Zhejiang Dongxin Power Co., Ltd. was established in 2002 with a registered capital of 15.8 million yuan. The company is located at No. 288 Nanbin Third Road, Nanbin Street, Rui'an City, Zhejiang Province, covering an area of 30 acres and a building area of 26,000 square meters.Dongxin is committed to building an industry-leading supplier of key components for marine power systems, having been honored with titles such as National High-Tech Enterprise,National Specialized, Fined, Peculiar, and Innovative "Little Giant" Enterprise.

Dongxin Power mainly produces inline and V-shaped cylinder bodies and cylinder heads with diameters ranging from 4 to 20 cylinders and 100 to 330mm. They are key components of energy engines such as diesel, methanol, and natural gas, serving national strategic emerging industries such as power stations, big data computing centers, and marine power. The company has established long-term strategic partnerships with a number of Fortune 500 companies, benchmark state-owned enterprises such as SAIC Motor Corporation Power New Technology (Shanghai Diesel Engine Co., Ltd.), Shanghai Lingzhong (Mitsubishi Heavy Industries, Ltd.), CSIC Shaanxi Diesel, CSIC 711 Research Institute, Ningbo Zhongce, as well as other top diesel engine manufacturers in the industry.

It mainly produces key components for diesel, methanol, natural gas and other energy engines, including inline and V-type cylinder block and cylinder head series with 4 to 20 cylinders and a bore diameter of 100 to 330 mm, and other related series. These products serve strategic emerging industries such as power stations, big data computing centers, and marine power. The company has established long-term strategic partnerships with leading world-class and state-owned enterprises, including Shanghai New Power Automotive Technology Co., Ltd.(SAIC), Shanghai MHI Engine Co., Ltd.(SME，a joint venture with Japan's Mitsubishi Heavy Industries),   CSSC Shaanxi Diesel(SXD), CSSC SMDERI and Ningbo C.S.I.POWER, together with other premier diesel engine manufacturers.

Equipment precision, craftsmanship casting quality. Dongxin Power has invested nearly 100 million yuan to lay out high-end processing and testing equipment: the core manufacturing matrix is composed of processing centers such as Nicolas from Spain, Niigata from Japan, and Doosan from South Korea. The quality control of each process is firmly ensured by the German Hexagon coordinate system and Spike spectrometer, and the MES system realizes the closed-loop data of the entire process. Thanks to this, the maximum processing length of the cylinder series products can reach 6000mm, significantly improving product precision and consistency, providing strong support for the core supporting products of our partners.

The cylinder block is the most fundamental load-bearing component and pressure bearing chamber of diesel engines. Its strength and accuracy are important benchmarks for measuring the upper limit of engine power and the bottom line of its lifespan, and are essential basic components in the internal combustion engine industry chain.

Zhejiang Dongxin Power, as a key enterprise in the national cylinder block subdivision field, leads the development of the "Zhejiang Manufacturing" group standard, continuously researches and develops high-strength and high-precision cylinder block technology, achieves a phased leap from "being able to do" to "being refined", and contributes Dongxin's strength to promoting the high-quality development of the domestic internal combustion engine industry.
