ISO9001 Injection Molding NdFeB Magnetic Compound OEM
HCNTP-60HL Melt Flow Rate 210 NdFeB Compound
NdFeB Compound Application
Injection molding NdFeB compouds are a kind of bonded NdFeB products, and are suitable for products formed by injection molding machines. Because of the high precision of injection molding and integrated molding with copper, stainless steel, plastic bearings and other types of inlays, It can be used in micro motors, motor rotors and sensors, automotive motors, and can also be used in household appliances and toys
Nano (Royce3010) chelated film without coating treatment can meet the use in marine climate conditions for 20-30 years, and can be widely used in sea-based wind power generation. The surface bonding force is more than 20Mpa, which can be widely used in permanent magnet high-speed motors, special motors, electric vehicle motors, extra high voltage, high voltage DC power supply systems, fast charging systems, aerospace and military industries, etc.

Preparation process
Batching - melting - powder making - pressing - sintering (sintered NdFeB has) --Processing--magnetization to finished product, processing process includes: polishing, slicing, wire cutting, punching, hole sleeve, plating, etc.
Surface treatment of NdFeB
The common ones are zinc plating (including color zinc, blue and white zinc, etc.), nickel plating, nickel-copper-nickel plating, baking paint, and the uncommon ones are epoxy resin coating, electrophoresis, phosphating, gold plating, silver plating, chrome plating, etc.
Material characteristics
NdFeB has the advantages of high cost performance and good mechanical processing characteristics; the disadvantages are low Curie temperature point, poor temperature characteristics, and easy to powder corrosion, it must be improved by adjusting its chemical composition and surface treatment to meet the requirements of practical applications.
