Product Introduction Related Products

Air duct rolling equipment is mainly used for rolling forming of passenger car cold air duct. Generally, it is designed and produced according to customer's air duct cross-sectional shape, size and technical requirements. It is a special non-standard equipment.

Air duct rolling equipment is part of DUOYUAN's work on roll forming and skin-panel equipment for bus and commercial vehicle bodies. The page shows the equipment family and project images. Rated load, speed, material range and cycle time are confirmed in the engineering review for that vehicle and plant. They are not fixed catalog values.

Questions before a technical review

What is confirmed before a roll forming line is built?
Panel or profile shape, material and thickness are taken from the buyer's part drawings. Those values are not listed here as a universal machine range.
Are capacity, speed and material range published as fixed specifications?
No. DUOYUAN confirms rated load, line speed, material grade and cycle time during the engineering review. A category page does not state a payload, thickness or tolerance that applies to every project.
What should a buyer send with an inquiry?
Send the vehicle or part, the process step, the target plant and any layout constraints to info@zzdy.cn or call +86-371-62138138. The engineering team replies with the project scope. Do not treat marketing copy on this site as a guaranteed technical parameter.
