Bow twister is the important equipment for wire and cable cabling, it is mainly used for control cables, low voltage cables, rubber sheathed cables, mining cables, overhead insulated cables and other products.
With the continuous decrease of wire and cable products’ profit, it is imperative to reduce the production cost for the manufacturers. And improving production efficiency is one of the effective ways to reduce production cost. With the unique structure, the production efficiency of bow twister is more than twice as much as the tubular stranding, and more than five times of cage stranding machine. Due to the advantages of high production efficiency, bow twister has been used more and more widely.
Our company has many years of experience in research and development of bow twister, integrates with the cabling production process of China first-class cable manufacturers fully. We can provide 630, 800, 1000, 1250, and 1600 types of bow twister. And we can provide 1+3, 1+4, 1+5, 1+6 various types of cabling according to customers’ needs, which effectively broaden the production range of product, and can meet the cabling up to 7 core cables. It is the best equipment for mass, continuous and efficient cabling.
1.The twisting bow is made of imported carbon fiber and glass fiber composite material with high strength, light weight, low noise during rotation.
2. Small moment of inertia and high speed.
3. Simple structure, convenient operation and maintenance.
4. 100% back twist can be achieved.

This equipment is mainly composed of central pay-off, guide frame, twister, die holder, traction device, traverser and electrical control system. Also can be equipped with wrapping device according to customer requirements.
1. The twister
The twister is the main component of the bow twister. Its quality affects the quality of cable directly. In particular, the arch material, need to meet the needs of high-speed rotation safety and stability, it will not only affect the product quality if fracture , but also will cause personal safety problems.
Our twister bow uses the imported carbon fiber and fiberglass composite material. And with the characteristics of high strength, good toughness, light weight, stable high-speed rotation, low noise, etc.
The two ends of the arch are supported in front and back by a bearing seat. Separated AC frequence motor drive, frequence control, and can rotate left and right through adjusting the rotation direction of twister bow.
The twister uses the unique design of streamlined construction, can make threading convenient. The insulation wire from pay off to the axle hole of twister bow ends. Then along the guider wheel of twister bow to the other end og axle hole for twisting. With the smooth guider wheel, the full process wire core path smoothly. Avoiding the cable core scracth efficiently.
The reel frame is end shaft type manual clamping or relaxing reel, with mechanical locking protection mechanism, which is reliable and safe.
The tension is controlled by mechanical friction, and the tension is adjustable. Magnetic powder or hysteresis tension control can also be used according to customer requirements.
The bow twister machine is equipped with 6 filling rope pay-off devices, which can be stranded together with the insulated wire core during production, effectively ensuring the roundness of the cable after cabling.
The range of cable pitch is wide, and can be adjusted infinitely, which is convenient to improve the production process.
The equipment is equipped with stop protection device for broken wire. If broken wire occurs in the production process, the equipment can stop in time to avoid a large number of unqualified products.
After the order is established, we will provide customers with foundation drawing, pipe drawing and layout drawing. Customers can build and lay foundations according to the drawings we sent.
We will discuss in detail with our customers about the commissioning plan before the equipment arrives at the factory. Customers need to prepare materials for installation and commissioning. Of course we will send a detailed preparation list to help our customers.
We will send two experienced engineers, including a mechanical engineer and an electrical engineer to guide the installation and commissioning. Engineers will try best to train the workers be familiar with the equipment.
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;
