Multi-Duct Former (MDF)

The FIRMAC MDF machine Line is designed to operate in three (3) separate stages, giving the same quality integral flange ductwork as the Firmac Pro-Duct DRS machine, with increased handling but less capital expenditure. The MDF offers either CGF1 or CGF2 integral flanges using a simple three (3) machine process allowing efficient ductwork manufacture for medium to high volume workshops. The three stages are described below

Machine 1

Creates the ductwork blank direct from coil with, levelling, stiffening and notching for the corner folds, and Pittsburgh seam detail. The added feature of the inline Pittsburgh creates the male and female seam as it cuts through the material. The result of this stage is a flat blank in preparation for rolling the integral flange
