Mass Production Of Pet Bottle Preform

The advent of blow molding machines has greatly facilitated our daily life. For every Pet Preform manufacturer, the daily maintenance and inspection of blow molding machines is very important:

1 no feed level added; several cases need to be checked;

Did you not expect the hopper, if it is: need to hurry

No: Please check if the hoist control contactor is energized. If it is energized, check that the motor is energized and loaded because the preform (embryo) may get stuck. The easiest way to belt is to help improve manually.

If the control contactor of the hoist is not energized, check that the preform is detecting that the electric eye is not on the same line as the reflector.

2 feeding the old card feeding tray: This situation is a headache. From an empirical point of view, this phenomenon is relatively small if the length of the preform (embryo) is relatively long and the cutting weight is large.

3 After the bottle is blown out, it cannot be taken out of the mold.

First, the mold should be opened and the mold should be opened and closed manually. If it is normal, please run in the dry running state, if it is normal.

Please check the exhaust time setting. If the exhaust is set up properly and it will fail every time you blow the bottle, you can judge the problem with the exhaust valve. Please open the exhaust valve to check the spring and seal. There is also a phenomenon in which the exhaust sound is relatively large or the sound is not good.

If you are experiencing a large number of Pet Bottle Preform, and occasionally come over this mold can not open the mold, please check if there is a screw inside the lock pin, in addition, please check if the clamping force is too large, if it is too large, it should be re-standard Adjustment.
