1.1 The types of magnet we can supply
Neodymium magnet (also known as NdFeB, Nd2Fe14B, NIB or Neo magnet), the most widely used type of rare earth magnet and the world's largest permanent energy product materials.In 1982, Sumitomo Special Metals Sagawa live (Masato Sagawa) found neodymium magnets. It is the most commonly used in electronic products, such as hard drives, mobile phones, headsets, and battery-powered tools. To prevent corrosion damage, the need to make the magnet material surface protection treatment, for example, gold, nickel, zinc, tin plating, and the surface coating such as epoxy resin.

1.7 Great engineers manufacture great magnet product !
1.8 Detailed Four Step High quality magnet board with integrating quality control !
STEP 1: After sintering, the mould comes out. Test the size, tolerance and the property (BH(max), Br, Hcj, Hcb) of the mould, only the qualified products turn to next step.
Magnet performance standard: GB/T 13560-2009
Quality control: MIL STD 105E=ISO 28591=NF X 06 022, LEVELⅡ
STEP 2: After grinding, inspect the size and tolerance of the magnet with precision before coating, only the qualified products turn to next step.
STEP 3: After cutting the thickness, examine the tolerance of thickness, guass and pull force, only the qualified products turn to next step.
STEP 4: Recheck the coating, size and tolerance, surface of the magnet, exclude the unqualified (damaged, bad coating) pieces, then come to magnetizing and packaging.
