A bunching machine is a type of cable machine used in manufacturing to twist together several wires or strands of wire to form a cable. It is used to produce stranded cables with a higher number of wires or strands.
The bunching machine takes multiple wires, usually pre-insulated, and twists them together to form a cable. The wires are fed into the machine and then passed through a series of rotating arms or rollers, which twist them together to create the desired stranded cable.
Bunching machines can produce cables with various strand configurations, such as concentric or rope-lay stranded cables. The machine's speed and tension control the cable's twisting, ensuring the final product meets the required strength, flexibility, and electrical performance specifications.
Bunching machines are widely used to produce cables for power transmission, telecommunications, and electronics applications. They play an essential role in ensuring that the cables produced meet the required quality standards and specifications.
Single and Double Twist Bunching Machine:
The advantage of the single twist buncher is that the winding shaft rotates around its central axis.
The production speed to be achieved is much higher compared to a drum twisting machine. The single twist buncher limits the bending radius of the incoming individual product, just in case. The bending radius that can be achieved for a single wire is greater than the bending radius inside the single twister. Another production option must be chosen, e.g. a drum twister. The single twister can achieve good twisting results over the entire production length thanks to modern control technology.
The double twist buncher is twisted twice in turns on the bow. A take-up tube or reel is installed in a double twist buncher, and one bow rotates around the pay-off device. The individual product gains are outside the machine. The machine usually has a housing. In addition to the winding tube, the bobbin can be used as a pay-off device for a single wire. The individual elements are located on the outside of the machine housing. They are connected to a laying board at the front of the machine. Starting from the lay plate, they pass through the bow and add two twists before entering the spool or drum.
In Zhaohong, we have four types of bunching machines 300 Bunching Machine, 500 Bunchine Machine, 630 Bunching Machine and 800 Bunching Machine. Each of these type is designed specifically for the production of different types and sizes of cables
