Metal Injection Molding (MIM) — Complex Metal Parts, Simplified
Transform complex metal component designs into high-performance, precision parts. MIM delivers near-net-shape production for miniature, intricate geometries that traditional machining can't match.

Metal Injection Molding (MIM) combines the design flexibility of plastic injection molding with the strength and integrity of metal. It's the preferred manufacturing process for small, complex metal parts that require high precision, excellent mechanical properties, and cost-effective production.
MIM Process Flow
Mixing
Metal powder + binder
Injection
Green part formation
Debinding
Binder removal
Sintering
Final densification
MIM Technical Advantages
High Precision
±0.001mm tolerances achievable
Complex Geometry
Form complex features in one step
Volume Economics
Low cost per part at scale
Near Net Shape
Minimal secondary machining
Four Key Bottlenecks & Our Solutions
Shrinkage Deformation (12%-20% shrinkage)
Shrinkage database + simulation pre-compensation + dedicated fixtures + sizing process
Debinding Defects (bubbles, micro-cracks)
Multi-stage temperature-controlled debinding + atmosphere closed-loop control
Residual Porosity (2%-5%)
Tiered delivery: optimized sintering / HIP hot isostatic pressing for full density
Microstructure Limits (ultra-thin walls, deep narrow channels)
Full chain closed-loop: mold + feedstock + injection + sintering integration
