The bottle blowing machine is mainly used for blowing bottle preforms. During the bottle blowing process, it is inevitable that the blown bottle will not be qualified and the bottle bottom will not be formed. There are many reasons for the bottle bottom not being formed. Mag bottle blowing machine manufacturer Let me share with you the reasons and solutions for the bottle bottom not forming.
1. Reasons for heating the bottom of the bottle
At present, most automatic PET bottle blowing machines use infrared lamp heating. The heating box is divided into multiple independent areas, and the temperatures are controlled individually. Insufficient or too low heating temperature at the bottom of the bottle will cause the bottom of the bottle to be deformed.
Solution: Adjust to the appropriate bottle bottom heating temperature, while reducing the high-pressure blowing time and increasing the cooling time. For detailed temperature adjustment, please consult the after-sales service of the PET bottle blowing machine manufacturer.
2. Reasons for stretching
The stretch rod is off-center or too short. Deformation of the bottom of the bottle or excessive force can cause the bottom of the bottle to not be formed.
Solution: Adjust the position and length of the stretch rod
3. Reasons for blowing
Insufficient air blowing pressure or too short air blowing time will cause the bottle bottom to be stressed for too short a time and the bottle bottom will not be formed.
Solution: Adjust the blowing pressure and blowing time
4. Causes of bottle bottom mold
The gap between the bottle bottom mold and the bottle preform mold, air leakage or incorrect height adjustment position of the bottle bottom mold can cause the bottle bottom to be deformed.
