LIDING Why do professionals choose LIDING flange machines?
Unmatched Production Efficiency & Labor Savings
Our square duct production line runs at 10m/min, 2–3 times faster than standard semi-automatic machines. Fully automatic one-stop production only requires 1-2 operators, cutting labor costs by over 80%. It supports forward, reverse and emergency stop functions to perfectly fit various production speeds and batch processing demands.
High-Grade Materials & Long Service Life
Core rollers adopt high-quality GCr15 steel, optional CR12MOV alloy steel heat-treated to HRC62–64°, offering excellent wear resistance and 3x longer service life than common carbon steel rollers. 45mm 45# steel shaft ensures stable high-load long-term operation. Precision-machined cutting blades deliver clean, burr-free cuts without frequent replacement.
Precise Forming Meeting International Standards
Multi-station continuous roll forming with optional servo fly-cutting ensures accurate duct dimensions and stable structure. High forming accuracy and good air tightness strictly meet international HVAC duct standards, eliminating on-site rework and greatly reducing material waste and installation costs.
Intelligent PLC Control & Easy Operation
Imported PLC control system, converter and touch panel enable simple one-click parameter setting. No professional technical skills required. International brand electrical parts guarantee stable performance, low failure rate and easy daily maintenance. We provide free online technical support and replacement parts during the warranty period.
