Stranding Machine:
A stranding machine is primarily used to twist multiple wires or strands together to form a cable. It is commonly used for high, medium, and low voltage cables, as well as automotive wires [1]. The stranding process involves twisting individual wires or strands around a central core to create a cable with enhanced strength and flexibility.

Bunching Machine:
A bunching machine, on the other hand, is used to assemble multiple wires into a bunch or strand. It is commonly used in the construction of multi-conductor cables. The bunching process can be carried out with flexible or rigid wires, and with either bare or insulated conductors. Bunching machines can be categorized into single twist and double twist machines.

Single Twist Bunching Machine: This type of machine spins the take-up reel around its center axis. It is suitable for stranding individual products with a small bending radius. Modern control technology allows single twist machines to achieve good stranding results throughout the production length.

Double Twist Bunching Machine: This machine makes two twists in turn of the wire bundle. The elements to be bunched are placed outside the machine housing and pass through the lay-plate before going through the bow, where the twists are added. Double twist bunching machines are commonly used for stranding multi-stranded copper wires, tinned wires, enameled wires, and copper-clad aluminum wires. They can also be used for laying up multiple cores of small size building wires.

Bunching Machine Typical Applications:

BM-300: Earphone cables, USB cables, Ethernet cables.
BM-500: USB cables, automotive cables, HDMI cables, power cords, speaker wires.
BM-630: Automotive cables, power cords, fire alarm cables.
BM-800: Automotive cables, power cords, submersible/welding cables.
BM-1000: Power cords, submersible/welding cables.
BM-1250: Power cords, flexible conductors, submersible/welding cables.
