Risefull Development Limited

Risefull Development Limited provides a wide variety of Sintered NdFeB permanent magnets. Sintered NdFeB permanent magnets are widely used in different applications (ie. AC motors, DC motors, generators, magnetic separators, magnetic water treatment device, magnetic fuel saver, magnetic pulse sterilization, lifting magnets and other automotive, electronics, electrical fields).

Bonded NdFeB permanent magnets were first introduced in the 1970s. During this period of time, Sintered NdFeB permanent magnets have dominated the market; however, Sintered NdFeB permanent magnets cannot be produced in precise shapes and size. Also, during the production process, they tend to crack and break and it was not easy to assemble. This result of a limitation on applications. In order to solve this problem, NdFeB permanent magnet powder was developed. By mixing the magnetic powder with plastic and compressing into different shape and size. Bonded NdFeB permanent magnets were then introduced in the market and this is probably the most earliest manufacturing method for producing bonded NdFeB permanent magnet. Due to the advantages of Bonded NdFeB permanent magnets (ie. competitive cost, high dimensional accuracy, flexible in shape, good mechanical strength, light weight), this made bonded NdFeB permanent magnets widely used in all kinds of applications with an annual growth of 35% and it has ​​rapid development even since.
