Abstract

An injection-molding process including kneading functional particles with a binder resin in a kneader, temporarily storing the kneaded material supplied from the kneader in a reservoir device and feeding the kneaded material stored in the reservoir device to an injection device, the reservoir device including a pair of reservoirs, the kneaded material stored in one reservoir device is fed to the injection device where the kneaded material is then injection-molded, and simultaneously the kneaded material is fed from the kneader to another reservoir device and stored in it. Then, the kneaded material stored in the other reservoir device is fed to the injection device where the kneaded material is then injection-molded, and simultaneously the kneaded material is fed from the kneader to the one reservoir device and stored in it, so that the injection molding process is conducted by alternately repeating the above steps by switching operations. This injection-molding process is capable of producing a molded product of uniform quality by preventing feed pressure of the kneaded material fed to an injection device from being transmitted to the kneader.
