Abstract
En 中文
As the injection molding industry has grown, so has the use of injection molding simulation software. While design groups have utilized the abilities of simulation software, its use is often underutilized by process engineers. To expand the application of simulation software to manufacturing groups, this work focuses on developing injection molding process windows through the predictions of simulation software. Process windows are a set of operating conditions and limits that allow for the manufacturing of an acceptable injection molded part. A methodology was developed for the construction of process windows by testing numerous combinations of controllable process variables in the filling and packing stage of the injection molding process. The methodology additionally allows for modifications so that the process can be tailored to each manufacturer’s desired product performance measures. Each process window developed was experimentally validated showing that each combination of controllable process variables represented by the process window resulted in an acceptable part. The experimental validation of the process windows establishes confidence in the software’s ability to aid manufacturing groups to successfully run their operations.
