Abstract
Official abstract text for this publication.
A manufacturing method for a magnet has step of molding magnetic powder under pressure to obtain a molding. The magnetic powder is pressurized using a mold to which a release agent is applied. The release agent is chemical synthesis oil to which an extreme pressure additive is added.
First claim
Opening claim text (preview).
What is claimed is: 1 . A manufacturing method for a magnet comprising: molding magnetic powder under pressure to obtain a molding, wherein the magnetic powder is pressurized using a mold to which a release agent is applied, and the release agent is chemical synthesis oil to which an extreme pressure additive is added. 2 . The manufacturing method for a magnet according to claim 1 , wherein the chemical synthesis oil is one or more chemical synthesis oils selected from polyolefin-based chemical synthesis oil, adipate-based chemical synthesis oil, and polyester-based chemical synthesis oil. 3 . The manufacturing method for a magnet according to claim 1 , wherein the extreme pressure additive is one or more extreme pressure additives selected from a phosphorous-based extreme pressure additive and a sulfur-based extreme pressure additive. 4 . The manufacturing method for a magnet according to claim 1 , wherein the magnetic powder contains a lubricant. 5 . The manufacturing method for a magnet according to claim 4 , wherein the lubricant is a metal soap-based lubricant. 6 . The manufacturing method for a magnet according to claim 1 , wherein the molding under pressure has a plurality of pressurizing steps. 7 . A magnet manufactured by the manufacturing method for a magnet according to claim 1 .
