[0026] Example: uniformly mix anisotropic NdFeB magnetic powder with 0.5wt% binder and 0.15wt% curing agent, then put it into a split mold 8 with an inner diameter of φ4mm and a height of 5mm, and vibrate while loading Real, and at the same time apply a 1.2T magnetic field treatment, heating to a temperature of 110°C with a resistor 7. The parameters of the laser pulse beam 3 are that the spot diameter is φ4mm, the wavelength is 532nm, the pulse width is 8ns, and the energy of the laser pulse is 200mJ. After the above-mentioned laser-induced shock wave punching, after cooling in the split mold 8 for 45min, a φ4mm ×4mm anisotropic bonded NdFeB magnet, the magnet properties are: remanence Br=0.725T (Tesla), intrinsic coercive force jHc=689KA / m, maximum energy product (BH) max=85KJ / m 3 .
