C. We provide magnets for a dozen of Fortune Global 500 enterprises such as Apple, Samsung, Lenovo etc.

D. In Europe market, 80% permanent magnets used for range hood are from AIM Magnet Co.,Ltd.

E.Our company is the main supplier of American top wine box.

F.With rich exporting experiences with neodymium magnets,we build supply chain to offer neodymium magnets with professional service.

2. Can you make custimized magnets?

Yes.In order to offer best price for you,could you advise the size,grade,and coating you need.If have drawing, please provide for our reference.

3. How to ensure the quality?

As a professional neodymium magnet manufacturer,we can control all process,from raw material to cutting to coating and

packing.Our QC will do careful inspection on every step.

4.If neodymium magnet can no coating?

In NdFeB components, iron is more than 60%. If the magnets are exposed to air without plating, it will rust and thereby affect magnetic force. Electroplating cost is low , and helpful to extend magnet working life. Further, if no coating, magnets don’t need to be chamfered, so the sharp edges will also affect the use effect.

5. What kind of packaging do you used in the export transportation?

Our packing is Standard air packing.We put iron sheet and foam into carton,to separate magnetic force.This packing is very safe when shipping.

6. How to shipping neodymium magnet?

DHL, Fedex, UPS, door to door service/ air shipping/ sea shipping.
