Metal Injection Molding (MIM)
Precision Parts with Design Freedom
Complex Geometry Made Possible
Metal Injection Molding (MIM) enables the production of small, complex, and high-precision components that are difficult to achieve through machining. NEWLIFE offers full MIM solutions based on self-developed feedstock.
Controlled Process Chain
From feedstock formulation to injection molding, debinding, and sintering, every step is tightly controlled to ensure predictable shrinkage and stable quality.
Metal Injection Molding (MIM) primarily replaces precision CNC machining and small precision casting for complex, high-precision metal components produced in medium to high volumes.
Key Manufacturing Processes Replaced by MIM
1. Precision CNC Machining (Primary Replacement)
This is the main market segment where MIM creates the most value.

MIM replaces machined parts that are:
- Small and geometrically complex
- Requiring tight tolerances
- Produced in medium to large quantities
- Cost-sensitive at scale
Typical applications:
Medical devices, electronics components, precision mechanical parts, non-magnetic parts
2. Small Precision Casting (Investment Casting)
MIM also competes with investment casting when finer detail and tighter tolerances are required.

MIM advantages over casting:
- Better dimensional consistency
- Reduced finishing and machining
- Improved surface quality
3. Multi-Part Machined Assemblies
MIM often replaces assemblies made from multiple machined components.
Traditional solution:
Multiple machined parts + assembly
MIM solution:
Single integrated MIM component
Benefits:
- Part consolidation
- Reduced assembly cost
- Improved reliability
Where MIM Is Not the Best Choice
MIM is not designed to replace:
- Large or heavy metal components
- Simple geometries with very low tolerance requirements
- Ultra-high precision CNC machining (below ±5 μm)
- Low-volume or prototype-only production
Market Position of Metal Injection Molding
MIM occupies the space between precision CNC machining and micro-casting, delivering complex geometry, high precision, and cost efficiency at scale.
Application Focus
MIM is ideal for medical devices, electronics, automotive precision parts, and non-magnetic components requiring accuracy and design flexibility.
