Concentric stranding machine is a new type of high speed stranding machine, mainly used for stranding, drawing and pressing of the large length copper strand, aluminum strand, aluminum alloy strand and other circular conductor, can also be used for stranding / pre-twisting and pressing of sector-shape conductor.
The concentric stranding machine can replace the rigid strander of some specifications and models.
It have two configuration modes: single-bobbin mode and double-bobbin mode.
Single-bobbin mode is equipped with one wire accumulating bobbin. After the wire on the accumulating bobbin is finished payoff and stranding, the wire need to be rewind onto the bobbin. In this mode, the rewinding process and stranding process cannot be performed at the same time, and the production efficiency is reduced, but the length of the equipment is shortened, and cost is reduced.
Double-bobbin mode is equipped with two wire accumulating bobbins. When one wire accumulating bobbin is used for pay-off and stranding, the other is rewinding. In this mode, rewinding process and stranding process are performed at the same time, and the production efficiency is high.
1. The pay-off rack has a large accumulation capacity and is suitable for the stranding of large-length single conductors.
2. Because the cage adopts a concentric structure, the rotation speed is high, the twisting speed is fast, which improves the production efficiency.
3. The bobbin is built into the equipment, there is no need to load or unload the bobbin, which greatly reduces the labor intensity of workers.
4. Using the stranding method of releasing multiple wires, each bobbin can release three or more wires. The equipment has a compact structure and saves floor space.
5. The payoff and takeup of the wire accumulating bobbin is driven by a separate AC servo motor, controlled by frequency conversion, and the tension is stable, accurate and adjustable.
6. It has a compact and reasonable structure with less wearing parts, so it reduce the cost of maintenance.
7. Less noise. Environmental friendly.

Q: Can I visit your factory?
A: All the customers from both home and abroad are warmly welcomed to visit our company and factory.
Q: Do you supply the installation and commissioning?
A: Yes, we do as followings:
-As soon as customer informed us the machines are put in the right place, we will send both mechanical and electrical engineer for machine start up.
-No-load testing: After machine installed completely, we make no-load testing first.
-With-load testing: Usually we will can produce 3 different wires to make load testing.
-Acceptance report: After the buyer confirms that machine can reach all specification under contract, the acceptance report will be signed for our record that machine will be in guarantee period.
Q: What information should I offer to get a detailed quotation from you?
A: For single machine: Usually we need to know inlet wire size, outlet wire size to be produced, productivity, pay off and take up size to choose the right machine.
For new cable plant or new cable production line, we need to know the datasheet of cables to be produced, the productivity, the standards to be followed, etc to design all machines needed.
Q: Can you supply the auxiliary equipment along with the machines?
A: Yes, definitely.
We has supplied heat exchanger, copper/aluminum powder filter machine, cooling tower, chiller, air compressor, drawing dies, pointing machine, cold welders, bobbins etc. with our machines.
Q: Could you do the design for the whole plant?
A: Yes, this is our advantage.
With the data sheet of cable to be produced, the standard your cables should follows, the productivity you expected. Our engineer on production technology and machinery will make design of production machines, test equipment, accessories like bobbins, dies, rewinding lines and materials needed.
Q: How can I know the status of my order?
A: We have our OA system on tracking the production.
For any of your request we can send photos and videos of your order, also we can use FACETIME to let you know the production.
Q: How do you work on the inspection before delivery?
A: We will make dynamic balance testing, levelness testing, noise testing, etc. during production.
After production finished, usually we make no-load running of each machine before delivery. Customers are welcomed to attend the inspection.
Q: What exhibitions will you attend, can we meet in the fair?
A: Dusseldorf International Wire and Cable Fair;
Wire South America Fair;
International Wire and Cable Fair in Shanghai;
International Istanbul Wire Fair, etc.
wire Southeast Asia Fair, etc.
