Die Table
Use this Die Chart to estimate tablet weights based on punch type, shape, and maximum fill volume. To get an accurate weight for your formulation, calculate the bulk density of your blend and multiply it by the fill volume shown. This chart is for reference only—real-world testing is still required.
| Die Size (MM) | Min Tablet Weight MG | Max Total Tablet Weight MG | Max Active Ingredient MG | Max Tablet Volume on Single Punch Press (CM3) | Max Tablet Volume With Rotary Press (CM3) |
|---|---|---|---|---|---|
| 4 | 20 | 50 | 33 | 0.25 | 0.24 |
| 6 | 90 | 180 | 120 | 0.57 | 0.53 |

Why It Matters
Choosing the right tooling depends on more than just size—it also depends on how your blend behaves. This chart helps you:
- Estimate tablet weight based on punch shape and volume
- Select tooling that works with your blend’s density
- Prevent issues like over-compression, sticking, or underfilled tablets
To use this chart effectively, calculate the bulk density of your formulation and multiply it by the maximum fill volume listed.
