1. Square Cavity Bottom (No Frame Structure)

Pressure p (kg/cm²): Pressure bearing height a (mm): Cavity side length l (mm): Frame width b (mm): Young’s modulus E (kg/mm²): Allowable deflection d (mm):

Click Calculate to see results

* Recommended: Keep max deflection < 0.1 mm to prevent flash

2. Square Cavity Bottom (Integrated Frame Structure)

Pressure p (kg/cm²): Pressure bearing height a (mm): Young’s modulus E (kg/mm²): Allowable deflection d (mm): Coefficient C:

C value table (based on l/a ratio):
l/a=1.0: C=0.044 | l/a=1.2: C=0.062 | l/a=1.4: C=0.078
l/a=1.6: C=0.090 | l/a=1.8: C=0.102 | l/a=2.0: C=0.111
l/a=3.0: C=0.134 | l/a=4.0: C=0.140 | l/a=5.0: C=0.142

3. Circular Cavity (Frame Structure)

Inner radius r (cavity radius) (mm): Pressure p (kg/cm²): Young’s modulus E (kg/mm²): Poisson’s ratio m: Allowable deflection d (mm):

Click Calculate to see results

4. Support Plate

Forming pressure p (kg/cm²): Pressure bearing height a (mm): Pressure bearing length l (mm): Pressure bearing plate width b (mm): Young’s modulus E (kg/mm²): Allowable deflection d (mm):

Click Calculate to see results

* Support blocks should be as short as possible
