Neodymium Magnetic Materials Multipole Magnetized Strong Bonded NdFeB Ring Magnets

Bonded NdFeB magnets, i.e. bonded neodymium iron boron magnets, are those permanent magnetic materials made of rapid quenched NdFeB magnetic powders combined with resin binders (epoxy, Nylon/polyamide (PA), polyphenylene sulfide (PPS), etc). They are manufactured through a bonded process (compression, injection, extrusion or calendaring molding), so it is available to obtain complex geometries with high dimensional precision. Controlling the performance and proportion of NdFeB magnetic powders, it is able to adjust the magnets’ magnetic properties in a continuous range. Due to their complex geometries availability, high dimensional precision, uniform magnetic properties, diverse magnetization patterns, good corrosion resistance and mechanic properties.

Feature

(1) As it has higher magnetic force, injection molding is possible and dimensions are accurate, it is suitable for high precision parts.

(2) As it is isotropic, expensive magnetic field molding machine and tooling are not required, it is possible to produce relatively low cost parts.

Application

Compact Motor

Actuator

Compact Sensor
Bonded neo powder is incorporated into numerous end market applications that utilize bonded neo magnets. These products are primarily motors and sensors used in a range of products, including computer and office equipment (e.g., hard disk drives and optical disk drive motors and fax, copier and printer stepper motors), consumer electronics (e.g., personal video recorders and mp3 music players), automotive and industrial applications (e.g., instrument panel motors, seat motors and air bag sensors) and home ventilation systems (e.g., ceiling fans).

Packing:
As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton.

+By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.
+By Sea: If the goods are will be shipped by sea, we will place a pallet on the bottom of cartons.

Shipping:

Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
A: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
B: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
C: The weight is over 100Kgs, we recommend to send them by Ocean.

Bonded magnet is Customized product.
