Teaser Infrared Image - The Answer

You guys were getting warm with those guesses, but you weren’t quite there…

Answer: This week’s teaser infrared image is of a plastic case part for a multimeter—minutes after it has been ejected from the molding equipment! While it is often not possible to gain any truly useful information with a thermal imager when you look at a reflective, low-emissivity, metal surfaces on a plastic injection molding machine, it is sometimes useful to look at the parts as they come out. The heat that you see on the parts can be correlated to the similar areas on the mold.Ā  Watching the parts cool is also useful, and helps mechanical and manufacturing engineers fine tune their designs and equipment for best results.
