Fuel Injection System
Fuel injection systems encompass the fuel rail and fuel injectors mounted above the intake manifold in combustion engine vehicles. A fuel pump sends the fuel to the engine bay, and is then injected into the intake manifold by the injector—either directly, or mixed with air before the intake stroke.
Interplex customizes both electrical and mechanical solutions for fuel injection systems; for example, mounting accessories, covers and lids, terminals, and sensor connectors.

Mounting Accessories and Guide Rails/Levers
Present in various locations throughout a car and with various end applications, examples of mounting accessories that Interplex produces include precision stamped washers and flanges; mounting clips that withstand harsh environments under the hood of a car; guide rails, slider trays and levers that provide structural integrity for power roof, window, and trunk mechanisms; and sturdy mounting brackets for radar control modules and cameras.
No matter the thickness, shape or form you need, we can precision stamp these accessories to your desired thickness and bend them to the required shapes, all while maintaining the required structural integrity for the end application.Our precision stamping processes are complemented with a comprehensive range of value-added processes such as clinch nut stacking, heat treatment, riveting and welding.

Press-Fit
Interplex’s Press-Fit technology establishes solderless electro-mechanical connections with plated-through holes on printed circuit boards. These repeatable and reliable connection joints perform well even in harsh environments, and can manifest in a myriad of forms such as connector headers and customized overmolded electronic enclosures.
Extending across a multitude of industries, possible end applications include power distribution, actuator controls, automotive body control modules, solar panels, watches, passenger comfort and infotainment switches, airbag ECU safety solutions, and much more.
Interplex offers a wide spectrum of options: Choose from different materials, plating options, and even designs. From the low force eye-of-the-needle available in various sizes, to the hybrid MiniPLX perfect for high density signal and power applications, and even customizable options for dual-ended/SMT/IDC integrated Press-Fits.
