Pressure measurement system – optimises the filling process

Let’s start with the main features:

  • Compact add-on device
  • for 4 to 32 zones in steps of 4
  • Additional analogue input 0-10V
  • Operation via TP hot runner control devices
  • Flexible visualisation

A winner in combination with the hot runner controller

Since 2018 in our assortment the pressure measurement system DMS boasts high filling study precision and enables optimum cycle times during the filling process. The automatic detection of good / bad parts ensures a high degree of automation. The pressure curve indicates whether the temperature for melting the raw material should be increased or reduced in order to achieve an optimised filling of the cavity. The settings for the mould cavity pressure are stored in just one mould data set. The visualisation occurs via the connected TP temperature controller. DMS can be used irrespective of the sensor brand.
