Missing parameter records make problem tracing and process optimization difficult
Problem Phenomenon
Missing parameter records make problem tracing and process optimization difficult
Cause Analysis
Key parameters (temperature/pressure/speed/time) records incomplete
Parameter changes not recorded, quality fluctuations cannot be traced
Large parameter differences between batches, no standardization
Abnormal parameters not recorded in time
Lack of correlation analysis between process parameters and quality
Solution
Establish a complete parameter recording system
Record all key parameter changes
Standardize process parameters of each batch
Record abnormal parameters in time
Establish a correlation database between parameters and quality
Key Takeaway
Process records need to be complete and standardized
