Thirty years of development of metal air duct manufacturing technology Before the 1990s, the application scope of ventilation and air conditioning systems was limited. The processing volume of metal air ducts was small and the quality requirements were not high. Most of them were completed by manual hammering and supplemented by simple general machinery. After the reform and opening up, with the rapid development of my country's economic construction and the continuous improvement of people's requirements for production and living environment, ventilation and air conditioning facilities are widely used in various industrial and civil buildings, among which the processing and manufacturing volume of metal ventilation ducts has increased linearly. , continuing to use manual hammering work is far from meeting the requirements of construction progress and construction quality. With the exchange of construction technologies for domestic and foreign building installation projects, metal air duct processing technology and equipment have experienced a process from scratch, from simple transplantation to development, from single technology application to integrated technology application, which has improved the construction quality of ventilation and air conditioning projects in our country. and equipment level, and is developing rapidly in the direction of intelligence, energy conservation, and high efficiency.
