Extrusion Screws profile scaling
Screw profile of screw #1 is known. This tool can calculate profile of screw #2. This is a practical method as decision-making tool.
Screw #1
D1 = barrel diameter
Da1 = input core diameter
Dp1 = output core diameter
Screw #2
D2 = barrel diameter
GO!
Da2 = input core diameter
Dp2 = output core diameter
C/R = compression ratio (#1 & #2)
