Conductive sensors

In casting processes, they would be ideally be placed at the interface between matter and mold. For robustness and non-marking reasons, we place them inside the tool. Value obtained in the tool approaches thermal gradient between the processed material and mold, giving thereby access to materials developments and thermally-linked changes during processing.

Applications: Characterization processes like :

• • Injection of thermoplastic: flow front detection, detection of defects like incomplete parts or changes in melt index, over molding monitoring, cooling time

  • Injection of thermoset, BMC: cure monitoring, abnormal injection detection (over-heating)

  • Compression of thermoset, SMC, C-RTM: cure monitoring and control

  • Resin Transfer Molding, RTM, Infusion: flow front detection, cure monitoring

  • Thermoplastic Compression, GMT, Stamping: heat transfer and cooling control

  • Thermoforming: control of cooling, variations in thickness in areas of high strain

  • Pultrusion: control and steering of the cooking, optimizing speed line

  • Extrusion: controlling the process stability

And of course, many other possibilities (metallic casting)...
