1. Check and control the proportion of raw materials, mix evenly.

2. Check whether the temperature control of the composite bubble film machine is good, whether the heating appliance is in good condition, and pay attention to timely adjusting the heating temperature of each point within the target range.

3. Observe and adjust the uniformity of film thickness, and the folding diameter meets the standard.

4. Check whether there are impurities on the raw materials of the composite bubble film machine, especially the iron mixed with magnets.

5. Regularly check the temperature rise of the motor running the composite bubble film machine and the transmission of the bubble film machine.

6. Check the traction speed and control film thickness.

7. Check the pressure of the storage tank of the composite bubble film machine, not too high, but there should be a backup pressure.

8. Check the lubrication of the reducer and the air compressor cylinder. Therefore, when operating the bubble film machine, these details must be done to ensure its good performance.
