Rotary Platen Dynamics in Hydraulic Molding Presses

A practical treatment of rotational inertia, hydraulic flow and torque, and proximity-sensor-gated soft-stop tuning for high-inertia rotary platen molding presses.

Document overview

Rotary platen molding presses couple a high-inertia rotating mass to a hydraulic drive. This paper separates the roles of flow and pressure, relates them to rotational dynamics, and explains how proximity feedback can initiate a controlled deceleration that reduces shock, protects tooling, and improves final alignment.
