Comparing to traditional ball-screw actuators, the roller-screw Kinegge units are much more durable an can be operated much longer. Thanks to special hardening technologies of roller-screws, high-quality of materials processing and robust design, Kinegge actuators withstand higher loads during longer time. Overall lifetime can be increased up to several time compared to ball screw solutions.

Kinegge engineers were faced with the task of creating an electric valve actuator that does not require a significant increase in the cavity for its placement in the mold compared to hydraulic cylinders of the same force. To achieve this goal, Kinegge engineers have developed a unique design of a compact and lightweight direct drive, mounted on the hot runner manifold coaxially with the valve gate.

Thanks to a more powerful motor and a smaller transmission ratio, the Kinegge roller-screw actuator can be used for higher loads, expanding the range of operating pressures of the dispenser.

High force range combined with a long stroke of 190 mm allows to use DA99-D22 actuator in a variety of applications, which allows to save costs on the necessity to have different models for different dosing units and shot meter sizes and volumes.

Kinegge actuators are equipped with a digital memory containing the serial number and information about the feedback sensor and actuator parameters, that are automatically read by the customer's control system. This makes it possible to connect or replace the actuators without the need to manually configure the control system.

Thanks to the placement of the grease adding port on the front flange, Kinegge actuators provided the ability to add lubricant regardless of the position of the dispenser rod. With this feature it is possible to conduct maintenance at any stage of the production cycle and without any preparation operations.
