This article extends the applications of in‐mold capacitive transducer to packing stage for on‐line part weight prediction and check‐ring failure detection for injection molding. Experiments under various conditions show that the proposed on‐line part weight prediction is robust and effective, which may pave the way for on‐line closed‐loop part weight control. POLYM. ENG.
