PAI breaks into micro-molding.Torlon polyamide-imide (PAI PAI plasminogen activator inhibitor. PAI Plasminogen activator inhibitor, see there ) is being used for the first time in micro injection molding injection molding n. A manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold. . Torlon 4203L is a workhorse work·horse n. 1. Something, such as a machine, that performs dependably under heavy or prolonged use: "the 50-year-old DC-3 ... grade of this viscous viscous /vis·cous/ (vis´kus) sticky or gummy; having a high degree of viscosity. vis·cous adj. 1. Having relatively high resistance to flow. 2. Viscid. , high-temperature material supplied by Solvay Advanced Polymers, Alpharetta, Ga. It is used by RapidWerke in Chicago to mold a 4.2-mg part that replaces metal in a medical machine. The component spins at high rpm under load, generates considerable heat, and requires exceptional strength, wear resistance, and creep resistance, says Scott Herbert, RapidWerke's general manager. It is molded on a Battenfeld Microsystem 50 machine designed for very small parts. This initial success could "open the flood gates" for PAI use in micro-molding, Herbert says.
