Polyurethane Injection Molding and Other Chemical Processes that Create Microcellular Prototypes

Written by admin on . Posted in Encapsulation, Overmolding process

Polyurethane injection molding creates microcellular parts and pieces needed for automobiles, construction, and other industries. Sometimes these are prototypes or other items that may come from polyurethane Reaction Injection Molding (RIM) processed materials. With the different materials used in this process, any of them may be cells as small as one-thousandth of an inch.

Polyurethane Injection Molding Process for Microcellular Systems

Many different processes are able to produce these prototypes and microcellular items. It may be RIM or even the overmolding process where there is a combination of two liquid components. In either one of these, there may be a combination of polyurethane, polyureas, polyisocyanurates, polyester, polyphenol, polyepoxide, and nylon 6. It could be the creation of a fiber mesh or a foamed material, though some of the thicker ones are solids used for walls in construction.
