Guide Roller Device
Accurate introduction of the first forming wheel, with digital display, detection of head and tail of coils.

Lubrication system


The lubrication system for segment forming will be self-contained within the machine. The excess lubrication from the forming process will be re-circulated, filtered and re-used.

Special Gear Boxes Device
We optimized it and added a gearbox. The gears are in the gearbox to ensure sufficient lubrication, higher transmission accuracy and lower noise. The length accuracy we can achieve now can be guaranteed within 0.5mm.

Control System


There are manual/automatic operation modes. It has manual and automatic switching function: under manual state, it can be operated on a single machine for easy maintenance; under automatic state, it can be operated on the whole line and started sequentially; with emergency stop button, it is easy to deal with emergencies and ensure the safety of equipment and operators.

Manual operation panel beside the machine is convenient for workers to operate.




Q: What’s the diameter range your roll forming machine can do for clamps?

A: Min. diameter is 55mm, the max. diameter is 800mm.


Q: What products can this machine produce?

A: Auto V-band Clamps, ring clamps, G coulpings, Flanges, Gaskets, Aircraft Clamps


Q: What is the production speed?

A: Our company adopts servo motor, the speed can be controlled, according to the material thickness and diameter of the product, all of which can meet the requirements of customers.


Q: What are the advantages?

A: This roll forming machine we developed the latest technology to produce clamps, through one-time roll forming to complete, instead of the previous use of punch and other processes.
