Hot Runner Monitoring

Avoid mold overmolding and 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.

Hot Runner Monitor

  • Rapid payback period
  • Reduce machine downtime
  • Less repair costs
  • Sustainable investment
  • Injection molding tools can be retrofitted at any time
  • Low-maintenance operation
  • Simple adjustment through 7" touch display
  • Tool and machine-independent operation

Causes of failures can be eliminated by early detection. Possible causes of leakage 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.



To cope with the different sizes of hot runners, we have developed different variants of the Hot Runner Monitor that can cover different numbers of monitoring points.

HRM 08

Hot runner monitoring with up to 8 monitoring points

HRM 16

Hot runner monitoring with up to 16 monitoring points

HRM 32

Hot runner monitoring with up to 32 monitoring points
