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.
