PURPOSE:To mold a fine thin-valid part used in various small-sized electric products or precision machines, to extend the life of a mold and to also enable mass production. CONSTITUTION:The three-dimensional shape of a fine part is formed on the basis of a guide pin by a plurality of cavity plates 3, 4, 5 and these plats are held and fixed between a base plate and fixed plate and a fluorine monomolecular film is formed to all of plates. This mold is placed under vacuum and the main agent 15 and curing agent 16 of a two-pack type resin defoamed within other vacuum tanks 13, 14 are injected in the cavity by a metering, mixing and emitting mechanism 17 and the cavity is returned to the atmospheric pressure to perform atmospheric pressure injection and curing. When flow is inferior, pressure injection can be also performed by a pressure mechanism. By this method, a fine thin-walled part can be molded. |
