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.
