Rotor injection molding
Name: Rotor Injection Molding Material: NdFeB magnetic ring + POM PBT(15% GF) rotor injection molding Specification: φ17xφ2x13mm Remanence Br0.65-0.72T Coercive force Hcb≥ 424-480kA/m Intrinsic coercivity Hcj≥ 640-800kA/m Maximum magnetic energy product (BH)max72-80KJ/m3 Curie temperature 350 ℃ Density 5.9g/cm3 Surface treatment: electrophoretic black (epoxy) Magnetization direction: radial 12 pole magnetizing Processing method: powder-molding-curing-electrophoresis-rotor injection molding-magnetizing; Rotor injection molding method: put the processed NdFeB rotor magnetic ring into the injection mold cavity and fix it, then inject POM plastic into the inner diameter of the rotor magnetic ring, cool and demold, and remove the injection gate and thimble. The key point of rotor injection molding technology is to control the precision and injection pressure and speed of the magnetic ring, so as not to overflow glue and crack the magnetic ring. After the injection molding of the rotor is completed, the injection molded workpiece is put into the magnetizing coil, and the multi-pole magnetizing is performed along the outer diameter direction.

Rotor injection molding method: put the processed NdFeB rotor magnetic ring into the injection mold cavity, fix it, and then inject it into the inner diameter of the rotor magnetic ringPOM plastic,After cooling and demoulding, remove the injection gate and thimble batch front. The key point of rotor injection molding technology is to control the precision and injection pressure and speed of the magnetic ring, so as not to overflow glue and crack the magnetic ring. After the injection molding of the rotor is completed, the injection molded workpiece is put into the magnetizing coil, and the multi-pole magnetizing is performed along the outer diameter direction.
