Why Duct Manufacturing Is More Than One Machine
Ventilation duct production involves more than making a straight pipe. Real workshop efficiency depends on how duct forming, seam handling, fittings, flanging, cutting, and accessory production come together.
BOBO organizes this application around the workflows that matter in commercial, industrial, and residential ventilation manufacturing.
Application Scope
Duct Products and Workshop Scenarios We Support
This application is suitable for round spiral ducts, rectangular ducts, flexible aluminum ducts, semi-rigid ducts, elbows, reducers, tees, flanges, and selected air-filter related products.
It is especially relevant for HVAC contractors, duct workshops, industrial ventilation suppliers, and manufacturers building capacity for building ventilation systems.

Process Structure
A Practical Workflow for Duct Production
A typical workflow begins with coil feeding and duct forming, followed by seam processing, fitting preparation, and flange or corner production. Depending on the project, the workflow may also include elbow forming, flexible duct making, accessory fabrication, and filter-related assembly.
The right process path depends on the duct type, size range, connection style, and target output.

Key Machine Groups
Key Machine Groups for This Application
Spiral Duct Systems
For spiral duct forming, elbow processing, spiral fittings, oval tube forming, and related round-duct workflows.
Rectangular Duct Systems
For auto lines, lock forming, flange forming, zippering, corner processing, and rectangular duct assembly tasks.
Flexible Duct Systems
For flexible aluminum duct, clip air duct, and semi-rigid duct manufacturing.
Fan Flange & Accessory Equipment
For fan flange forming, disc spinning, corner punching, and related connection or accessory work.
Filter-Related Equipment
For air filter pleating, origami folding, sponge sticking, glue application, and selected support processes.

Frequently Asked Questions
Can BOBO support both spiral and rectangular duct production?
Yes. This application covers both spiral duct and rectangular duct workflows, along with fittings, flange-related processes, and selected accessories.
Do you also support flexible duct manufacturing?
Yes. We support flexible aluminum duct, semi-rigid duct, and related flexible air-duct production equipment.
Is this page suitable for a complete HVAC duct workshop plan?
Yes. It can be used as the starting point for customers planning a broader duct manufacturing workshop rather than buying only one machine.
