Function test (start → run → stop) No abnormal noise, no vibration, stable operation
Safety check guards, interlocks, emergency stop Emergency stop response time is ‌≤ 0.5 seconds, and the protective shield remains intact.
Accuracy calibration size, seal position, cutting Dimensional deviation ≤ +1mm, sealing deviation ≤ 0.5mm
Seal integrity test continuous running with real products Peel strength ≥30N/15mm, no air leakage
Load test continuous running with real products Pass rate ≥99.8%
Noise & vibration test Noise & vibration during running Meets industry standards
