HSP sensor against plastics leakage

e.g. on the injection moulding nozzle, mould inlets, etc.

In common production of plastic parts on injection moulding machines leakage occurs between the injection moulding unit and the mould resulting in plastic material leakage. The plastic can go along the nozzle all the way down to the heating belt and cover even the entire length of the barrel and all heating belts and cause significant problems and damage. 

HSP sensor against leaking plastics

Installing the HSP sensor prevents the following damage:

  • soiling of the barrel  
  • devaluation of heating belts
  • devaluation of thermal insulation covers (if installed on the machine)
  • machine downtime for cleaning and exchanging heating belts when the machine cannot produce

Installation of the HSP sensor:

The sensor checkpoint is installed on the machine nozzle and detects motion of plastic on the nozzle surface.

Evaluating sensor part can be installed anywhere on the machine. HSP sensor uses a compressed air, which must be connected,to the sensor. Thanks to the use of the ejector, the sensor creates vacuum in the monitored area. When the value is changed, the sensor signals an error and the machine stops (after finishing the product).

Depending on the used variant, the HSP sensor can be equipped with an evaluation panel with light and sound signalling.

The installation of the HSP sensor against plastic leakage  is universal for all types of machines.

Thanks to the HSP sensor installation, you can achieve significant financial savings for:

  • purchase of new heating belts and thermal insulation covers
  • time spent on cleaning, dismounting and assembling new heating belts
  • downtime during machine repairs

HSP Sensor against plastic leakage is available in three variants:

HSP-S

basic variant without evaluation panel

HSP-M

variant with evaluation panel

HSP-C

variant with evaluation panel and timer
