DA 99

Electromechanical servo actuator DA99 is a good solution for microinjection molding for several reasons. First of all, the robust design of roller-screw provides a very long lifetime. Secondly, it provides very precise motion that enables accurate positioning of the injection plunger and ability to manufacture thing-walled parts of 0.02 mm thickness, which is not possible when using hydraulic cylinders. Lastly, it is much simpler to set up and make retuning for various working modes and allows more sophisticated duty cycle settings.

1. Long lifetime
Robust design of the actuator and high-quality of Diakont roller-screw provide long lifetime even in demanding requirements of duty cycles for plastic injection.

2.Precision of injection
Highly accurate position of the actuator rod allows to manufacture thin-walled parts of 0.02 mm thickness, which is not possible when using hydraulic solutions.

3.Absolute encoder of high resolution
DA99 is equipped with high resolution encoder which allows for even higher precision of motion and high level of control over its operation.

4.Ease of setup and flexibility of operation
Electromechanical actuators allow easy retuning of working modes and higher flexibility and choice of working cycles to satisfy various requirements of the customers.
