China Shipbuilding Group Changjiang Technology Co., Ltd. is a wholly-owned subsidiary of China State Shipbuilding Corporation Limited. It was formed through the integration and reorganization of CSSC Chongqing Changping Machinery Co., Ltd. and Chongqing Changjiang Coating Equipment Co., Ltd. Its predecessor can be traced back to Chongqing Changjiang Coating Machinery Factory established in 1981. The company is headquartered in Wanzhou District, Chongqing, covering an area of approximately 350 mu. It currently has more than 700 employees, including more than 150 professional technical personnel (among them 4 researchers and more than 30 senior engineers), with a registered capital of 222 million yuan. The company is committed to developing into a world-class R&D and manufacturing center for fluid handling equipment and an important domestic supplier of communication and navigation equipment systems. Its products are widely used in shipbuilding, bridge engineering, petrochemicals, wind power generation, rail transit, new energy, equipment manufacturing, and national key projects, serving nearly 4,000 customers and nearly 70 dealers nationwide.
Five Core Product Lines:
I. Coating Equipment and Coating Engineering. Covering airless sprayers, fireproof coating sprayers, intelligent spraying production lines, etc. It is an important integrated general contractor supplier in the coating industry, capable of providing integrated solutions from single-machine equipment to complete line design, manufacturing, and installation. The company is the drafting unit of the industry standard "Airless Sprayer" and participates in the formulation of the national standard "Safety Code for Coating Operations."
II. Intelligent Glue Application Equipment. Applied in fields such as complete vehicles, new energy batteries, solar energy, rail transit, equipment manufacturing, and communications, helping the manufacturing industry achieve precision glue application automation.
III. Lubrication Equipment. Possessing series products including dry oil centralized lubrication systems, thin oil cooling lubrication systems, and thin oil stations, providing reliable lubrication guarantees for heavy equipment.
IV. Sandblasting Equipment. Including shot blasting machines, dust collectors, and other surface treatment equipment to meet the needs of pre-treatment for heavy anti-corrosion coating.
V. Communication and Navigation Equipment. Professionally R&D and manufacturing electro-controlled gyrocompasses, fiber optic compasses, fiber optic gyroscopes, flexible gyroscopes, north finders, and other inertial devices. It is an important domestic integrated supplier of communication and navigation systems.
In terms of technological innovation, the company has cooperated with Chongqing University to R&D the hollow wrist-type coating robot TZR-2, which is internally inflated and explosion-proof, filling the gap of domestic robots in the field of intelligent coating. It has cooperated with Harbin Institute of Technology to develop complete sets of automatic spraying equipment for ultra-large ship hull sections, and took the lead internationally in launching vehicle-mounted mobile coating robot spraying equipment, reducing the coating coefficient from 2.2 to the internationally advanced level of 1.8. The independently developed CJ400 PFP fireproof coating sprayer has passed the official certification of International Paint under the global coating giant AkzoNobel, and has served major domestic and international projects such as Hong Kong LNG, Canada LNG, Pluto 2, Scarborough, and Woodfibre, cumulatively completing more than 1,000 tons of fireproof coating spraying operations.
In terms of intelligent manufacturing, the company has cumulatively obtained 192 patent authorizations and holds 57 registered trademarks including "Changjiang Technology" and "China Heavy Industry Changjiang." It has built 6 intelligent flexible production lines, invested 17 million yuan in recent years to promote digital transformation, overall production efficiency increased by 1.8 times, product defect rate decreased by more than 95%, and operating costs decreased by nearly 20%. It has been recognized as a municipal-level digital workshop.
The company's qualification system is complete. It is a national high-tech enterprise, a national-level specialized, high-end and innovation-driven "little giant" enterprise, a Chongqing Municipal Technology Innovation Demonstration Enterprise, and a Chongqing Municipal Specialized, High-end and Innovation-driven Enterprise. It has two Chongqing municipal-level technology centers, has passed ISO 9001 Quality Management System, ISO 14001 Environmental Management System, and ISO 45001 Occupational Health and Safety Management System certifications, and possesses Grade II professional contracting qualification for building mechanical and electrical installation engineering. The "Changjiang" trademark is a "China Well-known Trademark" and has a relatively high market share in fields such as shipbuilding and bridge engineering.
The company possesses full-chain service capabilities from R&D and design, core equipment manufacturing to complete line integration and general contracting. In the field of coating engineering, it can provide integrated services for complete production lines including spraying, sandblasting, dust removal, and intelligent glue application. In the field of communication and navigation, it provides devices such as gyrocompasses, fiber optic gyroscopes, and north finders, as well as communication and navigation system integration solutions. Relying on the global resources of China State Shipbuilding Corporation and the "Belt and Road" market network, the company has the capability and experience to serve the global industrial engineering market, using "China Intelligent Manufacturing" to help the industry achieve high-quality development and provide global customers with more efficient and reliable equipment and overall solutions.
