Company Profile
Wenzhou Jianqing Industrial Company Nestled within the revered South Zhejiang Marine Economic Development Zone at the Oujiang Estuary, Wenzhou Jianqing Industrial Company stands as a beacon of modern industry. This illustrious company proudly contributes to national efforts to cultivate cutting-edge industrial clusters, showcasing an unwavering commitment to modern innovation and advanced industrial prowess.
Founded in the industrious year of 1977, Wenzhou Jianqing Industrial Company has an illustrious history that unfolds across three transformative phases: Phase 1 (1976-1990), Phase 2 (1992-2002), and Phase 3 (2002-2023). Under the visionary leadership of founder Chen Jianqing, alongside a dedicated team, this ambitious journey began in 1976. The company initially navigated challenging conditions to meticulously craft valves, delivering their inaugural valve batch that secured vital capital. By 1977, the collaboration with Longwan School Office led to the formation of Wenzhou Tianlong Petrochemical Machinery Factory, marking a pivotal milestone. Initially focused on crafting seal rings amidst a backdrop of production challenges, the founders' determination surmounted each obstacle, systematically resolving any production and sales challenges, thus laying a robust foundation for future growth.
Fueled by an unwavering commitment to progress, by 1979 the company strategically broadened its product range. Transitioning from a sole focus on sealing parts, they diversified into manufacturing air valves, packing elements, pistons, piston rods, and bearing bushings. By 1984, a transformative shift to private ownership heralded the creation of Wenzhou Air Compressor Valve Factory, establishing a pioneering presence as Wenzhou's foremost comprehensive manufacturer of compressor parts.
As the 1990s emerged, their superior quality offerings gained market recognition. This newfound reputation granted them entry into the prestigious circle of designated production enterprises for the Petrochemical Industry Bureau (formerly the Ministry of Chemical Industry). They became an integral part of China National Gas Corporation's network for refining and chemical spare parts and gained entry into the resource market for China's Petrochemical spare parts.
In 1992, a new era of transformation commenced with strategic shareholding reform, marking the official renaming to Wenzhou Jianqing Industrial Company. This pivotal transition heralded the dawn of a new chapter characterized by growth, innovation, and strategic realignment.
Post-2000, Wenzhou Jianqing Industrial Company embarked on an unparalleled journey of self-reinvention. Building upon years of meticulous product refinement, they progressed from merely emulating imports to innovating unique designs and spearheading independent research and development. This step-by-step approach has firmly cemented their esteemed status within the dynamic industrial landscape of today.
