The solution for PET bottle blowing machine to blow out the unformed bottle bottom
The bottle blowing machine is mainly used to blow the bottle on the preform. Most users report that the bottom of the bottle is not formed, and there are many reasons for the bottom of the bottle. Yucheng bottle blowing machine manufacturers share the reasons and solutions for the unformed bottom of the bottle.
1. Reasons for heating at the bottom of the bottle
At present, most automatic pet blowing machines are heated by infrared lamps. The heating box is divided into several independent areas, and the temperature is independently controlled. If the temperature is not enough or the heating is too low, it will cause the bottom of the bottle to be unformed.
Solution: Adjust the bottom of the bottle to a suitable bottom heating temperature. For the specific temperature adjustment, please consult the after-sales service of the pet blow molding machine manufacturer.
2. Reasons for stretching
Because the stretch rod is eccentric or the stretch rod is too short, deformation of the bottom of the bottle or too small force can cause the bottom of the bottle to be unformed.
Solution: adjust the position and length of the stretch rod
3. Reasons for blowing
Insufficient high-pressure blowing, adjust blowing pressure
4. Reasons for the bottom mold
Air leakage in the gap between the bottom mold and the preform mold or the incorrect height adjustment position of the bottom mold will cause the bottom of the bottle to be unformed.
Summary: The above is a solution for the bottom of the bottle blown by the bottle blowing machine without forming. For new users, who are not familiar with the performance of the blow molding machine and other aspects, it is recommended to consult the after-sales master of the blow molding machine equipment manufacturer before operation, or consult the after-sales technical support of the Yucheng blow molding machine online, and we will answer online for you.
