Silicone vs. Metal Dies
Here is a short answer
When selecting a die material, use the following guideline
| Rigid Substrate | Flexible, rubber die |
| Flexible Substrate | Rigid, metal die |
Of course, there are many additional considerations to take into account. Here is a much more detailed comparison of silicone and metal dies
