PHOENIXTM PROVIDES A COMPLETE AUTOMOTIVE PAINT TEMPERATURE MONITORING SOLUTION FOR CQI-12
by hillmedia
Over the last 40 years ‘Thru-process’ temperature profiling has been established as an important and standard method for proving quality assurance of the paint cure process by confirming that the product time at temperature complies with the paint cure schedule.
In addition to product profiling many automotive companies have moved to enhance their quality systems by complying with the coating system assessment CQI-12. This assessment includes comprehensive control , documentation, and quality management of the complete coating process applying to many different coating applications (Process Tables). A critical part of CQI-12 is a strong focus on a pyrometry certification of the oven technology used to cure coatings. Unlike product temperature profiling the focus is given to proving the accuracy and uniformity of the heating technology to provide the target cure temperatures for each coating at defined program settings over the oven working volume. To achieve such pyrometry certification a Temperature Uniformity Survey (TUS) needs to be performed, as applied routinely in the heat treat world in CQI-9. To meet TUS requirements as part of CQI-12 the temperature monitoring system needs to meet specific requirements from a technology, data analysis and reporting perspective.
PhoenixTM offer a comprehensive range of Thru-process monitoring systems designed specifically to address the challenges of automotive paint cure monitoring including TUS to CQI-12.
Thermal View Finishing software has been designed specifically for product profiling in paint applications to convert raw temperature profile data into meaningful information. The software is designed with all the analysis and process documentation tools to fully interpret and communicate paint cure performance. Graphical cure tools including
Phoenix Factor “Index of Cure” or CureChart analysis allow instantaneous accurate cure confirmation directly against paint supplier specifications with ease.
PhoenixTM PTM1520 Epsilon-x intrinsically Safe Thru-process paint cure temperature monitoring system supplied with custom designed SW45 finishing Software with all the necessary analysis and reporting tools to verify the quality of your paint cure process by product temperature profiling.
Temperature Uniformity Analysis Software to meet CQI-12
To perform a TUS to comply with CQI-12, PhoenixTM have developed a software package specifically designed to allow efficient surveying of the oven. At critical TUS temperature levels data logger recorded data can be analyzed to check that at all points on the TUS frame (oven working zone) are within a specified tolerance (Target TUS temperature ± Tolerance) and remain in tolerance for the period of the specified TUS test. Graphical tools and analysis tables allow easy clear data interpretation. Accuracy of data can be maximized through auto application of both data logger and thermocouple correction factors. All analysis and reporting requirements of the CQI-12 are provided by the software to verify full compliance.
For continuous processes the data logger can travel safely, protected by a suitable thermal barrier, with the TUS frame through the process. Live data can be transferred if RF telemetry is used, otherwise, the TUS run can be simply downloaded post run for full TUS analysis and reporting.
For batch oven processes the data logger can be used externally to the oven trailing TUS thermocouples without need for thermal protection. Each thermocouple is fixed to the designated location on the TUS frame positioned in the oven cavity. Live data generated during the run can be viewed in real time in the survey software during the TUS run. Data transfer from data logger to PC can be performed by either a hardwired comms cable, Bluetooth or optional RF telemetry feature.
External PhoenixTM Data logger connected to TUS frame and Thermal View Survey software allowing efficient TUS of an oven processes with compliance with all aspects of CQI-12.
