Calculating Intensification Ratio

I was just asked the question…
How can I calculate the intensification ratio of my injection molding machine if I do not know my Hydraulic Cylinder Diameter?
My Response
You can calculate the Intensification Ratio of your machine two ways if you do not know the hydraulic cylinder diameter. The first way to calculate the intensification ratio is to divide the peak plastic injection pressure by the peak hydraulic injection pressure.
The second way to calculate your intensification ratio is to use the machine graph if it has one. The graph usually has lines relating the plastic injection pressure and hydraulic pressure for different screw diameters. Find the line for your screw diameter and divide the peak injection pressure by the hydraulic pressure to calculate the intensification ratio of the machine.
