how screw design affects processing nov 20

injection screw that is 20/1 will have 20 flights. Most injection screws will be between 17/1 and 24/1. OEMs will often design a press to accept a grouping of injection units that allow for flexibility in molding. As the screw diameter changes in that grouping so does the L/D ratio. The L/D ratio is a fixed ratio.
