How should I establish a maintenance schedule for a packaging machine?
• Classify by critical parts: inspect high-wear heat-seal jaws and cutters at 500h, lubricate bearings at 2000h.
• Set thresholds from film tension, sealing pressure and cycle time; trigger maintenance if deviation exceeds ±10%.
• Daily clean photo-eyes and formers; weekly check heat-seal temperature and belt tension; monthly verify dosing accuracy.
• Use PLC/HMI alarms and OEE data; shorten intervals for components causing over 2% downtime.
• Start from OEM manual intervals, adjust for dust, humidity and 3-shift operation, then document and verify.
