Conductive sensors quantify heat transfer by conduction in solids.
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 mould, giving thereby access to materials developments and thermally-linked changes during processing.Applications
: Characterization processes like :
- Injection: flow front detection, detection of defects like incomplete parts or changes in melt index.
- Injection of thermosets, BMC: detection of the end of cooking, abnormal injection (over-heating).
- Thermosetting Compression, SMC: Curing monitoring and control.
- Resin Transfer Molding, RTM: Flow front detection, cure monitoring
- Thermoplastic Compression, GMT: 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...
