Common blow molding machine quality problems and solutions

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.
