Solution to the problem of unformed bottle bottoms blown out by bottle blowing machines
The bottle blowing machine is mainly used to blow bottles on preforms. Most users report that the bottle bottom of the bottle blowing machine is not formed. There are many reasons for the unformed bottle bottom. Yucheng bottle blowing machine manufacturer shares with you the reasons and solutions for the unformed bottle bottom.
1. Reasons for bottle bottom heating
At present, most automatic pet bottle 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, the bottom of the blown bottle will not be formed.
Solution: Adjust the bottle bottom to the appropriate bottle bottom heating temperature. For specific temperature adjustment, please consult the pet bottle blowing machine manufacturer after-sales.

Common technical problems of PET bottle blowing machine
The blow molding process is a bidirectional stretching process, during which the PET chain is bidirectionally extended, oriented and arranged, thereby increasing the mechanical properties of the bottle wall, improving the tensile, tensile and impact strengths, and having good air tightness. Although stretching helps to improve strength, it should not be overstretched. The stretch-blow ratio should be well controlled; the radial ratio should not exceed 3.5-4.2, and the axial ratio should not exceed 2.8-3.1. The wall thickness of the preform should not exceed 4.5mm.
