Quality Assurance: A Full-Process Testing System Ensuring Safety

Raw Material Control: Each batch of rare earth raw materials is tested by a spectrometer to ensure that the content of elements such as neodymium and boron meets the standards, rejecting recycled material doping.
Process Monitoring: Real-time monitoring of magnetic field distribution, dimensional accuracy, and coating adhesion during production. AI visual inspection equipment is set up for key processes, with the defect rate controlled below 0.3%.
Finished Product Testing:
- Magnetic performance testing: Use gauss meters and hysteresis loop testers to ensure that parameters such as magnetic induction intensity and coercive force meet the standards;
- Environmental testing: Verify weather resistance through high and low-temperature alternating test chambers and damp heat test chambers, simulating extreme use scenarios;
- Reliability testing: Drop test (1.5m free fall), vibration test (frequency 20-2000Hz) to ensure no magnetic damage during transportation and use.

FAQ

Q1: Can your ring-shaped neodymium magnets fit Magsafe wireless chargers from different brands?
A: Our ring magnets are designed with standardized precision (tolerance controlled at ±0.05mm), compatible with magnetic modules of mainstream Magsafe chargers on the market. For customization, simply provide your specific dimensions and magnetization direction requirements—our technical team will optimize the design to ensure perfect fit.

Q2: What is the temperature resistance of the product? Can it withstand high temperatures in vehicle-mounted environments?
A: Standard models resist up to 100℃, while special processes enable heat resistance up to 230℃. For vehicle applications, we’ve customized radially magnetized ring magnets with 150℃ resistance for North American clients, which passed strict high-low temperature cycling tests to ensure stable performance.

Q3: What is the minimum order quantity (MOQ)? How long does sampling and mass production take?
A: We support low MOQ sampling starting from 1 pieces, with a 2-day sample lead time. Mass production typically takes 3-5 days, ensuring quick response to your needs.

Q4: How do you ensure long-term stability of magnetic performance?
A: We implement full-process quality control: raw materials are tested for purity via spectrometers; magnetic field distribution is monitored in real-time during production; finished products undergo magnetic performance tests (using gauss meters and hysteresis loop testers) and reliability tests (drop, vibration, etc.). All products comply with ISO9001 and come with complete inspection reports.

Q5: Besides NiCuNi plating, what other surface treatment options are available?
A: In addition to standard NiCuNi triple-layer plating (salt spray test ≥72 hours), we offer epoxy encapsulation, rubber coating, gold plating, zinc plating, and more—tailored to waterproof, scratch-resistant, or anti-corrosion requirements for different scenarios.
