Research overview:
The behavior of melt-flowing plastics inside a mold has been observed so far only by the short-shot method which is an objective method. However undesirable phenomena on injection molded products such as jetting, flow-marks, residual stress, etc., are relative to the flow behavior during the flowing, packing and cooling processes. Therefore a real-time measuring in a mold is thought to be only one possible method to reveal the phenomena clearly. This project aims to establish a new observation system of flow behavior within a mold cavity by using a glass-inserted metal mold and a compact CCD camera with strobe units. We are also going to construct an analyzing system of plastics flow on the basis of the above method and the image processing technique.
