At present, the market share of the multifunctional blow molding machine is getting higher and higher, but at the same time, the failure rate of the blow molding machine has also increased. For this reason, please come to the bottle blowing machine master with many years of experience and maintenance to share with you the various reasons and solutions for bottle explosion when blowing by the multi-functional bottle blowing machine.

The preform is heated too high and the preform turns white

Solution: The setting parameters of each bottle blowing machine manufacturer are different. You need to consult the purchaser to set the heating temperature of each lamp and adjust it to an appropriate temperature. Generally, the whitening of the preform is mainly caused by excessive heating. Lower each lamp appropriately. tube temperature.

The blow molding machine is not set to pre-blowing or the pre-blowing time is too short

Solution: Adjust the pre-blowing parameters during the setting process of the blowing machine, and adjust the pre-blowing time of the blowing machine according to the technical parameters of the manufacturer.

The high pressure of the blow molding machine is too high

Solution: The high pressure setting is too high, which is most likely to cause the bottle to burst during the blowing process of the preform. After the stretch rod stretches the preform, the high pressure blows the bottle rapidly, and the excessive pressure directly causes the bottle to burst.

The mold is not closed in place during the clamping process

Solution: The vast majority of bottle bursts in the mold clamping process are caused by the wrong clamping position, which causes the bottle to be broken. Most of this problem is caused by the manufacturer's failure to adjust the installation mold in place, and the clamping mold needs to be re-installed correctly.

Cylinder failure of blow molding machine

If all the bottles in each mold cavity are burst bottles, and one cavity bursts one cavity, most of them are because the cylinder of the blow molding machine is broken, and a new cylinder needs to be replaced.
