Model PBX Pneumatic Bonders for Bonding Rubber     O-Rings with Standard Diameter or Special Shaped Solid Cross Sections that require Time and Temperature Controls and Die Set Changes for Additional Sizes and Shapes.

  • The PBX Models are benchtop units consisting of a pneumatic vertical press controlled by dual air cylinders and activated by use of a foot pedal thus allowing for hands-free (2-hand) positioning of rubber cord stock.
  • Adjustable air pressure regulator permits a controlled squeeze of the rubber O-Ring cord or extrusion, compensating for any cord stock cross-sectional deviation. Air pressure can be adjusted up to 100 psi, allowing the process squeeze to be regulated based upon the durometer and outside diameter/profile shape of the rubber cord.
  • PBX Bonders contain adjustable time and temperature controls and are available in 2 Models: ANALOG (PBX700A) or DIGITAL (PBX800D) Time and Temperature Controls.
  • (2) heaters; one in each top and bottom platen. Temperature control range of 0 to 400° F (204° C)
  • Both Models contain adjustable timers for automatic separation of the die-sets; ensuring that proper bonding time is maintained.
  • Changeable die set design. (The added "X" in our part numbers indicates models with die change compatibility). Quick, 2-minute, die changes (8 screws)
