This Punch Tip Force Guide helps pharmaceutical engineers determine maximum allowable compression forces based on punch material specifications to prevent tooling damage and ensure optimal tablet production.
| Material | Max Force (kN) | Max Force (Tons) | Characteristics |
|---|---|---|---|
| S7 / SL Steel | 48.1 | 4.9 | High toughness, shock resistant |
| 440C / D2 Steel | 35.3 | 3.6 | Good wear resistance, corrosion resistant |
| M340 Steel | 35.3 | 3.6 | Excellent toughness, high impact strength |
| K340 / DC53 Steel | 35.1 | 3.5 | Superior wear resistance, dimensional stability |
Maximum forces are based on material properties, heat treatment, punch geometry, and safety factors. They represent limits under ideal conditions with proper tooling maintenance.
Exceeding maximum force can cause punch tip fracture, premature wear, tooling damage, and potential safety hazards. Always operate within recommended limits.
S7/SL steel offers the highest force capacity (48.1 kN) due to its superior toughness and shock resistance, making it ideal for hard-to-compress formulations.
Consider compression force requirements, tablet abrasiveness, corrosion resistance needs, and production volume. Consult with tooling suppliers for specific applications.
These values are general guidelines. Actual limits may vary based on punch diameter, tip geometry, and specific manufacturer specifications. Always verify with your tooling supplier.
