El Paso, TX emerged as a robust manufacturing hub due to its border proximity with Mexico, featuring IATF 16949 certified facilities focused on automotive and cross-border maquiladora support. Las Vegas, NV shows a mix of global headquarters operations (Westfall Technik) alongside local fabricators primarily serving the gaming, hospitality, and convention industries. Companies were selected based on verified addresses, active websites, and plastic injection molding as a core service offering.
