Thermal cutting knives indeed pose multiple safety hazards in practical operation. For instance, if the blade breaks and gets stuck in the mold, it can cause equipment damage. Alternatively, if the heating function is not promptly shut off after an alarm is triggered, there's a risk of material buildup igniting. To address these hazards, MEPER blow molding has implemented solutions such as designing safety measures like a broken blade protection shutdown alarm and smoke detection for the equipment.
