LLDPE film digital twin optimization
Problem Phenomenon
Trial machine tuning cost is high; after introducing digital twin, the trial cost dropped 70%.
Cause Analysis
The LLDPE process parameter space is complex, and the traditional trial-and-error method is costly; the digital twin rehearses parameter combinations in virtual space.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Solution
①Evaluate digital twin tools; ②establish a process database; ③verify virtually before running on the machine; ④continuously calibrate the model.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Key Takeaway
Digital tools are a new path for complex process optimization; data accumulation is the premise for realizing value.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
