What is the maximum diameter of PC (polycarbonate) glass for car side windows in Asia? The answer is 1.2 meters. The authoritative answer to this question comes from Yuyao. In the exhibition hall of Shentong Technology Group Co., Ltd., one side of PC glass with smooth curved surface and smart lines is quietly displayed, waiting for inspection from customers around the world.
In recent years, with the further increase in the demand for environmental protection and energy saving, automobile lightweight has become the trend of the development of the world’s automobile industry. The use of lightweight materials is the main measure for the current lightweight of automobiles. As an emerging window material, PC windows have unparalleled advantages in high safety, design freedom and lightweight compared to traditional glass windows.
As an enterprise that has been deeply involved in the auto parts industry for more than 40 years, Shentong Technology is mainly committed to the R&D and manufacturing of automotive power systems, trim systems, molds and other fields. With leading R&D technology, manufacturing technology, quality management and global supply capabilities, and Many automakers at home and abroad have established good technical cooperation relationships, and have become global suppliers of GM, Volkswagen, Geely, GAC, Great Wall, BMW and other automakers.
In 2016, Shentong Technology was keenly aware of the lightweight trend of passenger cars, and cooperated with SAIC-GM to develop large-size PC glass, and successfully launched side window glass with a diameter of 1.2 meters in 2018, becoming Asia’s largest production of side window PC glass in Asia supplier, and as the exclusive global supplier for Buick GL8 models. Only one research and development has brought the company an annual output value of 60 million yuan, and has maintained steady growth for five consecutive years.
Since the weight has shrunk by nearly 50%, can PC glass resist high temperature, sand, and ice-melting tools? In response to the questions raised by the reporter, Rao Lianchao, Director of Shentong Technology Research and Development Center, said that in fact, the PC window itself has the characteristics of more difficult molding process and higher precision requirements. Aiming at the problem of product quality defects caused by internal stress phenomenon that often occurs in the injection molding process of PC materials, Shentong Technology relies on the world’s leading R&D and manufacturing level, and adopts AM (Additive Manufacturing) technology to make PC glass products, regardless of strength or size, have reached a very stable state. At the same time, the double-sided flow coating process is adopted to achieve surface hardening treatment, which helps the product to have superior scratch resistance, impact resistance and heat resistance. Coupled with the flexible 3D curved surface technology, all the effects that can be realized on the existing quartz glass can be realized, so the core competitiveness of the product has also been further strengthened.
Shentong Technology has many other high-tech and irreplaceable products like PC glass for large-size car side windows. “For example, the active oil-gas separator that we have just achieved small-scale production recently reduces the oil-gas separation effect to 0.5 grams of engine oil per hour, successfully solving the ‘stuck neck’ problem, and is currently the only domestic company that can independently develop and produce this type of product Enterprise.” Rao Lianchao said. As a technology-based company adhering to the concept of innovation support, Shentong Technology’s annual R&D investment also accounts for about 6% of its output value. “Reinforcing while maintaining stability, improving while maintaining stability, and improving quality while maintaining stability”, Shentong Technology is in the ascendant in terms of firm positioning as a core component supplier in the automotive field.
