Calculate the Dial pressure of Hot Press which will be given based on plywood size. Which will be calculated as follows

Calculate the area of the plywood

Assembly Plywood Size- 99 Inch (251 cm ) X 50 Inch (127 cm) =31877 cm2

Pressure Controller
Dial Pressure Calculator with Chart

Dial Pressure Calculator

Dial Pressure = Ply Area (cm) × Specific Pressure (Kg) Ram Area (kg/cm²)

Ply Area = Length × Width

Example:

Dial Pressure = 127 (cm) × 251 (cm) × 11 (Kg) 2512 (kg/cm²)

Dial Pressure = 140 (kg/cm²)

Fill Details & Calculate
