Appearance & Dimensional Inspection
● Surface Condition Evaluation
Under controlled illumination conditions, qualified quality inspectors examine the magnets for surface defects such as fractures, edge damage, internal impurities, porosity, or signs of corrosion.
● Magnetic Output Uniformity Verification
Magnetic flux is measured using calibrated flux measurement instruments or Hall sensor systems to confirm consistency and stability of magnetic performance across production batches for reliable end-use operation.
Packaging & Transportation
● Finished magnets are inspected and then arranged in aligned stacks.
● Separator sheets are inserted between magnets to prevent surface damage.
● The stacks are wrapped and fixed to maintain magnetic stability.
● Products are packed in cartons with customized cushioning solutions.
● Final packages are labeled and moved to the finished goods warehouse.
Handling and Application Guidelines
Mechanical protection
NdFeB magnets exhibit high hardness but limited toughness. Sudden impact or mechanical shock may result in cracking or edge damage and should be avoided.
01
Safe separation method
Due to strong attractive forces, magnets should be separated by lateral sliding. Direct pulling or prying can cause injury or magnet breakage.
02
Correct orientation during assembly
Polarity and magnetization direction must be verified prior to installation to ensure proper system functionality.
03
Environmental control
Exposure to humidity, corrosive chemicals, or aggressive atmospheres may accelerate corrosion. Storage and operation in dry, neutral environments are recommended.
04
Magnetic field influence
Strong magnetic fields may interfere with electronic storage media, precision electronics, and implanted medical devices. Adequate separation distance should be maintained.
05
Custom Manufacturing and Technical Support
Application-specific geometry
Magnet dimensions and geometries can be engineered to match customer designs and assembly constraints.
Surface protection options
Multiple coating systems and configurations are available to improve corrosion resistance and durability under different service conditions.
Magnetic performance configuration
Magnetization direction, pole arrangement, and magnetic output can be adjusted to meet functional requirements.
Marking and traceability services
Permanent laser marking is available for identification, batch tracking, or branding purposes.
Frequently Asked Questions:
Q1. What causes chipping or cracking in NdFeB magnets?
Answer:NdFeB magnets are hard and brittle. Chipping or cracking can be caused by:
Direct magnet-to-magnet impact
Insufficient packaging protection
Improper handling during assembly
Using spacers and proper packaging significantly reduces this risk.
Q2. How does coating thickness affect magnetic performance?
Answer:Coating thickness slightly reduces the effective magnetic gap, which may cause a minor decrease in surface field.
However, the impact is usually negligible compared to the benefits of corrosion protection.
Q3. What is irreversible demagnetization?
Answer:Irreversible demagnetization occurs when a magnet is exposed to excessive heat, reverse magnetic fields, or mechanical shock, causing permanent loss of magnetic performance.
Selecting the correct temperature grade and magnet design helps prevent this issue.
