Manufacturing Technique for Raw Material of Sintered Neodymium Magnet by china-magnets-source-material.com

• Smelting (ingot casting) – to smelt metal like Fe, Nd, B and others into a composition (magnet raw material)
• Fragmentation (hydrogen and mechanical disruption) – to crush ingot casting into particle 0.5-2mm
• Powder process by air-current mill – to grind smaller micron particles
• Compression moulding – to press powder into a certain shape
• Sintering, ageing – to sinter powder solid
• Performance test – to test magnetic property and magnet appearance
