Volume Control Damper Frame (VCD Frame) Roll Forming Machine - High-Quality and Efficient Solution

1. Fast speed: forming speed of 0-6m/min,can produce 300–400 frame 8 hours 2. High precision: hole distance error ± mm, length error ± 0.5 mm 3. High efficiency: continuous order mode for continuous production. 4. Good forming effect: specially designed rollers to ensure less abrasion to zinc layer after galvanized sheet is formed. 5. Small bending R: specially designed bending tool as well as pre-punching in dentation at the small edge to ensure that the bending angle is small.
