Changzhilin Technology

Dalian Changzhilin Technology Co., Ltd. (hereinafter referred to as "the Company") was established in 2005. It is a private high-tech enterprise focusing on the aviation industry, specializing in the research and development, manufacturing, and sales of aviation components. To meet the needs of localized market deployment, the Company provides "door-to-door" services to customers, forming a networked layout of aviation business operations. The Company's main products include aviation clamps, heat shields, and pipeline connectors. Leveraging its expertise in pipeline connection technology and titanium alloy hot forming processes, it undertakes processing of aircraft and aero-engine pipelines as well as precision components (including but not limited to casings and blades). Its products and services are widely applied and supplied to all aircraft and aero-engines under development or in mass production. The Company has outstanding business advantages: its core product, "aviation clamps," maintains a leading domestic market share; its key product, "heat shield blanket/pad" technology, has achieved import substitution, breaking foreign monopolies and contributing to the successful maiden flight of the domestic large aircraft C919 on schedule, leading the domestic market share; its pioneering product, "pipeline connectors," specifically the "flareless pipeline connection technology," was independently developed by the Company, breaking long-term foreign technical blockades and filling a domestic market gap. It has gained recognition in the pre-research, trial production, and test flight stages with customers, occupying a market-leading position within the industry. With significant advantages in core technical teams, independent intellectual property, and comprehensive service capabilities, the Company has become a qualified and strategic supplier of aviation components, recognized for its high level of specialization, rich technical accumulation, and strong customer acceptance.
