About the manufacturer
Welcome to Wailey Power Technology
Taizhou Wailey Power Technology Co., Ltd. is a premier, technology-driven manufacturer specializing in premium High-Pressure Fuel Pumps (HPFP) and fuel injection systems. As an industry leader, Wailey proudly served as a co-drafter of China's National Mechanical Industry Standard (Reliability Test Method for Supply Pump Assembly of Gasoline Gasoline Direct Injection Fuel System, Project No. 2021-1153T-JB).
Backed by an IATF 16949:2016 certified quality management system, we maintain a rigorous standard of excellence across 3 advanced high-pressure fuel pump production lines. We integrate top-tier global manufacturing technologies, utilizing elite German precision machinery including Gehring, Peter Wolters, Bahmüller, and Bosch DLC coating systems. This allows us to achieve an extraordinary structural tolerance down to 0.001mm (1 micron), ensuring exceptional reliability and stable pressure regulation under the most demanding driving conditions.
From robust manufacturing to micro-level quality control, Wailey is the trusted strategic manufacturing partner for leading global auto parts distributors, OE brands, and cross-border e-commerce sellers.
Module A
High-Precision Machining Center
We utilize World-Class German CNC grinding and honing machinery to achieve micro-level cylindrical tolerance (up to 0.001mm) and surface roughness of Ra0.1, ensuring zero friction and maximum sealing efficiency.
Gehring Inner Hole Honing
Inner-hole honing supports piston sleeve roundness, sealing accuracy and stable high-pressure fuel delivery.




Peter Wolters Double-Side Grinding
Double-side grinding controls parallelism and flatness for precision pump components under repeated operating load.






Bahmuller Seat Grinding
Seat grinding improves valve seat surface quality, assembly consistency and long-term pressure regulation reliability.
