metal Injection Molding advantages:
1. Effective cost with complex design and good performance
Allows design freedom to manufacture complicated shapes than other methods.
High productivity to make small precision parts, quick and efficient.
Complex products can be with small holes, thin walls and fine surface detail, internal and external threads, knurling, finely detailed surface textures, engravings and markings.

2. Material Variety
Superior strength, magnetic, and corrosion properties due to high density achieved when compared to conventional powdered metal, plastics and die-casting.
Net shape components from otherwise hard to process materials like carbide, Tungsten alloys and Titanium.
Isotropic and homogeneous microstructure for uniform material properties.
Capability to create alloys that are not available in wrought or cast form.
