Product Details

During the production of wires and cables, multi-strand conductors need to be twisted before the insulation extrusion.The stranding of multi-strand conductors can be carried out by stranding machine or bunching machine. When the diameter of single wire is very small and the stranding finished wires with extra-soft performance, then you can only use the twisting machine instead of traditional stranding equipment.
Wires from a number of single-wire pay-off bobbins which are layered and arranged on the fixed stand will enter into the main engine through the dividing plate.
The single wire is twisted by the rotation of rotating body to complete the twist stranding of conductors.
The twist buncher provided by us can be used for stranding bare copper, tin-plated copper, silver-plated copper, copper-clad aluminum wire, special alloy wire, insulated core wire.
Our twist buncher machine can not only carry on the bunch stranding of the multi-strand conductors, but also can carry on regular stranding by replacing stranding with bunching.
It can replace (1+6) tubular stranding machine and (1+6) rigid frame strander. Compared with the tubular stranding machine, the double twist buncher machine has 2 ~ 4 times capacity than it.

1. Equipment Features

(1). With variable frequency speed regulation way and touch screen control,convenient and efficient for operation
(2). The magnetic powder clutch controls the winding tension, the PLC automatically track winding line adjust tension , and the winding tension is constant without fluctuation.
(3). Using the electromagnetic brake to brake, internal and external wire break, various fault automatic brake.

2. Main Technical Parameters







Max. rotation speed (rpm)






Inlet wire diameter (mm)






Stranded outer diameter(mm)






Stranded cross-sectional area(mm²)

3. Bunching Effect

Bunching Effect

Our high speed double twist bunchers can meet bunched requirements of different specification.It has the characteristics of high speed, high efficiency, light weight, small floor area, low noise and high quality bunched product.

    Main Components

    The machine is mainly composed of pay-off device, frame structure, twisted power, transmission, wire bobbin, main axis bearing base, main axis bearing lubrication system, take-up line device.

    Buncher machine1. Pay-off Device

    It can be equipped initiative or passive pay-off frame
    1.1 Multi-head Active Pay-off Frame

    Multi-head Active Pay-off Frame
    Suitable for the workplace where need precise control of wire tension and larger bobbin weight , it can automatically track the take-up speed and provide the constant tension that process required.
    1.2 Vertical Constant Tension Active Pay-off Frame

    Vertical Constant Tension Active Pay-off Frame
    It can automatically track the take-up speed and provide constant tension.Tension adjustment is achieved by adjusting the pressure of compressed air.Automatic emergency braking is available when stopping and disconnecting.
    In addition, our company can also provide unilateral double-head active pay-off frame, bilateral double-head active pay-off frame, vertical passive pay-off, horizontal stationary pay-off, etc., to meet the technical requirements of different products twisted wire pay-off.

    2. Twisting Bow

    Twisting Bow
    Using imported carbon fiber material. Special shape, can reduce the wind resistance. When running at high speed, the equipment has low noise and good stability when running at high speed.

    3. Traversing Unit

    Traversing Unit
    Tailor-made bi-directional line unit, smooth rod bearing type traverse, row width, row distance can be precisely adjusted.

    Installation and Commissioning

    After the order established, we will send our customer the layout drawing, circuit diagram & PLC wiring diagram, and the operating instruction. Customer can make the site planning according to the drawing we provided.
    When the equipment is about to be completed, the two parties will communicate in detail on the commissioning plan. Customer should get all the things ready before our engineer arrives. After the engineer arrives at the scene, he will meet with the customer to communicate the commissioning plan, the required expenditure and the estimated completion time. After the installation finished, the engineer will start the equipment with no-load test and full-load test. During the bunching, the engineer will train the customer ’s workers, and at the same time, the engineer will also tell them the problems they often encounter in the process and the effective solutions. We will try our best to support the workers be familiar with the entire production line.

    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.
