Detect a PUR overflow before it occurs

Moldsonics erkennt die PUR-Fließfront berührungslos durch den Werkzeugstahl — ohne Sensorabdrücke und mit <5 ms Detektionszeit.

With Moldsonics sensor technology, it is possible for the first time to detect the PUR flow front without contact - a real benefit for our customers in terms of process reliability and surface quality.

The challenge

During PUR flooding, the flow front moves very quickly and is difficult to detect reliably. At the same time, no sensor imprints may occur on visible components - a combination that pushes conventional measuring methods to their limits.

Solution

Moldsonics detects the PUR flow front non-contact through the tool steel.
This allows the vent needle to be closed precisely—without coming into contact with the surface.

Result

  •  No sensor fingerprints
  • < 5 ms Detektionszeit
  • No uncontrolled PUR leaks at the end of the flow path
  • Greater process reliability for visible components
