reaction injection moulding (RIM)

https://doi.org/10.1351/goldbook.RT07628
reactive polymer processing that produces polymer monoliths by low-pressure injection and mixing of low-viscosity precursors into moulds.
Note:
Reaction injection moulding commonly uses two-component precursors that produce polymer networks after mixing.
