FROM COMPONENTS TO CONNECTIONS
Experience built
on the factory floor.
HAOLI was founded in 2004 in Ruian, Zhejiang. We began with automotive components, including driveshaft-related stamped parts, and have continued to develop our sensor and component portfolio.
Our factory floor area is approximately 35,000 m². Oxygen and NOx sensors are central to our range, alongside ABS sensors, fuel pumps, stamped parts, clamps and ride-height sensor enquiries.
We work with customers through concrete requirements: OE references, specifications, quantities, packaging needs and target markets. The details are the starting point for cooperation.
