Reaction injection molding - Wikipedia
Then the mixture is injected under lower pressure into a mold. The mixture is allowed to sit in the mold long enough for it to expand and cure. If reinforcing agents are added to the mixture then the process is known as reinforced reaction injection molding (RRIM). Common reinforcing agents include glass fibers and mica. This process is usually used to produce rigid foam [PDF]

The process of injection moulding explained
Sep 08, 2014An injection moulding machine consists of a material hopper, a plunger and a heating barrel. The machine works to exert pressure and secure the mould in place during the injection process, and the type of machine that is used will be determined by the type of part being moulded and the material being used. For example, large parts and stiff[PDF]

Structural Foam Molding • A variation of the injection molding process, developed for applications where stiffness is a primary concern, and particularly for large structural parts. • Parts consist of a rigid, closed-cellular core surrounded by a continuous, solid skin. • The polymer melt contains a dissolved inert gas; most
