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 environmental protection and safety.

Can I visit your factory?

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

How should NdFeB magnets be stored?

Store in a dry, cool place away from heat sources and other magnets. Handle carefully to avoid cracking due to brittleness. Keep away from electronic devices to prevent magnetic interference.

Can you provide the best price?

Prices vary based on multiple factors. We strive to quote the best price to meet your targets, ensuring the most suitable option for your needs.
