PFM Servo

PFM Servo Overview

The PFM Servo (Process Flow Mix) is manufactured to enable multiple metering systems to be used from a single material supply. The metering is carried out by linear actuators operated by a servo motor drive. The use of servo motors enables the systems to hold against pressure making the unit ideal for 2KM’s “Pre-Press” technology which ensures the metering cylinders are loaded with void free materials. The pre-pressurisation also ensures the materials are at the correct application conditions when the dispense cycle commences. Typical applications are the precision dispensing of adhesives and the metering of silicones in a multi machine environment. All systems have point of application control, with cylinder positional feedback giving accurate application information to the data collection systems.
