Inline thermal imager identifies defects in injection-moulded parts

Working with Kunststoff-Zentrum SKZ KTT in Germany, sensor manufacturer Micro-Epsilon has developed an inline, non-contact temperature monitoring system for injection moulding machine quality control.
Micro-Epsilon's camera is uses the thermal radiation from the workpiece to detect not only visual faults but also hidden defects in the material. SKZ's software visualises the workpiece and compares it to an infrared reference image, and the system enables manufacturers to automatically remove defective parts. Furthermore, Micro-Epsilon says it ensures rapid and secure machine changeovers, since newly produced parts can be evaluated immediately production restarts. Powered and operated via a USB 2.0 interface, the development, dubbed thermoImager TIM 160 comes with software that covers configuration, as well as enabling the real time capture and storage of images or video of an event for slow motion playback.
