To enhance these industrial use high adhesive force strong performance high torque electric motor permanent nickel plating sintered neodymium magnets’corrosion resistance, surface quality, and magnetic stability, the following treatments are used:
Edge Reinforcement: Laser cladding with nickel-based alloy at magnet seams (prevents electrochemical corrosion)
Edge Rounding: Reduces magnetic field distortion
Default Coating: Triple layer Ni-Cu-Ni (customizable)
Standard Thickness: Ni (3μm) + Cu (5μm) + Ni (4μm)
Optional Coatings: Gold or silver plating for better conductivity and corrosion resistance
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.
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.
6. 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.
