Nylon parts are made from polyamide (PA), commonly called nylon. Injection molding, extrusion, or machining shapes them—PA6, PA66 are common types. Glass fiber adds strength when needed. These parts have good toughness, resisting impact and wear with self-lubrication. They resist chemicals and weigh less than metal. They’re easy to process at low cost. They serve gears, bearings, gaskets, and auto accessories. They work for electronic insulators and hardware tools. They’re cost-effective wear-resistant engineering plastic parts.
