The market share of multi-functional automatic pet blow […]
The market share of multi-functional automatic pet blow molding machine is getting higher and higher, but at the same time, the failure rate of the blow molding machine has also increased. I often ask customers about bottle explosion during the blow molding process. Follow Taizhou DianYa Intelligent Equipment Co., Ltd to know the reason.
Q: The preform is heated too high and the preform turns white
Solution: The setting parameters of each automatic pet bottle blowing machine manufacturer are different. You need to consult the purchasing manufacturer to set the heating temperature of each lamp tube and adjust it to the appropriate temperature. Generally, the preform turning white is mainly caused by excessive heating, and it is appropriately reduced. Each tube temperature.
Q: The blow molding machine is not set for pre-blowing or the pre-blowing time is too short
Solution: Adjust the pre-blowing parameters of the bottle blowing machine during the setting process, and adjust the pre-blowing time of the bottle blowing machine according to the manufacturer's technical parameters.
Q: Blowing machine high pressure is too high
Solution: If the high pressure is set too high, it is most likely to cause the bottle to burst during the bottle blowing process. After the preform is stretched by the stretching rod, the high pressure blows the bottle quickly, and the excessive pressure directly causes the bottle to burst.
Q: The mold is not in place during the mold clamping process
Solution: The overwhelming majority of bottle bursts during mold clamping is due to the incorrect clamping position, which causes the bottle clamp to break. Most of this problem is caused by the manufacturer not adjusting the installation mold in place, and it is necessary to re-install the mold clamping mold correctly.
Q: Blower cylinder malfunction
If all the bottles in each mold cavity are burst bottles, and one cavity is exploded, most of them are because the cylinder of the bottle blowing machine is broken, and a new cylinder needs to be updated.
