Hot Press & Ram Cylinder

Measure the ram (piston) diameter with a caliper, or wrap a tape round the ram to get the circumference.
Diameter = Circumference ÷ 3.14.
1 ram area = 3.14 × d² ÷ 4, and Total Ram Area = 1 ram area × number of rams.

📋 Technical Specification & Plywood Size Chart

Linked to the details above: values = ply area × specific pressure ÷ ram area. Red = above max working pressure.

📋 Plywood Size Chart – Dial Pressure in MPa

Same chart as above in MPa (MPa = rounded kg/cm² ÷ 10.197). Red = above max working pressure.
