VPower R 120 – 160 t

The flexible VPower R rotary table machine is available with clamping force sizes from 120 t to 160 t and rotary table diameters of 1300mm and 1600 mm. It is characterized above all by its high degree of efficiency, its fast changeover capability and its maximum mold protection thanks to the UNIFORCE compensation platen system. The machines of the VPower R series can be optimally combined with the WITTMANN production cell.

Efficient and convertable

 
The VPower R stands for highest precision, flexibility, efficiency and mold protection. It is not only designed for flexible adjustment to any given manufacturing task, but also allows for changes between different manufacturing processes involving only short changeover times. Furthermore the powerful control unit UNILOG B8 offers numerous possibilities for process monitoring and documentation. Optional, as an alternative to the standard drive, a direct drive by means of a servo motor is offered, which allows for simultaneous plasticizing.
This machine series has a smaller footprint than its predecessors and is easy to operate due to its low and ergonomic working height. Particularly noteworthy is the UNIFORCE compensation platen system, which ensures a previously unattainable even and wear reducing transmission of force between the horizontal beams and the mold clamping area.

 

Advantages:

  • Easy access to the media supply connections below the rotary table
  • A rotary table system without a central tie-bar allows for unhindered production.
  • Shortest rotation times and highest precision of positioning of the rotary tables
  • Easy conversion of the injection unit between horizontal and vertical Position
  • UNIFORCE compensation platen system for optimal force distribution
