Appearance & Dimensional Inspection
- Visual Inspection: Under standardized lighting, trained QC staff check for cracks, chipping, inclusions, pores, or oxidation.
Image Measurement System: High-definition cameras and algorithms conduct non-contact 2D measurements, especially for complex or irregular shapes, ensuring efficiency and objectivity in mass production.
Automated Intelligent Inspection: High-speed cameras with AI algorithms detect and reject defects (e.g., cracks, scratches, discoloration) and dimensional anomalies, improving yield and reducing human error.
Usage Precautions
To ensure safe handling and maintain optimal magnet performance:
Handle with care:
Magnets are brittle; avoid impact, collision, or dropping.
01
Prevent pinching injuries:
Separate magnets by sliding them apart rather than pulling or prying.
02
Verify polarity before installation:
Incorrect alignment may cause assembly failure or reduced performance.
03
Avoid corrosive environments:
Store magnets in dry, neutral conditions-keep away from moisture, acids, and alkalines.
04
Keep away from sensitive equipment:
Strong magnetic fields may interfere with hard drives, IC cards, pacemakers, and similar electronics.
etc.

FAQ
Q1. What causes performance variation between production batches?
Answer:Batch variation can result from differences in:
Raw material composition
Sintering density and grain orientation
Magnetization saturation level
Coating thickness and uniformity
Strict process control and batch traceability are essential to maintain consistency.
Q2. Why is pull force not a reliable indicator of overall magnetic performance?
Answer:Pull force depends heavily on test conditions such as surface flatness, steel plate material, air gap, and alignment. It reflects system interaction, not intrinsic material properties like Br or Hcj.
Q3. Can NdFeB magnets be safely machined after magnetization?
Answer:No. Machining magnetized NdFeB magnets is unsafe and can cause cracking, tool damage, or injury. All cutting and grinding operations must be completed before magnetization.
