Common Mistakes to Avoid
Weak Magnetic Strength
Key Consideration: Magnets may weaken over time or fail to hold heavy items.
Tip: Specify magnet grade (N52 recommended) and test with full product weight.
Incorrect Magnet Placement
Key Consideration: Improperly placed magnets cause misalignment or weak closure.
Tip: Request a pre-production sample to verify alignment before bulk run.
Surface Paper Delamination
Key Consideration: Cardstock with surface paper may delaminate at seams over time.
Tip: Specify edge-sealed finishing for durability.
Storage in Humid Conditions
Key Consideration: Humidity can weaken chipboard and affect magnet performance.
Tip: Store in dry environment, consider moisture-resistant coating.
