In metal fabrication, spinning, stamping, and deep drawing are three common forming processes, each with unique advantages and applications. Below is a detailed comparison in terms of cost, process characteristics, production efficiency, and product suitability to help customers select the optimal solution.
| Process | Principle | Applicable Materials | Typical Products |
| Spinning | Rotating metal sheet + roller pressure forming | Soft metals (aluminum, copper, stainless steel) | Lamp shades, cookware, hemispheres, cones |
| Stamping | Die-based cutting/bending/shallow drawing | Thin sheet metals (aluminum, steel, etc.) | Electronic enclosures, automotive parts, hardware |
| Deep Drawing | Multi-step deep forming (annealing required) | Ductile metals (aluminum, steel, copper) | Cans, cups, deep-cavity containers |

(1) Cost Analysis
| Cost Factor | Metal Spinning | Stamping | Deep Drawing |
| Tooling Cost | Low (simple mandrel) | High (precision dies) | Medium (multi-stage dies) |
| Per-Unit Cost | Medium (small batches) | Low (economies of scale) | Medium (annealing required) |
| Material Utilization | High (low waste) | Medium (nesting possible) | Low (trimming waste) |
Small batch/customized: Custom metal spinning is most cost-effective (minimal tooling).
Mass production: Stamping offers the best economy (tooling cost amortized).
Deep-cavity parts: Deep drawing from reliable deep drawing suppliers is moderate in cost but requires annealing.

(2) Process Characteristics
| Feature | Mteal Spinning | Stamping | Deep Drawing |
| Part Complexity | High (freeform surfaces) | Medium (structural parts) | Low (deep cavities) |
| Material Thickness | Medium (≤12mm) | Thin (≤6mm) | Thin (≤5mm) |
| Tolerance Control | Medium (skill-dependent) | High (die precision) | Medium (multi-step errors) |
Advantages:
Spinning: Ideal for complex curves & axisymmetric parts(e.g., lighting shades, architectural domes)
Stamping: High precision & efficiency for standardized parts.
Deep Drawing: Specialized for deep cavities (e.g., battery cases, beverage cans).

(3) Production Efficiency
| Metric | Metal Spinning | Stamping | Deep Drawing |
| Production Speed | Slow (single-piece) | Very fast (progressive dies) | Medium (annealing needed) |
| Tooling Change Time | Short (roller adjustment) | Long (die replacement) | Medium (multi-stage) |
| Optimal Batch Size | Small-medium batches | Mass production | Medium-large batches |
Production Recommendations:
<100 pcs: Spinning (quick setup, low tooling cost).
>10,000 pcs: Stamping (high-speed press advantage).
500-5,000 pcs (deep cavities): Deep drawing (balances speed & cost).
