The bottle blowing machine is mainly used to blow the bottle preforms. Many users feedback that the bottom of the bottle from the bottle blowing machine is not formed. There are many reasons for the bottom of the bottle. Causes and solutions.
Causes of heating at the bottom of the bottle
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. If the bottom heating temperature is not enough or the heating is too low, it will cause the bottom of the blowing bottle to be unformed.
Solution: Adjust to the appropriate heating temperature at the bottom of the bottle. For detailed temperature adjustment, please consult the after-sales service of the pet blow molding machine manufacturer.
Stretching reason
Eccentric or too short stretch rods can cause the bottom of the bottle to be deformed or the force is too small, which can cause the bottom of the bottle to be unformed.
Solution: Adjust the position and length of the stretch rod.
Reason for blowing
Insufficient high-pressure blowing, adjust the blowing pressure.
Bottle bottom mold reason
The gap between the bottom mold and the closed mold of the preform, the occurrence of air leakage or the incorrect height adjustment position of the bottom mold can cause the bottom of the bottle to be unformed.
