Reactive injection moulding
WebThe difference between RIM and injection molding Injection molding is the process of forcing melted plastic into a mold. With reaction injection molding, two liquid components (isocyanate and polyol) are mixed in a high- or low- pressure mixing head and pumped into a mold. The reaction occurs in the mold, resulting in a polyurethane part. WebReaction Injection Molding (RIM) is a low molding pressure process for production of complex plastic parts directly from low viscosity monomers or oligomers. Two or more reactive streams A and B are combined by impingement mixing in a self -cleaning mix head (10 to 20 MPa) prior to enter the mold. Mold pressures are very low (less than 1 MPa).

WebReaction Injection Molding WebIn the RRIM process, two or more reactive resins are metered and impingement-mixed under high pressure to form a thermosetting polymer, injected into a mold, and then cured. RRIM composites have a number of processing advantages including very fast cycle time, low labor, low mold clamping pressure and low scrap rate.
WebApr 15, 2011 · In simple terms, RIM is the result of a reaction between isocyanate and polyol, two liquid components, as they are injected into a mould at particularly low pressure. These two components are low-viscosity liquids and mix together as they flow into the mould. The polyurethane is then formed in the tool cavity as the temperature and pressure at ...
