The control capacity and flexibility of the injection compression molding technique is significantly greater than that of conventional injection molding. If compression starts before complete filling, the process can be called injection-charged compression molding (ICCM). This article investigates the effects of the ICCM process on moldability and part quality. Effects of compression-related parameters, including delay speed, pressure, time, and distance, are also investigated. ICCM extends the moldable area with an expanded cavity during short-shot filling. The process improves dimensional accuracy in the lateral direction. However, surface conformity to the cavity is not better than conventional injection molding due to a significant orientation difference in injection- and compression-filled zones. The good part quality can be obtained with short delay, long compression distance, low pressure, and proper compression time.
