    MIM’ Manufacturing Capabilities


    CMI offers customized metal injection molding services with the following production capabilities:
    Parts Mass: CMI is capable of producing MIM parts weighing from 0.2 to 100g.
    Size: Part diameters of 1 to 30mm are available.
    Wall Thickness: In most cases, we can manufacture parts with a minimum wall thickness of 0.5mm, while some products can reach a wall thickness of 0.25mm. Avoid components over 12.5 mm thick.
    Tolerance: For most metal injection molded parts, we can control the tolerance within ±0.5%, and for particularly small products, we can achieve ±0.2%.
    Density: The density of most MIM parts can be achieved 98%.
    Surface Finish: Typically, the surface roughness of our manufactured MIM parts can reach 1 μm Ra, and 0.3 to 0.5 μm Ra is also possible.
