How do you ensure safe shipping?

We use safe, high-quality export packing. Air shipments use vacuum and iron shield packing to prevent demagnetization. Sea shipments use wooden pallets or cases for safety and environmental protection.

Can I visit your factory?

Yes, you are welcome to visit our factory at any time. We will arrange everything for your arrival.

How can I compare the quality of different NdFeB magnets?

Consider factors like raw material purity, manufacturing process, and post-processing. High-quality magnets have low impurities, few defects, and are well-manufactured for good performance.

How should I store NdFeB magnets?

Store in a dry, cool place away from heat sources and other magnets. Handle carefully to avoid damage as they are brittle. Keep away from electronic devices to prevent interference.

Can you provide the best price quote?

Prices vary based on many factors. Price is not always an indicator of quality. We strive to quote the best price to meet your targets, believing the most suitable option is the best.
