Abstract
A shaped body is molded from fine particles such as powder, whiskers and short fibers, by preparing a slurry consisting of the fine particles and a supercritical fluid containing a small amount of binder dissolved therein, and supplying the slurry into a mold cavity through an inlet port, so that the fine particles suspended in the supercritical fluid are stacked in the cavity to form a layer as the supercritical fluid is exhausted out of the mold cavity through an outlet port.
Claims8
A method of forming a shaped body from fine particles, comprising the steps of providing a mold having a mold cavity to form the shaped body and inlet and outlet passages communicating with said cavity, preparing a slurry consisting of fine particles and a fluid maintained in the supercritical state and containing a binder dissolved therein, introducing said slurry into said cavity through said inlet passage, depositing said particles in said cavity while precipitating said binder on the surfaces of said particles, and discharging said fluid in its normal gas state from said outlet passage.
