According to information presented at the Shanghai Medical Equipment Exhibition, Shanghai Xinliang Stainless Steel Tube Co., Ltd. (hereinafter referred to as Shanghai Xinliang), which has been specializing in the production of precision stainless steel tubes for 26 years, continues to occupy a leading position in the medium and high-precision tube products segment due to its technical competence and strong reputation in the market.As a high-tech enterprise and a specialized, professional and innovative enterprise, the company adheres to the concept of:“Precise production, strict management, superior quality in every pipe; high quality and high efficiency, complete satisfaction for every customer.” The company provides customized solutions for high-tech industries such as medical equipment, automobile industry and semiconductor industry, demonstrating the high level of Chinese industrial manufacturing.
Founded in 1996 in Zhujiajiao District, Qingpu District, Shanghai, today Shanghai Xinliang has grown into one of the leading enterprises in the industry, with a modern production complex covering an area of 12,000 m² and more than 100 units of specialized production equipment. The company has formed a team of experienced professionals and implemented a modern management system. At various times, the company has successfully passed ISO 9001 certification, creating a solid foundation for ensuring stable product quality.
Technological innovation is a key factor in a company's competitiveness. In 1997, Shanghai Xinliang's stainless steel capillary tube for gel pen writing units (outer diameter 0.3 mm, wall thickness 0.08 mm) was developed by Shanghai Xinliang to overcome its dependence on imported products and made the company one of the main suppliers to Chinese writing instrument manufacturers.
After entering the medical device market in 2012, the company collaborated with several enterprises, including Shanghai MicroPort, to develop special tubes for surgical stapling machines. The products are made of medical grade 304 stainless steel, and the internal surface roughness is Ra ≤ 0.4 microns. These products are used in more than 500,000 units of minimally invasive surgical equipment. Flexible endoscope tubing with a minimum bend radius of 5 mm has been successfully used in gastroenterological research, and medical gas piping has become an important element of oxygen supply systems in intensive care units.
In the New Energy Vehicle sector, the company has developed high-precision stainless steel battery cores that are considered the industry's benchmark component. The products are manufactured from high-strength 304 grade stainless steel and fully meet the structural support and heat dissipation requirements of batteries. The outer diameter of the tubes is 2.0-3.0 mm, and the deviation in wall thickness uniformity does not exceed ±0.02 mm. The tubes are able to withstand temperature cycles from -40°C to +85°C during charging and discharging batteries, and are highly resistant to vibration and corrosion, ensuring long-term stability of the battery pack design. In 2016, this product was recognized as "High Quality Product" by the Shanghai Association tube industry and has been successfully used in automobile manufacturers such as BYD and SAIC Motor. In the semiconductor industry, ultra-clean semiconductor equipment tubes and high-pressure sensor tubes are used in chemical pressure control systems, automotive engine diagnostics and other high-precision applications, providing high precision data transmission through strict sizing.
Currently, the company's product range includes several series of products, including ultra-thin and ultra-long capillary tubes with outer diameters ranging from 0.5 mm to 16.0 mm, meeting the needs of various high-tech industries. High quality products are ensured by modern production and inspection technologies. The company is equipped with five-axis laser cutting machines, laser welding equipment and bright annealing furnaces, allowing complete control of the production process. Quality control is carried out using coordinate measuring systems, surface hardness and roughness measuring equipment, and other advanced inspection methods. Due to the high quality of products, Shanghai Xinliang products have been exported to more than 10 countries and regions, including the United States and the European Union. Sanitary grade pipes for coffee machines, manufactured by order of the German company WK, have successfully passed European certification, and for more than twenty years of cooperation, not a single quality complaint has been recorded.
Main stages of company development:
1.2000 - transfer of production to the village of Maogang, Songjiang District and transition to large-scale development;
2.2008 - obtaining ISO 9001 certificate;
3.2011 - awarded the title of “Advanced Enterprise of Songjiang Region”;
4.2017 - moving to a new production site in the village of Chedun;
5.2019 - receipt of IATF 16949 certificate;
6.2020 - obtaining the status of an enterprise in the “Specialized, Professional and Innovative” category and a certificate of a High-Tech Enterprise.
Looking forward, Shanghai Xinliang will continue to develop precision stainless steel tube manufacturing technology, focusing on developing advanced products including lightweight composite tube structures, as well as expanding the application of products in aerospace and high-tech mechanical engineering. The company strives to become one of the world's leading experts in the processing and production of precision tube products, contributing to the high-quality development of China's modern industrial manufacturing.
