Punch Tip Force Guide
Maximum compression forces by punch material
(kN & U.S. tons)
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.
FAQ
How are maximum punch forces determined?
Maximum forces are based on material properties, heat treatment, punch geometry, and safety factors. They represent limits under ideal conditions with proper tooling maintenance.
What happens if I exceed the maximum force?
Exceeding maximum force can cause punch tip fracture, premature wear, tooling damage, and potential safety hazards. Always operate within recommended limits.
Which material is best for high-force applications?
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.
How do I choose the right punch material?
Consider compression force requirements, tablet abrasiveness, corrosion resistance needs, and production volume. Consult with tooling suppliers for specific applications.
Are these values universal for all punch sizes?
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.
