The Steel Mold Trap: Why Traditional Methods Fail Small Batches
When producing 5-500 units, steel tooling creates unsustainable burdens:
- 15k−80k in mold development costs
- 8-14 week delays before first article inspection
- ±0.2mm tolerance limitations for complex geometries
Our Small Batch Production without Steel Molding methodology eliminates these barriers through: - Silicone & composite tooling (3-7 day turnaround)
- Vacuum/pressure casting (±0.05mm accuracy)
- Digital workflow integration (AI-driven DFM analysis)
