Packaging & Transportation
· Magnets are first stacked and separated using plastic or cardboard spacers to prevent direct contact and chipping.
· The stacked magnets are securely bound with shrink film or wrapping film to ensure stability.
· Each bundle is wrapped with protective materials such as bubble wrap or foam to absorb impact.
· Wrapped magnets are placed into a strong inner carton with additional cushioning.
· The carton is sealed and labeled, including product information and handling marks.
· For export shipments, cartons are packed into outer cartons or wooden cases as required.

FAQ
Q1. What factors should be considered when selecting a magnet grade beyond Br values?
Grade selection should prioritize intrinsic coercivity (Hcj), operating temperature, and safety margin against demagnetization. High Br alone does not guarantee performance stability, especially in compact magnetic circuits or elevated-temperature environments.
Q2. Can NdFeB magnets be used in dynamic or high-vibration applications?
Yes, but mechanical reinforcement and proper bonding are essential. NdFeB magnets are brittle, and vibration can cause cracking or coating failure. Structural support, adhesive selection, and shock-absorbing design significantly improve service life.
Q3. How does magnetization direction influence assembly and performance?
Incorrect magnetization orientation can reduce effective magnetic flux and complicate assembly. For complex geometries, multi-pole or custom magnetization must be evaluated during the design stage to ensure functional consistency and manufacturability.
