We are the Overseas General Agent of Wanshun Group, Provider of international construction, transportation intelligence, dimming, energy saving and environmental protection solutions. Committed to the global energy conservation and environmental protection cause. Specializing in the promotion, design, sales, and construction of architectural window film and transportation door and window film, providing customers with professional energy saving solutions. Our business is based in Shanghai, serving the whole country and covering the world. The thermal insulation film factory was established in 1998 and is located in Shantou Free Trade Zone in Guangdong Province. It integrates research and development and production, and is a national high-tech enterprise. The core products "Photochromic Window Film" & "PDLC Smart Film" & "Paint Protecion Film" have independently developed core patented technologies, and Beijing Zhongzhi Tonghui Co., Ltd., a state-level high-tech enterprise with a subsidiary in which it holds shares, is a leading enterprise in the domestic dimming glass product industry. Our production base has passed ISO9001 international quality management system certification and ISO14001 international environmental management system certification.

Our energy-saving film is a multi-layer functionalized polyester composite film material, which is processed by dyeing, vacuum evaporation, magnetron sputtering, lamination and other processes on the polyester film. The energy-saving film attached to the glass surface can improve its performance and strength, so that it has the functions of heat preservation, heat insulation, energy saving, explosion protection, UV protection, infrared protection, aesthetics, privacy, etc. It is mainly used in automotive glass, building windows and doors, and partitions. Glass, ceiling glass, etc. Through years of accumulation, the factory has mastered core technologies such as vacuum evaporation, magnetron sputtering, and coating compounding, and its performance indicators have reached advanced levels. It has a technical team with rich practical ability and has introduced a team of overseas experts to establish a complete, advanced and reliable production operation specification system. With the increase of new automobile sales and ownership, the market demand for energy-saving films for automotive glass is increasing day by day. In terms of domestic architectural glass applications, more than 95% of existing buildings are high-energy-consuming buildings, and the energy consumption per unit area is 2-3 times that of developed countries. The demand for energy-saving films for architectural glass will increase as people's awareness of environmental protection increases. The introduction of energy-saving film products has followed the trend of environmental protection and energy-saving green development.
