PolyAlloys, PSM's metal injection molding (MIM) division, offers our customers a new dimension in shape complexity and component performance. Metal injection molding can economically produce  complex shapes beyond the capability of conventional P/M. It is capable of making parts with features such as OD/ID threads and undercuts without the need for secondary machining. The fine particle size used in MIM feedstock allows for sintered density of close to  theoretical density vs. the 80 ~ 90% achievable through conventional press/sinter. The combination of fine grain size and high density gives MIM components properties matching those of their wrought counter parts.
