Melting

The materials are exposed to mid frequency and melted in an induction furnace.

Jet Milling

After completion of various process steps, the ingots are pulverized intoparticles that are several microns in size. In order to prevent oxidation from occurring, the small particles are protected by nitrogen.

FacilitiyFacilitiy

The magnetic particles are placed in a jig and a magnetic field is applied while the magnets are pressed into shape. Through this process, we achieve magnetic anisotropy.

Pressing

FacilitiyFacilitiy

The magnetic particles are placed ingots that have been pressed are heat treated in a sintering furnace. The density of the ingots prior to sintering is about 50% of true density but after sintering, the true density is 100%. Through this process the ingots' measurement shrink by about 70%-80% and their volume is reduced by about 50%.

Sintering

FacilitiyFacilitiy

Basic magnetic properties are set after the sintering and aging processes are complete. Key measurements including remnant flux density, coercivity, and maximum energy product are recorded.Only those magnets that pass the inspection are sent to subsequent processes including machining and assembly

Inspection

Facilitiy

Due to shrinkage from the sintering process, required measurements are achieved by grinding the magnets withabrasives.Diamond abrasives are used for thisprocess because the magnet is very hard.

Machining

Facilitiy

Magnets that have been machined and plated are measured and visually inspected.To ensure the high precision, we have totest the size in order to control the tolerance.

Inspection

FacilitiyFacilitiy

Magnets that have been machined and plated are measured and visually inspected. In addition, magnetic properties, corrosion and maximum energy are tested to specifications.

Magnetization

Facilitiy

Magnets that have passed product testing are packaged and shipped. Flux leakage shields are utilized for air shipment when required. Xinfeng magnet products are shipped from Ningboto worldwide customer locations
