The Round Flange Forming Machine is a fully automatic CNC equipment specially designed for producing round flanges in ventilation and HVAC systems. Driven by a servo motor, it realizes high-precision automatic feeding, forming and cutting for round flanges (φ250～φ3600mm), with an indexing accuracy of ±0.1mm. Equipped with a user-friendly TFT touch interface and high-hardness quick-change forming molds, the machine adopts a robust multi-roller structure and double-beam frame design to ensure long-term stability and consistent forming precision. It is a core equipment for efficient production of round air duct flanges, which greatly reduces manual operation and material waste, and is widely used in HVAC, ventilation and air purification industries.

TDF法兰成型机主要用于在板材边缘制作翻边以便进一步连接，也是现代风管成型生产线的基本设备之一。TDF法兰成型机使用的所有轴承都是滚珠轴承而不是传统的滚针轴承，因此TDF法兰成型机更耐用。TDF法兰成型机成型的法兰形状美观实用，是风管成型生产线的完美组成部分。

TDF flange forming machine, mainly used for making flange at edge of plate for further joint, is also among basic equipment for modern duct forming line.All bearings of TDF flange forming machine used are ball bearings rather than traditional needle bearings, so the TDF flange forming machine is more durable.The flange shape made by the TDF flange forming machine is nice and practical, which makes it a perfect part of duct forming line.
