The fastest areas and markets for abrasives in the field of abrasives are: automotive, medical devices, and the growing field of electrical equipment. In 2012, the demand for abrasives was 13.93 million tons. However, due to the strict policy restrictions imposed by the government on the use of silicon abrasives and volatile raw materials, the development of the abrasives market will be inhibited. The global abrasives market will benefit as the growing garnet is used in abrasive blast cleaning and water jet cutting technology.
Global abrasives are divided into: consolidation, coating, raw materials, steel shots and free abrasives, and other abrasive products. In 2012, bonded abrasives accounted for the largest market share, followed by coated abrasives and free abrasive abrasives. In 2012, the sales revenue of bonded abrasives was 12.27 billion US dollars, and in 2019 it will reach 16.71 billion US dollars. According to the end user, the abrasives market is divided into machinery, transportation, electricity and electronic equipment and others. The machinery industry led the abrasives leader in 2012, accounting for 23.8% of the global abrasives, and is expected to increase from $8,586.7 million in 2012 to $12,418.5 million in 2019. According to the countries and regions of the abrasives consumer market, North America, Asia Pacific, Europe and other parts of the world. In 2012, the Asia-Pacific region occupied the main position of global abrasives, accounting for 55.8% of global consumption, followed by Europe.
There are two main Bonded NdFeB Magnet manufacturing methods:
ï‚·Bonded Injection Plastic Moulding NdFeB
ï‚·Bonded Compression Moulding Ndfeb
Bonded Compression Moulding NeFeB Magnets ( called Compression Bonded Magnets) are made by using many isotropic Neodymium, Iron, Boron materials, as well as crushed and powdered Samarium and Cobalt ingredients.Combinations of different elemetal grades are used to creat specific magnetic properties. Compression Bonded Magnets offer higher magnetic strength than Injection Plastic moulded magnets. Although Compression Bonded Magnets have higher magnetic particle density, ther are limeted to simple geometric shapes due to the compaction process. The epoxy is used to protect the magnet surface from industrial solvent and automotive fluids. The normal applications of the magnets range from -40℃ to 150℃.
The advantages of Compression Bonded Magnets:
1. High quantity and even volume manufaturing, with up to millions of pieces per year
2. Single-time moulding and multi-poles orientation.
3. Effective surface treatment to prevent corrosion. The product is coated with epoxy resin to be protect the surface smoothing.
4. Excellent magnetic properties. The energy of Compression Bonded Magnets is 3 times as high as anisotropic ferrite magnets.
Application of Compression Bonded magnets:
•Mini motors
•Automatic contolling devices
•Sensors
•Drivers
•Telecom
