I. Pre-emptive Emergency Check (Complete within 5 minutes)
First, confirm that the RC lock status has not been abnormally released, and the temperature controller status bar still displays the "RC Hardware Locked" indicator.
Check the actual temperature of each hot runner section to confirm that it does not exceed the process safety range and there is no risk of material degradation or runner blockage.
Confirm that there are no new sources of enhanced interference in the vicinity, and that temperature sensing wires and connectors are not damaged or loose, ruling out external hardware faults.
II. Quick Parameter Verification (Complete within 10 minutes)
Enter the temperature controller's "Signal Filtering Settings" interface and confirm that the currently locked RC parameters are completely consistent with the reference file, with no drift deviation.
Quickly verify core performance: Target interference signal attenuation ≥20dB, RC total time constant ≤200ms, and temperature sensing signal delay not exceeding the standard.
Confirm that the temperature control curve is smooth, without jumps, overshoot, or oscillations, and that temperature fluctuation is ≤±0.5℃, meeting the current injection molding process requirements.
III. Production Restart Operation (Complete within 15 minutes)
Confirm that the temperature of all hot runner points reaches the process set value, maintain stable temperature for 5 minutes, and eliminate temperature gradient differences within the runner.
Perform 1-2 air-jet cleaning operations to remove residual melt from the runner, ensuring uniform discharge without impurities.
Start injection molding production. After the first product passes appearance, dimensional, and performance verification, normal mass production can resume.
IV. Closed-Loop Finishing Operation
After production starts, continuously monitor temperature data for 30 minutes to confirm that the RC lock-up state is stable and there are no abnormal parameter changes.
Enter the time and operating parameters of this restart operation into the process file and update subsequent RC calibration cycles accordingly.
