Title:
ANISOTROPIC SHEET MAGNET, AND METHOD AND APPARATUS FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2003318051
Kind Code:
A
Abstract:

To provide a thermoplastic elastomer or thermoplastic composition in which high orientation of anisotropic magnetic powder is possible for high magnetic characteristics, a flexible anisotropic sheet magnet of high orientation and high magnetic characteristics comprising the composition which is productive, and a method and apparatus for manufacturing the same.

The manufacturing apparatus for an anisotropic sheet magnet has a plurality of transportation vessels for transporting a sheet mold provided to a manufacture line comprising process parts including a preheating process, a heat holding process, a magnetic field orientation process, and a cooling process. The transportation vessel has such shape as to pinch the sheet mold with plate-like surfaces. It is plate-like and comprises a bottom part and an upper lid of magnetic material, and is magnetically discontinuous with each other when loaded with the sheet mold.
