Metal Injection Molding (MIM) Technology
MIM combines plastic molding, polymer chemistry, powder metallurgy and metal materials science. Feedstock is injection molded and sintered to rapidly produce high-density, high-precision, complex 3D structural parts in volume — a new revolution in manufacturing technology.

- Near-net-shape precision — maximum dimensional accuracy without machining; overcomes low density and inhomogeneity of conventional PM.
- High alloy flexibility — works with materials too hard or brittle to machine; uniform density above 95% with wrought-like dynamic properties.
- High efficiency — multi-cavity tooling and ≥98% material utilization make MIM ideal for volume production of small, complex parts.
Key Equipment
- Advanced Hengpu vacuum sintering furnaces
- Professional small-flight-diameter metal feedstock injection machines
- 3D metrology and professional testing laboratory
