PolyAlloys Injected Metals, a division of PSM Industries, Inc., offers our customers a new dimension in shape complexity and component performance by utilizing Metal Injection Molding (MIM). MIM can economically produce complex shapes beyond the capability of conventional Powdered Metallurgy.

Metal Injection Molding is capable of making parts with features such as OD/ID threads and undercuts without the need for secondary machining. In addition, the fine particle size used in Metal Injection Molding feedstock allows for sintered densities that are close to theoretical density vs. the 80 ~ 90% density 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.

Benefits of Metal Injection Molding

• 96-98% of Theoretical Density
• Excellent Mechanical Properties
• Avoids Costly Secondary Operations
• Excellent Surface Finishes
• Capable of Extreme 3-D Geometries
• Holds Tight Tolerances
• Extremely Thin Wall Section Capabilities
