You can use some formula, to work out the clamping force. Formula1:clamping force=clamping force constant Kp* product area of contour S(cm^2)Kp empirical value: PS/PE/PP:0.32,ABS:0.30-0.48,PA:0.64-0.72,POM:0.64-0.72. Add Glass Fiber:0.64-0.72.Other molding plastic material:0.64-0.8
For example: If a product's parting surface area of contour is 410cm2, materialis PE, Work out the necessary clamping force.
According to the formula above:p=Kp*S=0.32*410=131.2Ton. So we should choose 150Ton injection machine.
