Hot Runner Leakage


With hot runner monitoring, you check whether the melt, due to leakages, runs over the manifold, nozzles and electronic connections as well as sensors. The leakages are detected at an early stage.


  • Rapid payback period
  • Reduce machine downtime
  • Less repair costs
  • Sustainable investment
  • Simple adjustment through 7" touch display
  • Fast upgrading
  • Low maintenance operation
  • Tool and machine-independent operation

Through the early detection, causes of failures can be remedied. Possible causes of leakages are:

  • Constructional fault
  • Incorrect setting in production
  • Repair services
  • Maintenance services

In areas of possible leakage points, the stainless steel pipes are placed, through which a very low air flow is directed. To establish operational readiness, an air supply of 3...14bar is applied to the Hot Runner Monitor. The machine control is addressed via a potential-free contact in order to interrupt the injection molding process in case of detection.
