Pressing blood bags with Exlar servo actuator
For sealing of blood bags the Exlar GSX40, GSX 50 and GSX60 servoactuators are applied. Compressive forces run the process up to 70 kN. There has been chosen for an electric actuator as a replacement of a pneumatic or hydraulic cylinder, because of the high reproducibility. Through a load cell, the force is measured. Because the actuator is provided with a roller screw, the lifetime is high in spite of the high duty cycle.
