Rotary Screw-On Cappers

Request More Information ›

Our freestanding rotary screw-on cappers use Zalkin’s proven Pick and Place technology to apply plastic screw caps to containers at speeds up to 60,000 bph.

With Pick and Place technology, caps are transported single-file via a chute and fed individually into a transfer starwheel with pockets or pegs. The caps are then secured by capping head chucks which then apply the closures using precisely controlled screw-on torque.

The high-performance heart of Zalkin screw-on cappers are the capping heads that deliver reliable, repeatable and accurate closure application.

Zalkin offers multiple capping head options to apply the variety of screw-on closures available on the market:

  • Oscillating magnetic torque application and control (M-Series)
  • Constant magnetic torque application and control (H-Series)
  • Servo driven torque application and control

Zalkin application engineers work closely with customers to select design and configure the capping head technology that is ideally suited to each application and production environment.
