| 简介 |
A production method for a case-integrated bonded magnet includes : filling a tubular cavity with a magnet raw material that includes a rare-earth magnet powder and a thermosetting resin binder; heating the magnet raw material to cause the thermosetting resin softened or melted while compressively molding the magnet raw material to obtain a tubular compact; discharging the tubular compact from the tubular cavity while press-fitting the tubular compact into a metal tubular case having an inner peripheral surface coaxial with the tubular cavity; and heat-curing the tubular compact with the tubular case to cure the thermosetting resin. The tubular compact press-fitted into the tubular case is thermally cured thereby causing the tubular compact to transform to a tubular bonded magnet, which expands unexpectedly due to heat. |
