1.The preform is heated too high and the preform becomes 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 a suitable temperature. Generally, the whitening of the preform is mainly caused by excessive heating. Please reduce each lamp appropriately. Tube temperature.
2.The plastic blowing 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 bottle blowing machine, and adjust the pre-blowing time of the bottle blowing machine according to the manufacturer's technical parameters.
3.Blowing machine high pressure
Solution: If the high pressure is set too high, it is most likely to cause the bottle to burst during the blowing process. After the stretch rod stretches the preform, the high pressure blows the bottle quickly, and the excessive pressure directly causes the preform to burst.
4.The mold is not in place during the clamping process
Solution: The majority of bottle bursts in the mold clamping process are caused by the incorrect clamping position of the bottle. This problem is mostly caused by the manufacturer's failure to adjust the mold in place, and the clamping mold needs to be reinstalled correctly.
5.Bottle blowing machine cylinder failure
If all the bottles in each mold cavity are burst bottles, and one cavity bursts out of one cavity, it is mostly because the cylinder of the blowing machine is broken, and a new cylinder needs to be updated.
