Manufacturing Process

The product is manufactured through the following key processes:

● A high-speed grinding wheel shapes the magnet's surfaces with tight dimensional tolerances.

● Coolant fluid is applied to control heat, reduce surface stress, and ensure a smooth finish.

● The result is a uniform, precisely dimensioned magnet with clean edges—ideal for high-performance applications.

This precision step is essential for ensuring that the final magnets meet strict quality standards for use in motors, sensors, electronics, and aerospace components

Apperance & Dimensional Inspection

Visual Inspection: Under standardized lighting, trained QC staff check for cracks, chipping, inclusions, pores, or oxidation.                              

Image Measurement System: High-res 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.

Magnetic Flux Consistency Test: Fluxmeters or Hall-effect testers measure magnetic flux across batches to ensure uniform performance in end-user applications.

  Reliability Test

Impact & Vibration Test: Simulates shipping and usage conditions to ensure operational stability.

Constant Temperature & Humidity Test: Performed under 85°C and 85% RH for 96–500 hours. Performance and appearance are compared before and after testing.

 Packaging & Transportation

Defect Elimination: 100% inspection using calipers, projectors, visual checks, and automated systems to reject cracked, chipped, oxidized, or coated-defective magnets.

Uniform Magnetization & Structured Arrangement: Magnets are uniformly magnetized and arranged for optimal packaging based on customer requirements to ensure performance and facilitate automated assembly.

Vacuum Sealed Packaging: Multi-layer vacuum sealing with moisture barriers, desiccants or nitrogen, prevents corrosion and magnetic interference during storage and shipping.

Customized Outer Packaging: Shock-proof, moisture-resistant, and anti-magnetic leakage packaging (e.g., multilayer cartons, plastic boxes, metal shielding) ensures compliance with international logistics standards. Each box includes a product list, labels, and tracking codes.

 FAQ

Q: How to choose the correct magnetization direction?

Axial Magnetization: Magnetic lines flow through thickness — best for concentrated fields

Radial Magnetization: Magnetic lines radiate outward — for uniform field distribution

Multipole Magnetization: Multiple poles along circumference — for complex fields (e.g., motors, sensors)

Q: What is the maximum working temperature of magnet?

Standard N-series: up to 80°C

High-temp grades (SH/UH/EH): up to 150°C–230°C

Dysprosium-enriched formulations can further enhance temperature resistance
