As a leader in the industry, Shanghai Songjiang Vibration Isolator Group Co., Ltd. has disclosed the core information of the spring vibration isolator contract for the [Ningbo Jinmao Square Project] on its official website. For a long time, with its exquisite technology and craftsmanship, the group has customized high – quality vibration isolators for urban complexes and has earned an excellent reputation.

I. Spring Vibration Isolators: The Crystalization of Technology and Quality
(I) Materials and Manufacturing
The spring vibration isolators of Shanghai Songjiang Group are made of high – quality steel with a special formula. This type of steel features high strength and toughness. Its yield strength and tensile strength are much higher than the industry average, enabling it to maintain stable mechanical properties under long – term dynamic loads. Through advanced smelting processes, the steel has extremely low impurity content, ensuring material uniformity and stability. During the manufacturing process, the steel is first precisely forged to make its internal structure more compact and enhance its overall strength. Subsequently, it undergoes numerical control machining to ensure that the dimensional accuracy of the spring is controlled within a very small error range, laying the foundation for the subsequent heat – treatment process. After multiple strict heat – treatment procedures, the spring achieves the ideal hardness and elasticity, and can withstand frequent impacts and vibrations without fatigue failure.
(II) Performance Advantages
The unique spring design is the key to its excellent performance. By optimizing the geometric parameters and winding method of the spring, it has excellent elastic deformation ability. When facing the vibrations generated by the operation of equipment such as water pumps and air – conditioning units, it can quickly convert the vibration energy into the elastic potential energy of the spring, effectively absorbing and buffering the vibrations. Through professional testing, this spring vibration isolator can reduce the vibration transmission rate to less than 5%, significantly outperforming similar products in the market. It can efficiently handle both low – frequency structural vibrations and high – frequency equipment operation vibrations. In practical applications, it can create a quiet environment inside the building, reducing noise by 20 – 30 decibels. At the same time, it greatly reduces the damage to the equipment and building structure caused by vibrations, extending the service life of the equipment by more than 30% and effectively ensuring the safety of the building structure.
II. Ningbo Jinmao Square Project: A New Benchmark for Urban Development
As a landmark building in Ningbo Life Science City, the approximately 190,000 – square – meter large – scale commercial complex of Jinmao Square integrates diverse business forms such as Jinmao Hotel, Jinmao Hui Commercial, and Class – A office buildings, and is an ideal carrier of the future lifestyle.
The 4 – square – kilometer Ningbo Life Science City has gradually fulfilled its blueprint after five years of development. As an “urban operator”, China Jinmao is committed to integrating industries, introducing new business forms, and improving public supporting facilities to enhance the competitiveness of enterprises and the quality of life of residents in the area.
As an enterprise under Sinochem Holdings, one of the world’s top 500 companies, China Jinmao has maintained a green status in all “three red lines” indicators since 2020, indicating its financial stability. In 2021, its contracted sales volume reached 235.6 billion yuan. In 2022, its unrestricted cash balance increased from 31.1 billion yuan to 32.9 billion yuan, and the financing cost was only 3.76%, providing strong support for the project.
As urban construction enters the 3.0 era, the construction of the Western Hub has brought new opportunities to the Science City. The newly topped – out Jinmao Hui complex of over 190,000 square meters integrates three core business forms, creating a TOD one – stop landmark and a fashionable living scene. Jinmao Huamanli combines prosperity, ecology, and quality, creating an ideal living model in the Ningnan TOD area.
