According to Fictiv's comprehensive manufacturing cost analysis, the breakeven point between CNC machining and die casting typically falls between 1,000-5,000 units, depending on part complexity and material selection ^[1].

Matson Metal's decision framework provides a more granular analysis with real-world case studies ^[2]:

Real Case Study: A Canadian mining equipment buyer saved $240,000 CAD by choosing CNC-from-casting-blank over pure die casting, eliminating $40,000 in tooling costs while maintaining 18-month repeat order relationships ^[2].

Breakeven Volume Analysis by Alloy Type

Alloy Type	Breakeven Volume (units)	CNC Cost/Unit	Die Casting Cost/Unit	Recommendation
Aluminum (simple geometry)	60-150	$15-25	$8-12 (after tooling)	CNC under 150 units
Aluminum (complex geometry)	200-400	$25-45	$12-20 (after tooling)	CNC under 400 units
Zinc Alloy	300-600	$20-35	$10-18 (after tooling)	CNC under 600 units
Steel/Stainless	400-800	$30-55	$15-25 (after tooling)	CNC under 800 units

Note: Breakeven volumes vary based on part size, complexity, and secondary operations required ^[2]

Key Cost Drivers to Consider:

1. Tooling Investment: Die casting requires significant upfront mold investment ($5,000-$25,000+), while CNC machining has minimal setup costs. For Southeast Asian SMEs testing new products on Alibaba.com, CNC allows market validation without major capital commitment.

2. Unit Cost Trajectory: CNC unit costs remain relatively constant regardless of volume, while die casting unit costs drop significantly at scale due to tooling cost amortization.

3. Secondary Operations: Both processes may require finishing (polishing, plating, anodizing), adding 3-5 days per vendor and additional costs. CNC parts typically require less post-processing due to superior as-machined surface finish.

4. Hybrid Approach: Matson Metal recommends a cast+machine hybrid strategy for many applications, where rough shapes are cast then precision features are CNC-machined, saving 30-50% compared to pure CNC while maintaining critical tolerances ^[2].
