Quality Inspection Process for NdFeB Magnets
- Incoming Material Inspection (IQC)
All raw materials are sourced from qualified suppliers and undergo chemical composition and particle size verification before production.
- In-Process Quality Control (IPQC)
Key production steps including pressing, sintering, machining, and coating are monitored with defined control parameters to ensure dimensional accuracy and magnetic consistency.
- Magnetic Property Testing
Magnetic performance such as Br, Hcj, Hcb, and (BH)max is tested using calibrated hysteresis graph equipment, in accordance with international standards.
- Dimensional & Tolerance Inspection
Dimensions are measured with precision instruments (CMM, micrometers, gauges) to meet drawing and tolerance requirements

FAQ
Q1. Why are multi-pole magnets more sensitive to manufacturing variation?
Answer:Each pole requires precise magnetization strength and spacing. Small deviations compound across poles, affecting field uniformity and system-level accuracy.
Q2. How does Nd-rich phase distribution affect corrosion resistance?
Answer:Non-uniform Nd-rich grain boundary phases create preferential corrosion paths. Controlled alloy chemistry and coating selection are required to mitigate this risk.
Q3. How can partial demagnetization be detected non-destructively?
Answer:Advanced flux mapping, Helmholtz coil measurements, or system-level functional testing are required. Standard pull-force or spot flux checks are insufficient.
