    2025: Technological breakthroughs to strengthen core competitiveness.

    In March, the company filed a patent application for a “new-type handle-controlled pressure-regulating valve” and subsequently obtained authorization. This patent effectively ensures stable pressure in pneumatic systems, further enhancing the company’s technological edge in the field of pneumatic control. In the same year, the company emphasized in its public communications that it maintains full independent control over the entire product development and production process—from R&D to manufacturing—and has established deep, long-term partnerships with major domestic equipment manufacturers. Its products are now exported to numerous countries worldwide. Meanwhile, as a high-tech enterprise, the company actively participates in industry-related events, continuously expanding its influence within the sector.

    2024: Scaling up and expanding our business footprint with Shuidi Credit.

    On June 19, the company completed an important business and industrial change, significantly increasing its registered capital from RMB 1 million to RMB 5 million. At the same time, the company’s articles of association were filed and approved. This capital increase provides stronger financial support for the company’s technological research and development, capacity expansion, and market development.

    2007–2023: Steady growth, continuous system improvement, and enhanced reputation.

    During this phase, the company continued to deepen its focus on its core business and gradually expanded its product portfolio to include over 1,000 items across seven major series—such as specialized pneumatic components for petroleum machinery and air-source treatment devices—catering to the specialized equipment needs of various industries including oilfields, mines, and railways. During this period, the company not only established a comprehensive internal quality-control system but also obtained ISO9001 certification for its quality management system. Thanks to its reliable products and services, the company has built a strong industry reputation. At the same time, it has steadily developed domestic and international sales channels, laying a solid foundation for future market expansion. In addition, during this period, the company began placing greater emphasis on intellectual property strategy, gradually accumulating achievements in patents, trademarks, and other forms of intellectual property.

    2007: The company got off the ground and laid the foundation for its business.

    On November 8, the company was officially established under the name “Weihai Zhonghao Pneumatic Complete Equipment Co., Ltd.” Its predecessor was the state-owned Weihai Pneumatic Components Factory. From its inception, the company focused on the R&D and production of pneumatic components and hydraulic components for oilfield machinery and drilling equipment, laying a solid foundation for its subsequent deepening engagement in the pneumatic and hydraulic fields.
