TDC flange is one of the most widely used duct flanges in the world. It has the characteristics of time-saving, material saving, high work efficiency, good sealing, sturdy and durable, and strong connection. It is especially suitable for ducts with a large cross-section of ventilation ducts. The TDC flange forming machine is mainly composed of a feeding frame, a cold rolling forming main body, and a cutting part. It is equipped with a high-speed steel circular saw blade non-stop cutting system. It can be cut to length. The burr is small and can be fully automated. Its working speed is 6 meters/minute. According to its working performance and flange strength and sealing grade, it can be divided into five types: T-20, T-25, T-30, T-35, T-40, and the corresponding connection angle model is T-20DC, T- 25DC, T-30DC, T-30DC, and T-40DC.
