SHAKTI Lab Press Control System Overview

Tablet Press Control System works force based press control system that utilizes feedback of measured compression peak force value to continuously adjust die fill level and thus compression force. It establishes and maintains target compression force feed back control scheme. The press control system automatically rejects tablets that fall outside of the designated compression force limits. HMI – PLC system provide features like
