The die casting machine Tonnage is indicated by the clamping force of the machine.
Because the die-casting alloy is punched into die casting die in a “high-speed and high-pressure” state, if the die casting machine is not tightly clamped, it will cause a serious flash, causing hidden dangers of work injury; dirty scenes and poor casting quality. Therefore, the die casting machine can provide a 160 ton die force, which is called 160 ton.
The calculation formula for Aluminium Die Casting Tonnage Calculations as follows:
Die-casting machine clamping force (t) = 1.4 * Die Casting parts projected area * specific pressure
Die Casting Parts Projection Area (cm2)
Specific pressure——choose 600 ~ 800 (Bar)
1.4——Modulus, compensating the projected area of runners and slag wells to increase the insurance factor
Generally, How much tonnage machine we should choosing when design die casting mold? it is to select a die casting machine of how much tonnage by calculating the clamping force.
Normally formula: The die casting projection area * Coefficients* Specific pressure / 1000 = clamping force 20cm * 20m = 400cm square large parts clamping force is about: 400 * 600 (casting pressure) / 1000 = 240T
