📌Design：Engineers create detailed plans for the fuel injector, considering factors like flow rates, spray patterns, and compatibility with the engine.

📌 Material：Selection: High-quality materials, often heat-resistant alloys or stainless steel, are chosen for durability and performance.

📌 Machining: Precision machining techniques are employed to shape injector components with tight tolerances, using CNC (Computer Numerical Control) machines for accuracy.

📌 Assembly: Components, including nozzles, valves, and solenoids, are assembled by skilled technicians in a controlled environment to prevent contamination.

📌 Calibration: The assembled injectors undergo calibration to ensure precise fuel delivery, adjusting factors like spray angle and flow rate according to design specifications.

📌 Testing: Rigorous testing, often using specialized equipment, is conducted to verify injector performance, including leak tests, flow rate tests, and response time assessments.
