In response to the global shift toward greener and more intelligent solutions in the shipbuilding industry, the demand for efficient, reliable equipment for key operations like ship launching and shifting continues to rise. Qingdao Sunkai Marine Supplies Co., Ltd., situated in Qingdao’s bustling shipbuilding industrial hub, has been at the forefront of this transformation. Specializing in the R&D and production of high-quality marine airbags, the company has built a solid reputation by adhering to national standards, ensuring top-tier quality and cost-effective solutions for maritime enterprises worldwide.
At Qingdao Sunkai, the safety of maritime operations is paramount. The company understands that the quality of marine airbags is directly tied to the protection of personnel and property during key activities such as ship launching, maintenance, and rescue operations. This commitment to safety is reflected in Sunkai’s standardized production process, which begins with the careful selection of raw materials. High-strength synthetic fiber cord fabric and aging-resistant rubber composites are used to ensure that the airbags meet the stringent requirements of GB/T33487-2017 and ISO 14409 international standards.
Every stage of the production process is rigorously monitored—vulcanization temperatures are controlled precisely between 150°C and 160°C, and the cord fabric overlap width meets the technical specification of at least 50mm. The company maintains detailed traceability for each step, from rubber mixing to product formation. Before leaving the factory, each airbag undergoes a series of quality tests, including a 24-hour airtightness test (with a pressure drop not exceeding 5%) and a burst pressure test to ensure safety standards are met.
With a modern production base spanning over 8,000 square meters, Qingdao Sunkai is equipped with 8 advanced production lines, allowing the company to meet large-volume orders with ease. Its factory-direct sales model eliminates the price markups added by intermediaries, passing on the cost savings directly to customers. This approach not only makes Qingdao Sunkai’s marine airbags more affordable but also enhances their competitiveness in the global market.
The company offers a wide range of airbag products to cater to different operational needs. With diameters ranging from 0.8m to 2.0m and effective lengths from 6m to 10m, Sunkai’s airbags can accommodate small ships weighing thousands of tons, as well as massive merchant vessels and offshore engineering platforms. Customization options allow clients to select the right airbag configuration for their specific needs.
Qingdao Sunkai’s commitment to quality and cost-efficiency has earned it a strong customer base, both domestically and internationally. The company’s products are widely used in major shipbuilding regions such as the Bohai Rim and the Yangtze River Delta, and it has formed long-term partnerships with prominent enterprises like Shandong Shipping and Zhejiang Shipbuilding.
On the global stage, Qingdao Sunkai’s marine airbags have been exported to countries along the “Belt and Road,” including Southeast Asia and the Middle East. Notably, they played a crucial role in helping a Vietnamese shipbuilding company launch a 5,000-ton cargo vessel. The company’s products are also used in a variety of operations, including ship launching, maintenance, dismantling, and maritime rescue, earning high praise from international clients.
At Qingdao Sunkai, the mission is clear: “Making every maritime operation safe and efficient.” The company remains committed to the evolving needs of the shipbuilding industry, focusing on material innovation and process improvement. As part of its ongoing development, Qingdao Sunkai is working to enhance the load-bearing capacity and service life of its airbags.
