High-Quality PDF Steel Coil Flange Profile Machine from China Suppliers | Efficient Factory Production for HVAC Systems
Why do professionals choose LIDING flange machines?
Easy To Operate & Fully Automatic Control, Big Labor Savings
This production line adopts an imported PLC control system with an industrial touch screen operation interface, all parameters are visualized and adjustable, and common duct specifications can be saved as one-click presets. No need for professional senior technicians, ordinary workers can fully master the equipment operation after a short period of training, and one worker can manage the whole production line, which cuts labor costs by more than 80%. The whole process is fully automatic, supporting forward, reverse, emergency stop, and stepless speed regulation, easily adapting to large-batch and small-batch customized production.
Heavy-Duty Industrial Structure & Long Service Life
The equipment adopts a 24000*3800*1300mm overall heavy-duty welded frame with a net weight of 10000kg, which is welded with thick steel plates as a whole and undergoes strict stress relief treatment, ensuring no deformation or shaking during long-time high-load continuous operation. The 30kw high-power power system ensures stable power output during continuous production. The core forming rollers are made of high-quality GCr15 bearing steel, which can be upgraded to Cr12mov alloy steel with heat treatment up to HRC62-64°, with super wear resistance and 3 times longer service life than ordinary steel, low failure rate and less maintenance in the whole life cycle.
High Precision Forming & Fully Meet Industry Standards
Multi-station continuous roll forming structure and imported high-precision control system ensure stable dimensional tolerance and high straightness of the finished ducts. The formed flange joints are tightly fitted with zero air leakage, no on-site modification, no material waste, greatly reducing installation cost and improving project quality. The whole machine complies with CE and ISO international standards, and the finished products fully meet the strict requirements of commercial HVAC engineering, fire protection engineering and industrial ventilation projects.
Reliable Global After-Sales & Full-Process Quality Assurance
We provide full-process quality assurance for each equipment: raw material incoming inspection, production process full inspection, pre-delivery full-load test run, and we provide video outgoing-inspection and complete machinery test report for each machine before delivery. We provide 1-year full warranty for the whole machine, free online technical support for life, and free replacement of defective parts within the warranty period. Our after-sales engineers are available to service machinery overseas, providing one-stop on-site installation, commissioning and operation training services for global customers.
