lidingWhy 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.

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.
