If so, sufficient filling cannot be performed. Further, it is usually used for a trial purpose, and it is good to make several pieces, but in order to mold many pieces, a silicone rubber mold is used, so the mold life is short and mass production is not possible.

る微小部品の成形方法。1. A base plate, a guide pin on the base plate, and a plurality of cavity plates forming a three-dimensional shape of a minute component with the guide pin as a reference.
It is composed of a fixed plate for fixing the cavity plate so as to be sandwiched between the base plate, the base plate, the cavity plate, and the fixed plate. A mold for forming a fluorine-based monomolecular film is placed in a vacuum atmosphere, and separately from the vacuum atmosphere, it is placed in a tank that can be in a vacuum state and cured with the main component of the defoamed two-component resin. A method for molding a microparticulate, characterized in that a fixed amount of the agent is discharged, injected into the cavity, then returned to atmospheric pressure, injected again into the cavity under atmospheric pressure, and then cured.
