Title: Manufacture of ferrite core
Inventor: INOUE AKIRA
IPC: H01F41/02
Filed: 1993-03-05
Abstract: PURPOSE:To prevent the opening of outer leg by coating an adhesive on both butting surfaces of a pair of ferrite cores, baking them with a pair of ferrite cores butted against each other, and separating them after baking. CONSTITUTION:After a mold is filled with a ferrite material powder, an E- shaped ferrite core is moulded and the butting surfaces of respective leg parts 1 are coated with an adhesive. Then a pair of E-shaped ferrite cores are butted each other for bonding and placed on a baking case 3 for baking. After baking, any force such as impact, etc., are given on the baked core to separate into two E-shaped ferrite cores at ease, and their butting surfaces are applied with finish working such as grinding, etc., as necessary in order to obtain an E-shaped ferrite core. Thus, the butting dimensional accuracy can be improved and the product quality can be also improved, and furthermore manufacturing efficiency can be improved.
