1.Core Advantages of Metal Injection Molding

(Revolutionary Manufacturing Efficiency)

Material Utilization＞98%

• Rejected green parts can be recycled without quality compromise
• 40%-60%cost reduction vs.machining when equivalent density < 2g/cm³

Complex structure Integration

• Enables 0.5mm ultra-thin walls, φ0.2mm micro-holes, and multi-cavity integration
• Eliminates multi-component assembly (reduces tolerance risks)

Mass-Production Cost Advantage

• Minimum order quantity: 10,000 pcs/year (ideal >100,000 pcs)
• Unit cost = 1/3-1/2 of small-batch CNC machining

Engineer’s Note: Green parts require shrinkage allowance (e.g., 10cm → 8.5cm after sintering).

3. MIM-Optimized Structural Features

Equivalent Density Formula: Part Weight (g) / Envelope Volume (cm³)

Example: 27g part with 15cm³ volume → Equivalent density = 1.8g/cm³(77% material waste in machining)

Simplified Guideline: Consider MIM when >70% material is wasted in machining
