In recent years, the global shipbuilding market demand is active, the new orders of domestic and foreign shipping enterprises have increased greatly, the price of new ships continues to rise, and the demand for shipbuilding in the medium and long term continues to improve. According to the data on the website of the Ministry of Industry and Information Technology, in the first half of 2024, China's shipbuilding completion was 25.02 million DWT, up 18.4% year on year; 8.4% of new orders was 54.22 million DWT, up 43.9% year on year; in the first half of this year, China's shipbuilding indexes accounted for 55.0%, 74.7% and 58.9% of the global total, respectively, consolidating its position as a major shipbuilding country. Tongyu Heavy Industry closely grasps the market demand brought by the development of the shipbuilding industry, and actively improves the layout of Marine supporting products by relying on the advantages of technology and industrial chain, so as to help the rapid development of China's shipbuilding industry.
With the profound accumulation in the field of wind power spindle, pipe die and other forgings products, as early as 2007, the company successfully transformed the technology, equipment and other advantages to the production of Marine forgings products. After smelting, forging, heat treatment, machining and other processes, one after another Marine key components were successfully rolled off the production line from Tongyu Heavy Industry and delivered to users. From the original Marine shaft forgings products, to the current covering large Marine shaft, rudder forgings-intermediate shaft, propeller shaft, rudder rod, rudder pin, curve, etc., the company's new product development pace has never stopped. Marine products from zero to one, and then from one to more, it has been more than ten years. In this process, the company encountered super long ship shaft center hole processing prone to deviation, finishing ship shaft outer circle size precision requires high production technical problems, have been overcome, now has a stable research and development manufacturing capacity, and has successfully provide customers with more than 20 meters long stern shaft and single weight nearly one hundred tons of Rudder stock and other products.

The company has established a mature Marine forgings marketing, technology, production team, production and processing equipment and other hardware strength is constantly enhanced. At present, the company has 120MN, 50MN, 31.5MN, 12.5MN free forging oil press and supporting operators, forging driving and heating furnace, forming systematic forging production capacity; nearly 400 sets heavy machining equipment such as CNC horizontal lathe, CNC double pillar truck, deep hole drilling and boring machine, which can process vehicle, boring, milling, grinding and drilling, with advanced machining ability. In order to improve the processing capacity of curved arm products, the company also added a special vertical car, which can realize the rough processing and semi-finishing processing process at the same time, at the same time, the tools, tooling and process routes to improve production efficiency.

With advanced production equipment, excellent scientific research and production talent team, the company has obtained nine classification certification CCS, BV, LR, DNV, ABS, NK, KR, RINA and RS. At present, the company can undertake the production of all ship shaft products within 30 meters, and the rough processing and finishing of all winding arm products below G98.
The company actively expands the domestic and overseas market territory. Domestically, the company has established a good long-term cooperative relationship with Guangzhou Shipbuilding International Co., Ltd., Hudong Zhonghua Shipbuilding (Group) Co., Ltd. and achieved batch supply, highlighting the company's strong manufacturing strength and market competitiveness in the field of ship supporting products. In addition, the company has also reached a strategic cooperative relationship with Dalian Huarui Marine Crankshaft Co., Ltd. and Yuchai Marine Power Co., Ltd. on the manufacturing field of large Marine crankshaft forgings and Marine low-speed diesel engine casting and forging products respectively, to achieve mutual benefit and win-win results and common development. At the same time, the company has also extended its Marine products business to a broader overseas market, and has cooperated with the world famous companies Becker Marine, DAMEN, etc. On the basis of providing conventional steering rod, rudder pin and other products, but also committed to meeting the diversified and personalized needs of customers, customized production of special shape forgings and other cutting-edge products.
Over the years, the company closely around the national industrial policy, follow the shipbuilding industry high-end, intelligent, green development trend, continue to optimize Marine product manufacturing capacity and product structure, strengthen the Marine high-end parts mass orders, to provide customers with high quality products and services, for the high quality development of our shipbuilding industry.
