A downloadable PDF FIle from Mikron Infrared describes the use of IR Thermometers in manufacturing operations using thermoformed plastic sheet materials.
Thermoforming is the process of using heating elements and/or cooling elements to mold or shape
some type of material. Typically this material will be a type of plastic.
The process follows a path from extrusion to molding. Most thermoforming companies will use extrusion machines to extrude the plastic, which then will be pulled into an oven and heated until it reaches a certain temperature.
Once this temperature has been obtained the plastic is moved out of the oven into a cooling and molding zone. Usually the machine runs on a timer so the temperature of the plastic varies and is inconsistent within the oven.
The plastic is molded and cooled either by water-cooling or air-cooling. Most applications use water-cooling either sprayed onto the plastic or pushed through the metal mold.
Finally, the plastic is moved to a cutting zone where the shapes are cut out of the plastic. This can be done either manually or automatically as well.
This application has a couple of different sections that are ideal for infrared pyrometers and imaging. (more…)

Large Area Calibrators with Radiometric Calibration Traceability From -15 °C to 500 °C!
American Flats UT, USA — The new blackbody calibrators being offered by Hart Scientific are a breath of fresh air.
They come with radiometric calibration traceability built-in and the sales web page on the Hart Scientific website is exceptionally informative.
So, too are the online and free downloadable PDF files of the Users Manual (in 7 additional languages), the Technical Manuals and an Applications Note entitled “IR Calibration 101″!
Not only are they exceptionally complete and well-written, in our opinion, they set a new benchmark for their competitors, Ametek-Land and Mikron Infrared in the industrial and scientific blackbody arena.
It looks like Fluke has really done its homework and executed a well-reasoned product development plan.
Kudos to the people at Hart Scientific and Fluke!
NOTE:Much of the same information can be found on the Fluke Corporation website for obvious reasons.
Orlando FL, USA — A paper at the 30th ThermoSense Conference (ThermoSense XXX) entitled “Thermographic nondestructive testing using inductive thermal excitation” by Morteza Safai of the Boeing Company. It was presented on March 20th described an innovative method for locating unbonded metallic fiber defects embedded several millimeters deep in a non-conductive plastic matrix.
The technique utilizes a transient heating source consists of a low power, portable “wand” to induce a localized small temperature rise of only a few degrees within the metallic structure. A relatively low cost infrared Thermal Imager is used as a monitor to show the resultant thermal transients. Unconnected metal fibers show up as brilliant, short time duration hot spots.
The inspector can then zoom in and precisely localize the defect location quickly and easily.
Developed as a means to locate and possibly quantify incomplete repairs in composite aircraft skins, this technique may have uses in several other applications, including those with partially conductive plastic materials and possibly even a means to locate defects and thin spots in thin films of conductive materials.
Congratulations to Morteza Safai for a smart and significant contribution to non-contact NDT!
