Since its establishment in 2006, Qingdao KEEJOO Group has always focused on the research, development and manufacturing of high‑end shot‑blasting machines. It is recognized as a national high‑tech enterprise within the industry. Integrating technological R&D, precision manufacturing and comprehensive services, the company is committed to delivering cost‑effective, high‑quality shot‑blasting solutions for global customers.

Founded in 2006, Qingdao KEEJOO Group regards technological innovation as its primary driving force for development. By introducing advanced technologies from world‑renowned brands such as Wheelabrator and DISA, the enterprise has gradually mastered the core manufacturing processes for shot‑blasting wheels.

Thanks to excellent product quality, the shot‑blasting machines manufactured by Qingdao KEEJOO Group have obtained ISO 9001 international quality management system certification, EU CE certification and German TUV certification. Our products are exported to 89 countries and regions across the globe, including major industrial powers such as Germany, the United States, Japan and South Korea. They are widely applied in the nuclear‑energy field (e.g. the independently‑developed HS3750 hook‑type shot‑blasting machine for nuclear‑energy valves), automobile manufacturing (serving well‑known manufacturers including FAW‑Volkswagen and Suzuki), shipbuilding (such as Jiangnan Shipbuilding) and steel‑structure construction (with a strategic‑cooperation partnership established with China Hangxiao Group). By 2023, the company had cumulatively designed and manufactured more than 240 large hook‑type pass‑through shot‑blasting machines, which have won wide recognition on both domestic and international markets.

In recent years, Qingdao KEEJOO Group has continuously invested in the research, development and innovation of shot‑blasting technology. Remarkable breakthroughs have been achieved in wear‑resistant spare‑part materials, shot‑recycling circulation systems, dust‑removal efficiency and environmental‑protection performance. As a result, our products feature a longer service life, lower maintenance costs and better operational economy. Guided by the development philosophy of “Building a three‑dimensional win‑win system and manufacturing high‑quality shot‑blasting machines”, the company is steadily advancing toward its goal of becoming a leading enterprise in the global shot‑blasting‑machine industry. Today, Qingdao KEEJOO Group has grown into an important base in China for the manufacturing, casting‑production and export of shot‑blasting machinery, continuously creating value for customers worldwide.
