2019-10-24

       

     

The blow molding machine is mainly used for blowing bottles of preforms. Many users feedback that the bottom of the bottle from the blow molding machine is not formed, which causes more reasons for the bottom of the bottle. Xiaobian does not share the bottom of the bottle. Reasons for forming and solutions.




1, the reason for stretching




If the stretching rod is eccentric or the stretching rod is too short, the deformation of the bottom of the bottle or the excessive force may cause the bottom of the bottle to be unformed.




Solution: adjust the position and length of the stretching rod




2, the reason for the bottom of the bottle




At present, most of the blow molding machines use infrared lamp heating. The automatic feeding heating box is divided into multiple independent zones. The temperature is controlled separately. If the heating temperature of the bottom of the bottle is not enough or the heating is too low, the bottom of the bottle will not be formed.




Solution: adjust to the appropriate bottom heating temperature, detailed temperature adjustment can consult the manufacturer after sale.




3, the reason for the bottom of the mold




The gap between the bottom mold and the blank mold clamping, the air leakage or the height adjustment position of the bottom mold can cause the bottom of the bottle to not form environmentally friendly materials.




4, the reason for blowing




Insufficient high pressure blowing, adjust the blowing pressure.
