Packaging Process
5.1 Pre-Packaging Preparation
Before packaging, all magnets undergo a standardized preparation and verification process:
√ Specification verification
Confirmation of magnet grade, dimensions, tolerances, coating type, and magnetization status
√ Appearance and quantity inspection
Visual inspection for cracks, chipping, coating defects, and surface damage
Verification of quantity per batch and per order
√ Magnetization status confirmation
Identification of magnetized or un-magnetized products to determine appropriate shielding measures
5.2 Individual Protection and Inner Packaging
To prevent direct contact and uncontrolled magnetic attraction, magnets are protected at the individual or small-group level.
Single-Piece Protection
Separation using PE bags, bubble wrap, or paper spacers
Prevention of direct magnet-to-magnet contact
Additional protection for thin, small, or irregular-shaped magnets
Magnetic Shielding Measures
Use of steel plates or alternating magnetic orientation
Reduction of external magnetic field intensity
Preparation for magnetic inspection when required for air shipment
