Structural Reaction Injection Moulding

The Process

S-RIM is the next step with respect to the traditional low pressure RTM. A complete composite part can be obtained in a time ranging from less than 2 to 5 minutes, depending on the reaction time of the chemical and on the various process parameters. S-RIM consists in the injection of a multi-component mixed thermoset PU matrix into a closed mould in which a dry reinforcement preform has been previously placed, and where vacuum has been applied. After polymerization, the mould is opened and the finished part is extracted.

Features and advantages

This process allows to obtain very resistant structural and semi-structural parts by combining reinforcement and matrix directly during injection phase. The  high pressure impregnation allows to decrease raw material costs avoiding wastes.

This process is suitable for 3D geometries and long fiber reinforcement.
