Pneumatic Plunger Mechanism

Low friction

The new floating plunger concept maintains the alignment after first self-centering to the neckring, reduces radial load on the piston rod, wear on neck ring and positioner.

  • Improved verticality of the plunger
  • New design allows more repeatable and smoother piston movement
Advanced cooling

Increased plunger cooling capacity with individual and independent cooling air exhaust per cavity.

  • High speed operation
  • Improved forming quality
Advanced technology and material

Advanced technology of components and material allows to increase enduring reliability of the mechanism and easy maintenance.

  • Low friction of piston seals reduced air pressure for plunger up
  • Improved lubrification of the plunger mechanism
  • Possibility to apply a stroke sensor
  • Easy access to clean dirt in the plunger
Light weight design

The engineering of the mechanism has dramatically reduced the weight.

  • Granting easier plunger mechanism replacement
