Description

Technical Field

[0001] This application relates to the field of neodymium iron boron (NdFeB) magnet production technology, and more particularly to an automated equipment for NdFeB magnet production. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets can be divided into two types: bonded NdFeB and sintered NdFeB. Bonding is essentially injection molding, while sintering is formed by vacuum heating at high temperatures. NdFeB magnets are currently the strongest permanent magnets at room temperature (their magnetism is second only to holmium magnets at absolute zero, but at room temperature, their magnetism is far stronger than all known permanent magnets). Material grades range from N35 to N52; various shapes can be processed according to specific requirements: round, square, perforated, magnetic tiles, magnetic rods, convex, trapezoidal, etc. Despite these advantages, the surface is prone to rust, so protective surface treatments are usually required: nickel plating, zinc plating, gold plating, epoxy resin plating, etc. The applicable ambient temperature for ordinary NdFeB magnets is below 80 degrees Celsius, and the Curie temperature is 320–380 degrees Celsius. They are mainly used in electronics, electrical appliances, packaging, motors, toys, leather goods, automotive machinery, etc.
