Common bad phenomena of bottle blowing machines, and the reasons for these phenomena, and how to deal with them.
1. Poor shape of the bottle:
a: The temperature of the entire preform is too low. In this case, the temperature of the preform is increased.
b: The air outlet of the blow molding cavity is poor. Check if the air outlet is blocked.
c: The pressure of the blowing air is not enough. Check the pressure of the blowing air
d: The capacity of blowing air is not enough. Check the blowing air supply circuit.
2. There are wrinkles on the surface of the bottle:
a: The time of one blow molding is too late, and the temperature of the preform relative to this part is too low. Adjust the blow molding timer once.
b: The temperature of the preform is not uniform. Please increase the temperature of this part of the heater.
c: The thickness of the preform is uneven. Check the preform.
3. The preform is bent and deformed when the bottle blowing machine is heated:
a: The rotation of the preform during heating is not correct. Check whether the reflector, etc. collide.
b: Local overheating of the preform. Adjust the output of the heater section.
c: The preform is too hot. Check the preform.
