Round Flange
Making Machines
Buyers searching for a round flange machine factory in China can contact WinYing, a China-based machinery supplier, to confirm the actual manufacturer and production arrangement for the quoted model. Explore round flange making equipment to form, punch and weld circular flanges for round HVAC duct connections. This round flange production line uses three complementary machines rather than one fully automatic unit. Plan three complementary machines around your flange drawings, material and production requirements.

THE COMPLETE PRODUCTION WORKFLOWFive stages.
Five stages.
One finished circular flange.
See how the three machines work together, from prepared material to a finished flange ready for round duct connections.
02 / FORMING
Form the flange
Feed, form, roll and cut the strip to the required ring size.
03 / PUNCHING
Punch the holes
Position the flange and punch the specified bolt-hole pattern.
04 / WELDING
Weld the joint
Clamp and weld the ring ends to complete the flange.
05 / FINISHED FLANGE
Inspect the finished flange
Check diameter, roundness, holes and the finished joint.
3 COMPLEMENTARY MACHINES / ONE COORDINATED PRODUCTION ROUTEProcess sequence and tooling follow the confirmed flange drawing.
THREE MACHINES · ONE FINISHED FLANGE
Equipment for each production stage
Compare circular duct flange machine options: flange forming equipment, CNC flange punching and ring-end welding for round HVAC duct connections. This production route differs from TDF and TDC panel-edge flange systems used for rectangular ducts. Confirm the machine sequence, material capacity and tooling together against your flange drawing.

Specifications are reference values from the supplied equipment information. Confirm capacity, flange profile, tooling and material compatibility for each of the three machines; their diameter and thickness limits are not identical.
PLAN YOUR PRODUCTION
Start with the flange drawing
Material & profile
Specify steel grade, thickness, flange width and the required cross-section.
Diameter & hole pattern
Provide ring diameters, bolt-circle dimensions, hole sizes and hole quantity.
Output & workshop
Share batch quantities, available space, power supply and destination.
Round flange production questions
Do I need all three machines?
The three machines cover forming, punching and welding. Select the supply scope around the equipment and processes already available in your workshop.
Can one tooling set cover every flange size?
Confirm the tooling and size changes for each machine against your drawing and required diameter range.
What should I send for a quotation?
Send material grade, thickness, flange drawing, hole pattern, required output and power supply.
