Surface Coatings & Environmental Protection
Uncoated NdFeB material is subject to oxidation in humid or outdoor environments. Protective coatings are specified based on operating conditions and mechanical requirements:
Ni-Cu-Ni Coating: Standard metallic multi-layer coating for general industrial environments, enclosed motor housings, and indoor equipment assemblies.
Black Epoxy Coating: Typical consideration for applications requiring an organic protective coating and specified corrosion resistance in humid production settings.
Zinc Plating (Zn): Basic metallic barrier for general structural components and economical assembly fixtures.
Parylene C: Thin conformal coating option for applications with specific surface-protection and dielectric requirements.
Dimensional Tolerances and Machining
Sintered NdFeB materials are shaped using precision grinding, slicing, or Wire-EDM equipment to achieve required final dimensions and structural features:
Holes & Recesses: Execution of through-holes, blind holes, countersinks, and counterbores for mechanical fastener attachment.
Surface Profiles: Machining of alignment steps, retention slots, keyways, edge chamfers, and radiused corners to assist assembly.
Complex Profiles: Production of arc segments for rotating machinery, stepped blocks, and custom-profile components.
Inspection: Critical dimensions are verified using Coordinate Measuring Machines (CMM), optical measurement systems, and air gauges where specified.
Industrial Applications
Motors & Drives: Servo motors, BLDC motors, industrial generators, and actuators.
Automation & Robotics: Positioning systems, robotic end-effectors, holding assemblies, and magnetic fixtures.
Sensors & Encoders: Hall effect targets, proximity sensors, encoders, and magnetic switches.
Magnetic Separation: Drum separators, cross-belt separators, grate magnets, and inline magnetic arrays.
Pumps & Magnetic Couplings: Magnetic drive couplings, fluid-handling pumps, and sealed valve assemblies.
Quality Assurance & Verification
Zhaobao maintains certified management systems covering quality, environmental management, and occupational health and safety, including IATF 16949, ISO 14001, and ISO 45001.
For industrial NdFeB magnets, inspection scope can include dimensional, magnetic, coating, and environmental verification according to the approved product specification.
Dimensional Verification: CMM, optical measurement systems, and calibrated mechanical instruments can be used for critical dimensions and tolerances.
Magnetic Testing: Closed-loop hysteresigraph testing can verify Br, Hcb, Hcj, and BHmax, with surface flux density or pull-force measurement where specified.
Coating Testing: Coating thickness can be checked using XRF, with adhesion testing where required by the product specification.
Environmental Testing: Salt spray and thermal-humidity testing can be arranged for applications requiring environmental validation.
Documentation: Available documentation may include dimensional inspection reports, magnetic test data, Certificates of Conformance (CoC), material certificates, and applicable RoHS/REACH compliance documentation.
