摘要： This injection molding method uses an injection molding machine for two-material molding, which comprises a first mold part that is provided with a cavity and a second mold part that is provided with a cavity and is arranged in tandem with the first mold part. This injection molding method comprises: a first molding step wherein a material is injected into the cavity of the first mold part and the material in the cavity is compressed; and a second molding step wherein a material is injected into the cavity of the second mold part. A pressure, which is generated in the second mold part by injecting the material into the cavity in the second molding step, acts on the first mold part, and a compressive force is applied to the material in the cavity in the first molding step.

摘要： In an injection molding method of fiber reinforced resin of the present invention, a resin accumulation region is provided closer to a downstream side than an injection completion position inside a heating cylinder, an injection pressure is given to molten resin that occupies the resin accumulation region in an injection process of a preceding cycle, and a shear force is given to the molten resin that occupies the resin accumulation region in a plasticizing process of a subsequent cycle. An inside of massive reinforcing fibers F is impregnated with the molten resin by giving a high injection pressure to the molten resin that occupies the resin accumulation region. Next, dispersion of the reinforcing fibers is promoted by giving a shear force in the plasticizing process of the subsequent cycle.
