FFBE Capsule Compression Force Calculator

Instant tablet area, shape factor, and compression force (kN & U.S. tons)

This FFBE Capsule Tablet Calculator helps pharmaceutical engineers instantly calculate plan area, shape factor, and compression force to support accurate press setup and tooling design.

Minor axis (short side) of capsule.
Major axis (long side) of capsule.
Concavity depth of the punch face.
Auto calculates pressure based on Cup Depth lookup table.

Cup Depth to Allowable Pressure Table

Cup Depth (mm)Allowable Pressure (kN/mm²)Concavity Level
0.178 - 0.3050.463 - 0.348Shallow
0.305 - 0.4320.348 - 0.289Standard
0.432 - 0.5590.289 - 0.252Deep
0.559 - 0.6350.252 - 0.235Very Deep

Higher cup depths (deeper concavity) require lower pressures to prevent tooling damage.

Formula assumes standard FFBE capsule plan area. Always validate with your SOPs and press vendor limits.

FAQ

How is FFBE capsule tablet area calculated?

Plan area A = 0.785 × W² + W × (L − W), where W is width (minor axis) and L is length (major axis).

How is pressure automatically calculated?

Pressure is determined using a Cup Depth lookup table. Higher cup depths (deeper concavity) require lower pressures to prevent tooling damage and ensure proper tablet formation.

What is the shape factor?

Shape Factor (S/F) = D ÷ W, where D is cup depth and W is width.

Which units does the calculator output?

Force in kN and U.S. short tons (1 kN ≈ 0.112404 short tons).

What's the difference between S7 and O1/D2 steel?

S7 steel offers 100% force capacity with high toughness. O1/D2 steels provide 90% of S7 capacity but offer different wear characteristics and may be more cost-effective.
