PURPOSE:To easily handle a molded body, to prevent the molded body from being oxidized and to reduce the contend of oxygen in a magnet by a method wherein the molded body obtained by a molding process is immersed in a hydrophobic organic-substance liquid. CONSTITUTION:A molded body 19 obtained by molding a raw material between an upper metal mold 14 and a lower metal mold 15 is conveyed onto a carrying- out belt 20 via a chute 18, it is housed further inside a hydrophobic organic- substance liquid container 5 via a chute 23, and it is transferred into a conveyance belt 24 which is arranged in a hydrophobic organic-substance liquid 5a. Then, in a process in which the molded body is transferred onto the conveyance belt 24, it is passed through the hydrophobic organic-substance liquid 5a, its surface is wetted with the hydrophobic organic-substance liquid 5a, and it is set to a state that it does not come into direct contact with the air. Thereby, the molded body can be handled easily its oxidation can be prevented, and the content of oxygen in a rare-earth permanent magnet can be reduced. |
