Which parts of a packaging machine most commonly need replacement?
• Heat-seal jaws and PTFE tape: replace when seals whiten or leak, every 1-3 months.
• Cutting and serrated knives: change on ragged cuts or film stringing, high-wear items.
• Metering screw/cup seals: replace when dosing deviates over ±2% or powder leaks.
• Conveyor and timing belts: change on tracking drift or tension loss, every 6-12 months.
• Cylinder seals and solenoid valves: replace on slow action or air leak, affecting cycle time and seal pressure.
