High-Precision Fully Automatic Automotive Duct Production Line - China Suppliers & Factory for Efficient Manufacturing
Liding Why do professionals choose LIDING flange machines?
Super Efficiency & Big Labor Savings
This production line runs at up to 15 m/min, 2–3 times faster than standard semiautomatic machines. The whole process is fully automatic, only needing one operator, which cuts labor costs by more than 80%. It supports forward, reverse, emergency stop, and steady speed regulation, easily adapting to largebatch and smallbatch production.
Premium Materials & Long Service Life
We only use durable materials for core parts. Rollers can be upgraded to Cr12mov alloy steel with heat treatment up to HRC62–64°, wearresistant and 3 times longer service life than common steel. The heavyduty frame and largediameter shaft keep the machine stable under longtime highload running, with low failure rate and less maintenance.
High Precision Meets Industry Standards
Multistation continuous roll forming and imported control system ensure stable dimension and high straightness. The ducts have good air tightness and perfect fitting performance, fully meeting automotive and HVAC industry standards. No onsite modification, no material waste, greatly reducing installation cost and improving project quality.
Easy Operation & Reliable AfterSales
Equipped with an imported PLC touch screen, parameter setting is simple and clear. Workers can master operation in a short time without professional skills. We provide 1year warranty, free online technical support, and free replacement parts within the warranty period. Overseas engineers can go on site for installation, commissioning and training.
Standard Production Process
Decoiler Feeding → automatic leveling → punching & notching → multistation roll forming → precision straightening → fixedlength cutting → finished product discharging
Frequently Asked Questions
What is the production speed of the LIDING flange machine?
The production line runs at speeds up to 15 m/min, which is 2 to 3 times faster than standard semiautomatic machines, significantly increasing production output.
How does the machine save labor costs?
The entire process is fully automatic and only requires a single operator to manage, reducing overall labor costs by more than 80%.
What materials are used to ensure the durability of the rollers?
Rollers can be upgraded to Cr12mov alloy steel with heat treatment up to HRC62–64°. This makes them highly wear-resistant and offers a service life that is 3 times longer than common steel.
Does the duct output meet industrial ventilation standards?
Yes. The combination of multistation continuous roll forming and an imported control system ensures stable dimension, high straightness, and excellent air tightness that fully meet automotive and HVAC industry standards.
What is included in the after-sales service and warranty?
We provide a 1-year warranty, free online technical support, and free replacement parts within the warranty period. Additionally, overseas engineers are available for on-site installation, commissioning, and staff training.
What are the stages of the standard production process?
The automated process follows these steps: Decoiler Feeding → automatic leveling → punching & notching → multistation roll forming → precision straightening → fixedlength cutting → finished product discharging.
