Our factory is a specialized manufacturer of fuel pumps, nozzles, and precision components for fuel injection systems, focusing on high-pressure common rail and traditional engine models. Our core strength lies in the full-process standardized production, providing stable and reliable products to customers both at home and abroad.
We have established a closed-loop control system from raw materials to product delivery. All raw materials are subject to full inspection upon entry, and the processes of precision machining, heat treatment, grinding, assembly, performance testing, and clean packaging are all carried out in accordance with standardized operations. The workshop is equipped with high-precision CNC equipment and specialized tooling, and key processes are subject to online inspection. Defective products will never proceed to the next stage. The entire production process is traceable, and we strictly adhere to process parameters and operation norms to ensure batch consistency.
The factory has passed the quality management system certification. We insist on ensuring quality through standardized processes and serving customers with stable delivery. Our products are compatible with multiple brands of diesel engines and are widely used in construction machinery, commercial vehicles, ships, and other fields. We are a reliable professional manufacturer of fuel pumps and nozzles.

1. Raw material inspection: Use high-quality alloy steel. Conduct batch-by-batch hardness and material tests upon entry to ensure the source is qualified.
2. Precision processing: Perform rough and fine processing using CNC lathes and grinders to ensure dimensional accuracy.
3. Heat treatment strengthening: Conduct quenching and tempering treatments on key components to enhance wear resistance and strength.
4. Ultra-precision grinding and mating of components: Perform mating grinding on precision components such as pistons, oil nozzles, and valve parts to ensure the mating clearance.
5. Cleaning and decontamination: Multiple ultrasonic cleaning processes to remove oil stains and iron filings, ensuring the fuel system is clean.
6. Assembly of final components: Complete the assembly of oil pumps and oil nozzles in a clean environment according to standard procedures.
7. Performance testing: Conduct on-machine tests for flow rate, pressure, sealing performance, and atomization effect. Products that fail the tests will not be released from the factory.
8. Rust prevention, packaging, and storage: Final rust prevention treatment, standardized packaging, and traceable batch information.
