Round Duct Flange Making Machine


Brief Introduction- Angle Steel Round Flange Making Machine 
The Angle Iron round flange profile is as an integral part of light steel frame is roll-formed from Hi-Tensile GI steel. With its advantage, it is very popular in the present market, The Steel angel is widely adopted in Building construction Industry – commercial and residential. The normal thickness of L angle can be from 1-5mm.
Our Angle steel round flange making machine change the traditional flange production way, The most advantage of this hydraulic angle steel flange machine is the production efficiency increased and the labor cost reduced too much. With its high efficiency, safety and reliability, it is very popular in the present market.
■ Main Parameter - Angle steel Round Flange making machine
The angle steel round flange making machine is including three parts production deice as following,
- Round Flange roll forming machine
 The round flange with rivet holes can be finished by this roll forming machine, the raw material is GI Steel coil.
- Round flange holes punching machine 
 The round flange connection holes can be processed by this machine, it is controlled by servo system.
- Welding machine
 Before Punching connect holes on the flange, the round flange needs to be welded, so that to guarantee the exact holes position on round angle flange.
