The automotive industry requires millions of complex parts each year, components designed for everything from electrical systems to vehicle frames. A particularly common application for precision metal stampings is terminals and electrical connectors, which are often two-part socket and tab designs that require extreme durability. In addition, plastic injection mold parts are used very frequently in the automotive industry, due to their innate design flexibility, but also their high durability and service life, which can be perfectly combined with metal stamped parts.

The main role of automotive connectors is to connect different circuits in the vehicle to form a whole, is a bridge for current or signal transmission and exchange between electronic systems and equipment, and is the most basic and necessary component of the car, which is responsible for transmitting and controlling electrical signals, so that the various functional systems in the car (e.g., engine management, seating adjustment, and equipment display, etc.) are able to work properly.
