Ÿ  Mold platen

Ÿ   Ultimate precision & response

Through the feedback of the high-performance encoder and the pressure sensor, the synchronous servo motor can realize the precise control of the output flow and the pressure by the fast response close-loop control of the RPM and the torque. The repeatability of the output flow and pressure is up to 0.2% and the response time is within 0.05 second.

  

ß Grantway S series has outstanding injection repeatability. The fluctuating RPM under high speed and heavy load is within 1 R / Min. It is a very effective tool for the stability of product quality.

 

 

 

 

ß Grantway S series has a smooth and accurate pressure curve tracking. The precision of steady-state pressure is ±0.5 bar, 0-175 bar in 40 ms

 

The actual pressure performance data shown by pressure transducer accurately follows the set data.

 

 

 

Ÿ   Ultimate energy saving

 

The output of the servo drive system is sensitively altered, according to the actual need of the plastic parts being produced. Driven by a high-precision servo drive, the S series is integrated with an affordable package that guarantees the highest response, highest precision and lowest power consumption at the same time. Compared to variable displacement pump, the S series saves 15% - 50% of electricity and more than 50% of cooling water, and save up to 30% - 80% of electricity, and more than 80% cooling water compared to traditional fixed pump systems.
