HBC-4301A Main Control Case with laptop PC

The Novatech HBC-4301A Hot Bonding Controller is well established as the Worlds most comprehensive and versatile unit on the market.  It has a proven track record, intially having been designed for the Boron Patch Repair carried out by the RAAF (Royal Australian Air Force) and now used by many aerospace organisations for rectification and repair of composite parts.  

A modular system (two main control cases can be linked) it provides the power for up to six zones for the control of heater mats, hot air blowers or infra-red lamps; offering both phase angled and burst fire outputs.  Having two controllable vacuum pumps it can also be used for the double vacuum debulk process.  The unit can be programmed to manage cure cycles (each with up to six stages) by applying the power at the appropriate time to follow a user determined cure profile.  It monitors and records temperature inputs for up to 32 K or J type thermocouples.


  • Independent control of up to 6 zones
  • Inputs for up to 32 K or J type thermocouples
  • Auto selection of the highest temperature in each zone for control
  • Six ramp / soak stages in each cycle
  • Colour coded graphic display using a notebook PC
  • User defined adhesive specifications
  • 99 pre-programmable curing cycles to minimise set up time
  • Hardcopy of all temperature, pressure and alarm data
  • Can monitor and control +ve and -ve pressure
  • Up to 4 internal vacuum pumps, which can be individually controlled and monitored
  • Robust construction
