Method of manufacturing rust-preventing cover |
摘要 |
A method of manufacturing a rust-preventing cover in which sufficient strength during mounting is ensured and which can be easily removed when not needed. The method of manufacturing a rust-preventing cover is carried out by a WFM manufacturing method rather than a conventional DFM manufacturing method. A mixed aqueous solution having paper fibers as a main material thereof is stored in a water tank. A porous rust-preventing cover mold is immersed therein. Then, the mixed aqueous solution is sucked by a vacuum pump. In this way, a paper fiber surface layer, which later becomes a rust-preventing cover, is formed on a surface of a mold main body of the rust-preventing cover mold at portions to which masking has not been applied. By adjusting a suction time of the vacuum pump, a rust-preventing cover of an arbitrary thickness which corresponds to a thickness required during mounting can be obtained. Further, because breakage strength of the rust-preventing cover is based on bonding of paper fibers, the rust-preventing cover can be broken and removed easily.
