1. Incorrect troubleshooting sequence
Skipping basic visual inspections and alarm code checks to immediately dismantle core components wastes time and risks disrupting the equipment's original state, potentially turning minor faults into major issues.
2. Blindly replacing parts
Replacing components like sensors or motors without verifying parameters fails to pinpoint the actual fault, wastes parts, and may even introduce new installation errors.
3. Ignoring process parameter verification
Focusing solely on mechanical structures while overlooking drifts in process parameters-such as tension taper, blade clearance, and web-guiding thresholds-leads to persistent issues like burrs or uneven winding, despite repeated adjustments.
4. Skipping test cuts
Proceeding directly to full-speed mass production after troubleshooting-without performing low-speed no-load runs or small-sample test cuts-risks overlooking latent precision errors, potentially resulting in the scrapping of entire batches of finished aluminum foil.
5. Failure to document and track issues
Neglecting to record the symptoms, causes, and solutions after resolving a fault allows recurring issues to persist and prevents the creation of an equipment-specific troubleshooting knowledge base.
