www. xf-magnet. com Xf Mag 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 into particles that are several microns in size. In order to prevent oxidation from occurring, the small particles are protected by nitrogen.
www. xf-magnet. com Xf Mag Pressing 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.
www. xf-magnet. com Xf Mag Sintering 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%.
www. xf-magnet. com Xf Mag Inspection 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

www. xf-magnet. com Xf Mag Machining Due to shrinkage from the sintering process, required measurements are achieved by grinding the magnets with abrasives. Diamond abrasives are used for this process because the magnet is very hard.
www. xf-magnet. com Xf Mag Plating To best suit the environment in which they will be used, the magnets are subject to various surface treatments. Nd-Fe-B magnets are generally susceptible to rust so they are surface treated with nickel or paint.
www. xf-magnet. com Xf Mag Size testing Magnets that have been machined and plated are measured and visually inspected. To ensure the high precision, we have to test the size in order to control the tolerance. So far our normal tolerance reaches +/-0. 03
www. xf-magnet. com Xf Magnetization Magnets that have been machined and plated are measured and visually inspected. In addition, magnetic properties, corrosion and maximum energy are tested to specifications.
www. xf-magnet. com Xf Mag Packing Magnets that have passed product testing are packaged and shipped. Flux leakage shields are utilized for air shipment when required. XFmagnet products are shipped in Ningbo China and to worldwide customer manufacturing locations
