  • Method of resin-sealing laminated core
    Patent number: 9520218
    Abstract: A method of resin-sealing for a laminated core includes the steps of: holding by sandwiching a core body 11 between a resin injection mold 20 and a supporting mold 21; extruding a molten resin using a plunger 37 from a resin reservoir pot 24 provided in the resin injection mold 20; and resin-sealing the permanent magnets 18 in the magnet insertion holes 16 and 17, wherein a material of the resin reservoir pot 24 of the resin injection mold 20 and a region through which the resin passes from the resin reservoir pot 24 is a superhard material, and wear in the resin injection mold 20 due to a flow of the resin is reduced. With this, a gap between the resin reservoir pot 24 and the resin injection mold 20 due to a difference in thermal expansion is less easily produced.
