Rectangular air duct fabrication
Supports the edge-forming stage used to prepare rectangular ventilation duct sections.
Ventilation duct workshop
Fits workshops that combine cutting, beading, lock forming, flanging, folding and seam closing.
Galvanized sheet folding
A practical forming method for suitable galvanized thin sheet used in ducts and light enclosures.

Material Review
Materials
Material strength, sheet thickness, bending length and pneumatic configuration must be reviewed together.
Galvanized Sheet
Common for rectangular HVAC duct panels and general ventilation work.
Mild Steel Sheet
Suitable when thickness, strength and folding length match the selected QS model.
Stainless Steel Sheet

Color Steel Sheet
Relevant to selected enclosure, architectural trim and ventilation applications.
Thin Metal Plate
Match material strength, bending length and air-driven machine configuration before production.
The suitable thickness depends on material strength, bending length, air pressure and machine configuration. Please confirm your material, thickness and bending requirement before quotation.
Utility Planning
Compressed Air Requirement
Confirm the available compressor before selecting the machine. Stable air supply is part of the production system, not an optional accessory.
01
Pneumatic folding requires a stable compressed air supply.
02
Air pressure and air volume should match the selected machine model.
03
Clean, correctly prepared compressed air helps protect the pneumatic system.
04
Before quotation, confirm whether your workshop already has an air compressor.
- Selection value
- Air pressure: Please confirm with our sales engineer
- Production value
- Air consumption: Depends on machine model and production frequency
