“…Fluid assisted injection molding technology, including gas assisted injection molding1–4 and water assisted injection molding,5–9 has become an important polymer process, due to the light weight of molded parts, relatively lower resin cost per part, faster cycle time, and its flexibility in the design and manufacture of plastic products. In fluid assisted injection molding, the mold cavity is partially filled with the polymer melt followed by the injection of gas or water into the core of the polymer melt.…”

This study aims to examine the morphological development in fluid assisted injection molded high density polyethylene (HDPE)/polycarbonate (PC) blends. Samples for microscopic observation were prepared by an 80‐ton injection‐molding machine equipped with a tube cavity and with both gas and water injection units. It was observed that the shape and size of the dispersed phase depended on the position both across the part thickness and along the flow direction. Water molded parts with a smaller PC particle distribution than gas. Additionally, high fluid pressures were found to mold parts with a smaller PC particle distribution. For both gas and water assisted injection molding, small and large particles coexisted in the skin and subskin layers, indicating that both coalescence and breakup of the dispersed phase occurred in that layer.magnified image

“…Water assisted injection molding has advantages over gas assisted injection molding (Turng, 1993;Chen et al, 1995;Liu, 2009) in that it requires a shorter cycle time to successfully mold a part ( Fig. 5) (Liu and Chen, 2003), mainly due to the higher cooling capacity of the water during the molding pro-cess especially for thicker parts.…”

Water assisted injection molding technology has become one of the most important methods to manufacture hollow plastic parts in recent years, due to its light weight, relatively lower resin cost per part and faster cycle time. This report aims to present a review of the development and progress of the water assisted injection molding technology. The tooling used for the process is introduced. The interaction between the assisting water and the polymer melt during molding is discussed, and insight into the penetration behaviors of the fluid is summarized. In addition, comparisons have been made between the gas-assisted injection molding and water assisted injection molding processes.
