- Purpose and Quantity
- Prototype Mold: Used for small-batch prototyping (typically 10–1,000 pieces) to validate product design, functionality, and appearance.
- Production Mold: Designed for high-volume mass production (tens of thousands to millions of pieces), focusing on high efficiency, consistency, and low per-part cost.
- Material and Lifespan
- Prototype Mold: Commonly made from aluminum alloy, pre-hardened steel (e.g., P20), epoxy resin, or 3D-printed materials; short lifespan (hundreds to tens of thousands of shots).
- Production Mold: Made from high-hardness tool steels (e.g., H13, NAK80, 8407, S136); long lifespan (500,000–2,000,000+ shots).
- Structure and Precision
- Prototype Mold: Simplified structure (single cavity or few cavities, no hot runner, minimal slides), looser tolerances, short lead time (days to 2 weeks).
- Production Mold: Complex structure (multi-cavity, hot runner system, fully automatic ejection), high precision (±0.01 mm level), longer lead time (4–12 weeks).
- Cost
- Prototype Mold: Low cost, ideal for rapid iteration and design validation.
- Production Mold: High initial cost, but extremely low cost per part when amortized over large volumes.
Prototype molds prioritize speed, low cost, and quick validation; production molds emphasize durability, efficiency, and part-to-part consistency for scaled manufacturing.
