Abstract
- A robust on-line detection system for estimating the gate freezing-off time, which is useful for monitoring and control of injection molding, was developed based on an analysis of the correlation changes around the gate freeze-off time, as reflected in the changes of the screw movement and nozzle pressure (NP). Experiments showed that the gate freezing-off time can be accurately detected under different molding conditions. POLYM. ENG. SCI., 45:33-41, 2005. [c] 2004 Society of Plastics Engineers<br />INTRODUCTION In injection molding, packing-holding commences at the end of filling. Additional polymer is packed into the mold at high pressure to compensate for the material shrinkage associated with solidification. [...]
