The Solenoid Plungers shown are custom-made non-standard plungers, which are processed by CNC lathe, and the minimum tolerance can be controlled within 0.02mm. The maximum diameter can be 10 mm and the length can be 30 mm. The details shall be subject to the drawings.

In the automotive industry, solenoid plungers are extensively used in components such as fuel injectors and starter motors. Fuel injectors are responsible for delivering the precise amount of fuel into the combustion chamber of an engine. The solenoid plunger in a fuel injector controls the opening and closing of the nozzle, allowing fuel to be injected at the right time and in the correct quantity. Similarly, in a starter motor, the solenoid plunger engages with the engine’s flywheel to initiate the starting process.

Besides automotive applications, solenoid plungers are also found in telecommunications devices. For example, in a telegraph system, the solenoid plunger is responsible for transmitting signals over long distances. When an electrical current passes through the coil, the plunger moves, striking a metal plate and generating a click sound. This click sound corresponds to a specific Morse code character, thus enabling the transmission of messages.
