3. Manufacturing Process

Key production stages:  

- Pulse Magnetization:  

  Field strength/pulse width/cycles optimized per application.  

- Degreasing & Cleaning:  

  Ultrasonic/alkaline cleaning → Enhanced surface purity.  

4. Surface Treatment & Plating  

- Electroless Nickel Plating:  

  Autocatalytic Ni-P alloy → Uniformity/low porosity/corrosion resistance.  

- Electrophoretic Coating:  

  Electrically deposited polymer → Corrosion protection + aesthetic finish.  

5. Appearance & Dimensional Inspection

- Manual inspection (micrometer/caliper)  

- Visual inspection (800-1,200 lux, 20-750px distance)  

- 2D optical measurement (irregular geometries)  

6. Reliability Testing

·  Impact Resistance Test: Simulates shock conditions during transportation or use using an impact testing machine, to assess whether the magnet develops cracks, fractures, or other structural failures under sudden external force.

·  Vibration Resistance Test: Magnets are fixed on a vibration table and subjected to varying frequencies and amplitudes to evaluate structural stability and performance reliability under dynamic conditions.

·  Drop Test: Magnets are dropped from a specified height onto a hard surface to simulate accidental drops during handling or assembly, helping to assess their impact tolerance and durability.

· Bending/Flexural Test: Bending force or repeated flexing is applied to the magnet to evaluate its mechanical integrity and fatigue resistance under stress, especially for thin or irregular-shaped magnets.

7. Packaging Process  

Magnetic-safe protocol:  

1. Reject defective items  

2. Magnetize & align conforming products  

3. Custom quantitation/labeling per box  

4. Vacuum sealing + magnetic shields/buffer pads  

5. Moisture/collision/interference-proof master carton  

(Custom packaging available)  

8. Application Fields
