..to your best source for incredibly strong neodymium rare earth magnets. If you are new to our site, we're glad you found us. We hope we can fill all of your neodymium rare earth magnet needs.

Quality Control

Quality, Cost, Delivey

We always think that it aims to improve the supply, I am satisfied by you: Quality: Quality Cost: Price Delivery. We will make your product by to meet as long as you make use of its position as a magnet manufacturer with a factory in Ningbo China, it is possible to customer requests. As soon as possible, yet we have with our goal to be delivered to customers at a reasonable price, the products to suit the needs of our customers shape, and magnetic properties.

QCD declaration

Magnet manufacturing process

Corresponding to the mass-produced, of course, can also be accommodated in the fabrication of one prototype.
Adopted a magnet manufacturing advanced equipment, as well as produce products of stable quality, our goal is to reduce costs always neodymium factory in Ningbo.

Magnet manufacturing process

Product inspection

I perform magnetic properties of the magnet material by BH tracer, of course, dimensional inspection by state-of-the-art equipment, the surface magnetic flux inspection, the inspection of the PCT, such as neodymium magnet factory in Ningbo.

Product inspection

Inspection reports

To help you use with confidence high-quality products, has put up a test report on the products that you intend to deliver to our customers!!!
The main item in the test report, I have put the test data as follows:

Main items in the inspection report
Equipment name An outline of the product material, product shape and product dimensions based on customer specifications is reflected in the equipment name. For details, see the page on the designation of equipment names.
[ Example ]
NF-39SH
- Represents the material.
W20X35X12
- Gives an outline of product shape and dimensions.
Drawing number Indicates the drawing number in the client's specifications.
Lot No. Represents the manufacturing lot number of the product to be delivered. This number is used for lot control with traceability so that the history of a product?s entire manufacturing process can be traced.
Magnetized or not, marked or not Before delivering the product to the customer, we may give magnetism to (magnetize) the magnet. To confirm it and clarify the direction of magnetization, this confirmation item results in the product being marked.
Magnetic characteristics

To indicate the basic material performance of the magnet to be delivered, we indicate values for the various magnetic characteristics measured with a B-H meter. A demagnetization curve (B-H) curve is also attached.

- Br (residual flux density) 
Indicates the intensity of a magnet?s magnetism.

- Hcb (magnetic coercive force) 
The magnetic field intensity at which the sum of a magnet?s reverse magnetism (when placed in a magnetic field) and the magnetic field applied becomes zero.

- Hcj (essential magnetic coercive force) 
The magnetic field intensity at which the magnetization intensity of the magnet itself becomes zero.

- (BH) max (maximum energy product) 
Indicates the maximum BxH product in the demagnetization curve and represents the maximum magnetic energy possessed by the magnet.

Surface treatment This refers to a processing operation for rustproofing to be conducted mainly on the surfaces of an Nd-Fe-B product (neodymium magnet). Its standard means nickel plating.
Packing specifications In addition to our standard packing specifications, a special method of packing may be adopted as agreed upon with the customer. The basic specifications are indicated here.

Product inspection results

Indicates the measurement data mainly for product sampling inspections. Indicates inspection results for dimensions, surface flux density, appearance, neodymium magnet reliability test (PCT acceleration test), and other inspections.

(1) Dimensional inspection 
Indicates inspection items, inspection method (measuring equipment), specified standard values, measurements taken, and pass-fail decisions.

(2) Surface flux inspection 
Indicates the specified standard values as determined by a Gauss meter, measurements taken, and pass-fail decisions.

(3) Appearance inspection 
Indicates pass-fail decisions based on our standard specifications or customer specifications.

(4) Pressure cooker test (PCT) inspection 
Indicates pass-fail decisions according to our standard specifications or customer specifications.
