Is die casting expensive?
Is Die Casting Expensive? A Cost Analysis
Die casting costs depend on factors like production volume, part complexity, material choice, and tooling requirements. While it can be expensive upfront for low-volume projects, it becomes highly cost-effective for mass production. Below is a detailed breakdown of costs and scenarios where die casting shines or falters.
1. Key Cost Drivers
| Factor | Impact on Cost |
|---|---|
| Tooling (Mold/Dies) | High initial cost (10,000–10,000–100,000+) for hardened steel dies. Dominates low-volume projects. |
| Material | Aluminum (2–4/kg),zinc(2–4/kg),zinc(3–5/kg), and magnesium ($5–8/kg) affect per-part costs. |
| Production Volume | High-volume runs (10,000+ units) reduce per-unit costs significantly. |
| Part Complexity | Intricate designs (undercuts, thin walls, cores) increase tooling and cycle time costs. |
| Secondary Processes | Machining, anodizing, or powder coating add 0.50–0.50–10+ per part. |
2. Cost Comparison with Other Processes
| Process | Tooling Cost | Per-Unit Cost | Best For |
|---|---|---|---|
| Die Casting | 10,000–10,000–100,000+ | 1–1–50+ (high volume) | Mass production of complex metal parts. |
| Plastic Injection Molding | 5,000–5,000–50,000 | 0.10–0.10–10+ | High-volume plastic components. |
| Sand Casting | 1,000–1,000–20,000 | 10–10–100+ | Low-volume, large, simple parts. |
| CNC Machining | Minimal (no molds) | 50–50–500+ | Prototypes or low-volume metal parts. |
3. When Die Casting Is Cost-Effective
- High-Volume Production (10,000+ units):
- Tooling costs amortize over many parts, driving per-unit costs down (e.g., 1–1–5 for aluminum auto parts).
- Complex Geometries:
- Thin walls, internal channels, and fine details are cheaper to cast than machine.
- Material Efficiency:
- Near-net-shape casting minimizes waste vs. machining from solid billets.
Example:
- Producing 50,000 aluminum car door handles via die casting might cost $3 per unit (including tooling).
- Machining the same part could cost $20+ per unit due to material waste and labor.
4. When Die Casting Is Expensive
- Low-Volume Production (<1,000 units):
- High tooling costs dominate (e.g., a 50,000diefor500parts=50,000diefor500parts=100 per part).
- Simple Parts:
- Basic shapes are cheaper to produce via sand casting or stamping.
- Exotic Materials:
- Magnesium alloys or specialty aluminum grades (e.g., A356-T6) raise material costs.
Example:
- A prototype run of 100 zinc alloy brackets could cost **150+perunit∗∗(vs.150+perunit∗∗(vs.10 via CNC machining).
5. Hidden Costs to Consider
- Design Changes: Modifying a die costs 1,000–1,000–10,000+ depending on complexity.
- Maintenance: Dies require periodic refurbishing (5–10% of initial cost annually).
- Energy: High-pressure machines consume significant electricity, adding 0.05–0.05–0.50 per part.
6. Cost-Saving Tips
- Optimize Design: Simplify geometries, avoid undercuts, and standardize wall thickness.
- Use Multi-Cavity Molds: Produce multiple parts per cycle (e.g., 4–8 cavities).
- Choose Standard Alloys: A380 aluminum or Zamak 3 zinc are cheaper and easier to cast.
