LDPE Film Cooling System Contamination
Problem Phenomenon
Bubble cooling unevenness worsens; inspection finds dust accumulation and clogging in the air ring and air ducts.
Cause Analysis
Long-term operation of the cooling system accumulates dust and oil; local clogging makes air output uneven; workshops with poor environmental quality are more prone to this.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience.
Solution
①Regularly clean the air ring and air ducts; ②Check the filtering device; ③Improve the workshop environment; ④Monitor air volume uniformity.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Key Takeaway
Cooling system cleanliness directly affects bubble stability; including it in periodic maintenance can prevent problems before they occur.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
