Round Duct Grooving Machine — New | BLKMA, Ma'anshan, China

The BLKMA Round Duct Grooving Machine is used primarily for beading round pipes and connections, available in both manual and electric types to suit different production volumes and budgets. The machine can be equipped with special rolling wheels to create various workpiece shapes, including flange, envelope, mortise, and bead groove profiles, with custom-made special forming available according to specific customer requirements.

Widely used in the HVAC duct fabrication industry, this grooving machine is particularly well suited to producing small and nonstandard round ducts, offering economic and efficient advantages for fabricators working with varied duct specifications rather than pure high-volume standard production.

Why Choose This Round Duct Grooving Machine?

For small-batch or nonstandard round duct production, dedicated high-volume equipment can be inefficient or overpowered for the task. BLKMA's grooving machine is specifically positioned as an economic, efficient solution for this segment — with interchangeable rolling wheels allowing one machine to produce multiple profile types (flange, envelope, mortise, bead groove) rather than requiring separate dedicated machines for each.

BLKMA backs this product with CE certification, an established export history to Southeast Asia, the EU, South America, and the Middle East, and a 48-hour on-site service commitment — giving international buyers confidence in both product quality and after-sales support.

Manual types suit lower-volume or budget-conscious operations, while electric types offer faster, less labor-intensive operation — BLKMA offers both to match different production requirements.

What profile shapes can this machine produce?
With interchangeable rolling wheels, the machine can produce flange, envelope, mortise, and bead groove profiles, with custom special forming available on request.

Is this machine suited to high-volume standard production?
It's specifically positioned as ideal for small and nonstandard round duct production — for high-volume standard duct runs, BLKMA's other dedicated round duct machines may be more suitable.

What after-sales support is available?
BLKMA offers a 48-hour on-site service commitment, backed by an established export history and after-sales service across Southeast Asia, the EU, South America, and the Middle East.
