Our big advantages

 Neodymium bar, block and cube magnets are incredibly powerful for their size, with an approximate pull strength of up to 300 lbs. Neodymium magnets are the strongest permanent, Rare-Earth magnets commercially available today with magnetic properties that far exceed other permanent magnet materials. Their high magnetic strength, resistance to demagnetization, low cost and versatility make them the ideal choice for applications ranging from industrial and technical use to personal projects.

Applications - Neodymium block, bar and cube magnets are useful for multiple applications. From creative crafting & DIY projects to exhibition displays, furniture making, packaging, home and office organizing, medical, science equipment and much more. They are also used for various design & engineering and manufacturing applications where small sized, maximum strength magnets are required. Visit our applications page to learn more. 

Custom Neodymium Block Magnets - We can also custom manufacturer neodymium block magnets to your exact specifications, just send us a special request and we'll help you determine the most cost effective solution for your project. U-POLEMAG has over 18 years of experience in manufacturing complex magnetic assemblies for more technical applications.

Our Services

 

Products Magnetization 

We can do all the magnetization for neodymium magnet including: Axial magnetization/Diametrical magnetization/Radial magnetization/Inner-diameter

multi-polar magnetization/Outer diameter multi-polar magnetization/Surface magnetization/Complex magnetization/Encoder magnetization/Skewed magnetization.

 

In order to offer better understanding of these methods of magnetization, please see below explaination.

 

Standard Packing and Shipment

The package for neodymium we use:  Sea Pallet / Air Carton / Express Packaging / Plastic Tube / Wooden Case / Vacumm Package and any other packing terms as per your requirement.

 

 

Shipping Details:

A: We have a discount price with Fedex and DHL. So if the weight is under 100Kg, you can those two shipping companies. But you can also choose TNT, UPS 

or any other shipping companies if you like. We'll use iron boxes to shield the magnetics force for air shipping.

 

B: When the weight is over 100Kg,we think sea shipping is more reasonable. We have our own forwarder, you can also entrust your own forwarder.

 

C: Anyway, we'll respect your choices.

 

 

 

Payment

 

We accept T/T, Paypal, Western Union, ESCROW and L/C
