Why do professionals choose LIDING flange machines?
24-station progressive forming – why more stations mean higher precision
This machine utilises 24 sets of rollers, representing an upgraded configuration from the standard 18 stations. The increased number of roller stations means a smaller amount of deformation per station; stress is fully released during the gradual bending process, minimising springback, and the final forming precision is significantly higher than that of solutions with fewer stations. Key benefit: High precision ensures consistent flange dimensions, eliminating the need for trimming during on-site assembly and directly improving installation efficiency.
30 Years’ Experience in Cold Rolling + Globally Proven Track Record
Liding’s core team has specialised in the cold-forming sector for over 30 years. Our high-specification TDC flanging machines have been exported to more than 50 countries worldwide, with cumulative shipments exceeding 2,000 units. The equipment is CE-certified, and core components utilise international brands (such as Panasonic/Siemens PLCs and Schneider Electric), ensuring compliance with standards across major global markets. Core Values: Proven design solutions, reliable mass delivery capabilities and a comprehensive global after-sales support system – you are purchasing a mature piece of equipment that has been validated by the global market.
Servo Flying Saw Closed-Loop Control — Why Accurate Cutting Is Possible Without Stopping the Machine
Traditional pneumatic sawing requires the sheet to be stationary during cutting, resulting in time loss with every stop and start. This machine utilises a servo flying saw; the system tracks the sheet’s feed speed in real time, performing fixed-length cuts during continuous operation, whilst continuously correcting the cutting position via closed-loop feedback. Core Value: Cutting length tolerances are controlled within ±0.5 mm/m; the cut edges are smooth and burr-free, eliminating the need for secondary trimming and resulting in higher material utilisation.
Gearbox Transmission + Forced Cooling — Why It Can Operate Stably for Extended Periods
Gearbox transmission replaces chain drive, completely eliminating the problem of chain stretch and wear caused by long-term operation, and eliminating the need for regular tension adjustments. The PLC control console is equipped with a dedicated cooling system, providing forced cooling in high-temperature workshop environments to prevent the control system from crashing due to overheating or component ageing. Core value: a maintenance-free transmission system combined with temperature-controlled protection supports 24-hour continuous production, significantly extending the annual effective operating time.
Standard Production Process
Decoiler → feeding → 24-station continuous roll forming → precision sizing and straightening → Fly-cutting 12/min with servo motor → finished product discharging
Frequently Asked Questions (FAQ)
What are the advantages of 24-station progressive forming over standard 18-station machines?
The 24-station configuration distributes deformation more gradually across additional roller sets. This reduces stress per station, minimizes metal springback, and yields substantially higher dimensional precision, eliminating on-site trimming and improving installation efficiency.
How does the servo flying saw achieve non-stop continuous cutting?
The servo flying saw synchronizes in real time with the sheet metal feeding speed using closed-loop feedback. It cuts at preset lengths on-the-fly with a speed of up to 12 cuts/min and a precision of ±0.5 mm/m without interrupting line operation.
Why does LIDING use gearbox transmission instead of chain drives?
Gearbox transmission eliminates common chain-drive issues such as chain stretch, wear, and frequent tension adjustments. This provides a maintenance-free mechanical foundation capable of supporting heavy-duty, 24-hour continuous production.
How does the forced cooling system protect the electrical console?
The PLC control console incorporates a dedicated forced cooling unit that prevents high workshop temperatures from overheating core components, avoiding system crashes and extending the lifespan of electronics.
What international certifications and key component brands are used?
LIDING equipment is CE-certified and incorporates premium global brands including Panasonic and Siemens PLCs, as well as Schneider Electric electrical components, ensuring compliance with global market standards.
What is the full standard workflow of the flange forming line?
The standard automated workflow includes: Decoiler → Feeding → 24-station continuous roll forming → Precision sizing and straightening → Servo fly-cutting (12/min) → Finished product discharging.
