales master of the bottle blowing machine equipment manufacturer before operation.
