Title:
METHOD FOR MANUFACTURING FERRITE CORE
Document Type and Number:
Japanese Patent JP2006282412
Kind Code:
A
Abstract:
To provide a method for manufacturing a ferrite core which is excellent in electromagnetic characteristics and injection moldability and which can eliminate a deformation problem after baking.
Ferrite powders, a thermoplastic resin and wax are prepared. The thermoplastic resin and wax are mixed at the rate of 5-10 wt.% respectively to the ferrite powders of 100 wt.%. The obtained mixture is kneaded to be a dispersion degree of 50% or less with heat and the obtained kneaded matter is injection-molded and baked.
