Advantages of Servo-Actuated Molds for Manufacturing Medical Devices

Electric servo motors are rapidly replacing mechanical, hydraulic, and pneumatic actuation systems in plastic injection molds, particularly those used in medical cleanrooms, where clean, precise mold actuation can make a significant difference to part quality. In general, servo motors are becoming more common in medical injection molding work cells, thanks to the growing installed base of electric injection molding machines. Already, electric machines represent about half of the total injection molding machines sold annually in the United States, and the percentage is even higher in Japan. This trend, coupled with more-frequent use of servo-actuated robots in injection molding and innovations in electric injection molding machinery, has brought servos to the forefront.
