1. MIM vs CNC Cost Comparison: Key Factors
| Cost Factor | MIM Process | CNC Machining | Analysis |
|---|---|---|---|
| Tooling Cost | $20k-$80k (for 10k+ orders) | No tooling, but high programming costs | CNC is cheaper for small batches |
| Material Utilization | >95% (near-zero waste) | 40-60% (material loss) | MIM reduces material costs by 30% |
| Unit Cost (10k pcs) | $1.5-$4.0 (stainless steel) | $5.0-$15.0 (complexity-dependent) | MIM saves 50% for high volumes |
Case Study: A medical device manufacturer reduced total costs by 45% by switching surgical forceps from CNC to MIM (50k units/year).

2. Performance Comparison: Beyond Cost
- Density: MIM (96-99%) is close to wrought metal; CNC is 100% but negligible in practical terms.
- Surface Finish: CNC (Ra 0.8-1.6μm) is smoother for optics; MIM (Ra 1.6-3.2μm) meets most industrial needs.
- Design Freedom: MIM supports 0.2mm thin walls/internal cavities; CNC is limited by tool access.
3. How to Choose? A 3-Step Guide
- Part Weight: <200g → MIM; >5kg → CNC.
- Volume Needs: >10k pcs → MIM; <1k pcs → CNC.
- Complexity: Internal cavities/thin walls → MIM; simple geometries → CNC.
