The invention provides an improved powder injection molding injection material, which comprises: a sinterable powder and a binding agent. The binding agent comprises a hydrocarbon wax, a surfactant, a polyene compound, polyoxymethylene, and a rheology modifier. By including the rheology modifier, the powder injection molding injection material of the present invention reduces the powder injection molding injection material into an expanding fluid in a region of high shear strain rate (high shear rate), so that the powder injection molding material can be maintained at a high level. In the case of injection speed, the quality of the product is increased. |
