Manufacturing Process
Special-Shaped Forming:
-Compression Molding: Powder cold-pressed at 800-1,500 MPa → Regular complex shapes
- Extrusion Molding : Powder heated to 50-100°C → Injected into molds → 90-95% theoretical density (Ideal for elongated/tubular shapes)
Sintering & Post-Processing:
- Vacuum Sintering:
1050-1180°C at ≤10⁻³ Pa → >98% theoretical density
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
