1. What is Hydraulic Press Tonnage?

Definition: Hydraulic press tonnage measures the force a press can exert, calculated from system pressure and piston area.

Purpose: This calculation helps determine if a hydraulic press has sufficient force for metal forming, molding, or other industrial applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tonnage (tons)
• \( P \) — Hydraulic pressure (psi)
• \( A \) — Piston area (square inches)

Explanation: The formula converts pounds-force (from psi × in²) to tons by dividing by 2000 lbs/ton.

3. Importance of Tonnage Calculation

Details: Proper tonnage calculation ensures the press can handle the required workload without overloading the system.

4. Using the Calculator

Tips: Enter the system pressure in psi and piston area in square inches. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 2000?
A: There are 2000 pounds in a ton, so we convert from pounds-force to tons.

Q2: How do I find piston area?
A: For circular pistons, use \( A = \pi \times r^2 \) where r is the piston radius.

Q3: What's typical hydraulic pressure?
A: Most industrial systems operate between 1500-3000 psi, but check your specific equipment.

Q4: Does this account for efficiency losses?
A: No, consider multiplying the result by 0.9 for typical 90% system efficiency.

Q5: Can I use this for multiple pistons?
A: Yes, either sum all piston areas or calculate each cylinder separately and sum the tonnage.
