Metal Injection Molding (MIM)
MIM is an advanced technology that combines the shape-making capability of Plastic Injection Molding and the metal flexibility of powder metallurgy. It provides a new alternative from conventional forming technologies .MIM minimizes machining and secondary operations through net shape production while produce small intricate metal components.

By taking advantage of extremely accurate mold, injection, and design flexibility, MIM would be able to offer cost efficient for moderate-to-high production volume to manufacture parts that require more complex Geometries

Characteristics :
  1. Complex Shapes
    3-dimensional parts can be produced. Suitable for intricate and complex Geometries.
  2. Good Dimension Control
    within +/- 0.4% general tolerance can be achieved by accurate molding and sintering. Utilizing proper post machining, products tolerance can be promoted to m order.
  3. High Material Density & Strength
    Good mechanical properties resulted from the Relative Density > 96%
  4. Good Surface Finishes
    The surface before processing is good enough for most applications without further process and good for surface treatment (such as polishing, bluing).
  5. Wide Range of Available Alloys, Composites, and Properties
