Determining Intensification Ratio Using Specifications...

I was asked this question during an on-site visit earlier this week...

I know this machine is rated with a maximum injection pressure of 38,000psi, but I am not sure how to convert this to an intensification ratio.

note: The intensification ratio is a factor which is used to convert the hydraulic pressure being applied to the hydraulic injection cylinders into the actual pressure being applied to the polymer melt at the front of the screw.
My Response
If you know the maximum plastic pressure (Pp-max) along with the maximum hydraulic pressure (Ph-max) for your machine, you can estimate the intensification ratio (Ri) for your machine. /  = 

Pp-max / Ph-max = Ri
