Powder Metallurgy vs Metal Injection Mold
| POWDER METALLUGRY | METAL INJECTION MOLDING (MIM) | |
| 50-100pm | Powdered Particle Size | 2-15pm |
| 92% (Max) | Relative Density | >95-99% |
| 2-20mm | Wall Thickness | 0.30 -10mm |
| Medium | Component Complexity | High |
| 1-1,000g | Weight | 0.01-200g |
| 0.1-2.0% | Tolerance | 0.3-0.5% |
Choosing Between Powder Metal and MIM:
- MIM is excellent for complex shapes
- MIM requires high temperatures to sinter
- MIM parts go through approximately 25% shrinkage
- MIM is expensive
Powder Metallurgy Basics:
- Begin with blending or mixing specific types of metal powders and lubricants.
- Place the mix in a die to create a certain shape.
- Use a press to compact the metal powder tightly.
- Sinter the compressed part in a furnace to form metallurgical bonds in the metal powder.
