Appearance & Dimensional Inspection
Advanced vision measurement systems utilize high-resolution cameras combined with intelligent image-processing algorithms to perform precise non-contact 2D inspections. This method is particularly effective for complex or irregular geometries, delivering fast, consistent, and objective results in high-volume production.
Automated Smart Inspection
AI-powered inspection systems integrate high-speed imaging with advanced algorithms to automatically identify surface defects such as cracks, scratches, and discoloration, as well as dimensional deviations. This fully automated process enhances inspection accuracy, increases yield, and significantly reduces reliance on manual checks.
Reliability Testing
Impact & Vibration Testing
Products are subjected to controlled impact and vibration simulations that replicate transportation and real-world operating conditions, verifying structural integrity and functional stability.
Constant Temperature & Humidity Testing
Magnets are tested in high-temperature, high-humidity environments at 85°C / 85% RH for 96 to 500 hours. Magnetic performance and surface condition are evaluated and compared before and after testing to confirm long-term reliability.
Frequently Asked Questions:
How do different NdFeB grades (N, H, SH, UH, EH) affect high-temperature performance?
Answer:
The main difference lies in intrinsic coercivity (Hcj). Higher temperature grades (H → EH) contain more heavy rare earth elements or advanced grain boundary diffusion, allowing them to resist demagnetization at elevated temperatures, but usually at the cost of slightly lower remanence (Br).
What is the practical difference between Hcj and Hcb?
Answer:
Hcj indicates resistance to irreversible demagnetization and is critical for motors and high-temperature applications. Hcb relates to reversible magnetization loss and is more relevant for magnetic circuit design. Hcj is generally the more important parameter for reliability.
