Statistical Process Control


Statistical Process Control (SPC) Assures Process and Product Consistency and Continuous Learning


In addition to predicting quality problems, signals from control charts are powerful tools for predicting the need for maintenance. In the example below, the drop in oven temperature from 119°C to 105°C, as plotted on the control chart, which identified a PLC malfunction in the oven air recirculation system.




An effective process control plan combines the right balance of process and product parameters. Key parameters allow easy detection of special cause variation and their diagnosis.
