A copper wire bunching twist machine is a specialized piece of equipment used in the wire and cable manufacturing industry to twist together multiple copper wires into a cohesive bunch or strand. Bunching or stranding is a crucial process that enhances the flexibility, strength, and conductivity of copper wires, making them suitable for various applications.
Copper wire bunching twist machines are used to produce stranded conductors for a wide range of applications, including power cables, control cables, communication cables, and more. The twisting process enhances the wires' mechanical properties and allows for flexibility while maintaining good electrical conductivity.

3. Key features and functions of a copper wire bunching twist machine include:
1. Wire Pay-off System: The machine typically has a wire pay-off system that feeds multiple copper wires from individual spools or bobbins into the twisting area.
2. Twisting Section: In the twisting section, the copper wires are twisted together using rotating spindles or bobbins. The machine can adjust the twist pitch and direction according to the desired specifications.
3. Tension Control: Proper tension control ensures uniform twisting and prevents wire breakage during the bunching process.
4. Speed Control: The machine allows operators to adjust the twisting speed to achieve the desired twist density and overall wire properties.
5. Take-up System: After the bunching process, the twisted copper wires are wound onto a spool or bobbin for further processing or packaging.
6. Control Panel: The control panel provides operators with the ability to set and monitor various parameters, such as twist settings, tension, and speed.
7. Safety Features: Bunching twist machines may include safety interlocks, emergency stop buttons, and protective enclosures to ensure operator safety during operation.
8. Customization: The machine can accommodate various wire diameters, numbers of wires, and twisting configurations, making it versatile for different applications.
4. Machine main electric brand

Low voltage electrical parts: Adopts SIEMENS, OMRON, brands,etc.
Technical Features
1. The main shaft's maximum rotation speed is 2500 rpm.
2. When twisting the wire, the wire tension needs to be continuously increased when the wire is received from the bottom of the bobbin. The machine can automatically track and adjust the take-up tension to ensure the tension of the whole wire is even and uniform, and the machine can adjust the tension without stopping.
3. The main engine is oil-lubricated and naturally circulated and cooled, which effectively extends the service life of the main shaft bearings.
4. The wire-passing system adopts a new structure, and the wire is directly passed from the main shaft guide wheel to the bow band, so the scratching and jumping phenomenon caused by the failure of the corner guide wheel on the aluminum wheel is subtracted.
The bearings of the whole machine are all well-known Japanese brands.
5. The bow belt is made of new materials and has good flexibility. In high-speed operation, it avoids jumping stock caused by vibration. Inverter, PLC, magnetic powder clutch, electromagnetic brake, hydraulic jack, etc are all imported famous brands to reduce the failure rate and maintenance costs.
