Inline Thermography
Wittmann Battenfeld’s Inline thermography acts as a quality assurance for materials that are in the hot state. This is achieved by recording the surface temperatures of an injection molded part with a thermographic camera immediately after the ejection process. For this purpose, a robot presents the part to the camera in various positions immediately after ejection. Then the integrated software evaluates the thermal images. Deviations to the ideal original data are calculated and segment-dependent corrections are sent to the cooling circuits of the mold via the WITTMANN FLOWCON flow regulation unit connected to it.
This allows external temperature measurement directly on the ejected component, permanently optimized cycle times through consistent tempering, improvement in production start-up, reduction in start-up scrap, and sustainable quality improvement due to even temperature distribution in the mold. This technology comes in two versions; the open loop version, and the closed loop version which includes mold temperature control.
