Abstract
Provided is a method for manufacturing a high-density integrally-molded inductor, comprising the following steps: (1) winding an enameled wire coil to be spiral; (2) mechanically pressing first ferromagnetic powder into a magnetic core; (3) mounting the magnetic core into a hollow cavity of the enameled wire coil; (4) mounting the enameled wire coil provided with the magnetic core into an injection mold; (5) uniformly mixing and stirring resin glue, a coupling agent and an accelerant, to obtain high-temperature resin glue; (6) uniformly stirring second ferromagnetic powder and the high-temperature resin glue, to obtain a magnetic composite material; (7) injecting the magnetic composite material into a mold cavity of the injection mold for molding, and solidifying the magnetic composite material to obtain an outer magnet; and (8) cooling and de-molding the outer magnet, to obtain a molded inductor.
