WebSRIM, Structural reaction injection molding. The processing temperature for SRIM is in the range of 60–120°C and the molding pressure is in the range of 5–15 bar. Thus in many respects, the SRIM process is similar to the RTM process. The principal advantage of SRIM is the processing speed. WebThis is where the low-pressure structural foam molding process begins to differ. An inert gas, usually nitrogen, is introduced to the plastic melt prior to injection into the mold. The inert gas expands within the mold cavity. This aids the plastic flow. The gas and the action it produces is so efficient that only a partial short-shot is required.
