Molding process.The reaction assisted molding process (RAMP) borrows heavily from reaction injection molding Reaction injection molding OR RIM Molding is similar to injection molding except that a reaction occurs within the mold. The process uses thermoset polymers (commonly polyurethane) instead of thermoplastic polymers used in standard injection molding. (RIM), and is based on low pressure and low temperature dispensing of polyurethanes (unlike RIM, which is based on high pressure and temperature). The RAMP technique precisely positions computer chips and electronic components within a mold between two sheets of PVC PVC: see polyvinyl chloride. PVC in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. or polycarbonate A category of plastic materials used to make a myriad of products, including CDs and CD-ROMs. film, after which a polyurethane mixture is injected at low temperature and low pressure to completely immerse im·merse tr.v. im·mersed, im·mers·ing, im·mers·es 1.
