How to reduce the diameter of metal wires – Wire Drawing Machinery
What Is Wire Drawing Machinery
Metal wire drawing machinery is a type of metal processing equipment that is mainly used to perform plastic deformation on metal wire through a drawing die, in order to obtain the desired diameter of metal wire. It consists of a host, wire drawing die, traction device, wire winding device, cooling system, etc. Usually used in industries such as mechanical manufacturing, hardware processing, precious metal jewelry processing, artistic metal processing, and wire and cable manufacturing.
Metal wire drawing machines include small wire drawing machines, single-eye wire drawing machines, double-eye wire drawing machines, 8-eye/12-eye wire drawing machines, etc. These devices can draw metal raw materials into the required fine wires through strong traction force according to different wire diameter requirements and material characteristics, thus meeting the production needs of various specifications of metal wires.
The working principle of the metal wire drawing machinery is to fix the wire drawing die through the host, pass the metal rod material through the wire drawing die, and under the traction of the traction device, enter the wire winding device after a certain length of travel, and be wound into a wire of a certain diameter by the wire winding device. During the wire drawing process, the cooling system continuously sprays coolant onto the metal wire to maintain a lower temperature, thereby avoiding the phenomenon of hardening and deformation of the metal wire.
Drawing Process
Wire drawing is a metal processing technique that reduces the cross-section/diameter of a wire by pulling it through one or more wire drawing dies. Wire drawing has many applications, including wires, cables, tension-loaded structural components, springs, paper clips, wheel spokes, and string instruments.
The wire drawing machinery usually changes the diameter or shape of the wire from the disk to the disk through the wire drawing die to move the required diameter or shape. The wire must be lubricated when it enters the drawing die, and the drawing die has dedicated cooling (usually water-cooled jacket cooling). The closing machine provides power.
The drawing process is conceptually very simple: by hammering, filing, rolling, or forging, the starting part of the rod is first shrunk to allow it to pass through the wire drawing die. Then the wire enters the drawing chamber through the pay-off frame and is stretched through the tower wheel and drawing die. When the wire is pulled through the drawing die, its volume remains unchanged, so as the diameter decreases, the length increases.
Usually, the wire needs to be pulled multiple times and passed through continuous smaller drawing dies to achieve the desired size. The cooling method of wire rod drawing is spraying and half soaking. Then it passes through the constant speed wheel and then the traction wheel to enter the take-up reel. The stretching tower wheel is arranged horizontally in a single row.

How To Choose The Appropriate Wire Drawing Machinery
Commercial wire drawing usually starts with a metal rod with a diameter of 9mm (0.35 inches), and then obtains the final required size of fine wire through a wire drawing machine. CDOCAST can provide different wire drawing machines based on the diameter and thickness of the drawn wire to meet customers’ needs for different specifications of wire:
1. Small single-eye wire drawing machine
CDOCAST small single-eye wire drawing machine is suitable for drawing metal wires such as gold, silver, copper, platinum, etc. Compared to large single-eye wire drawing machines, small single-eye wire drawing machines have limited drawing force and production capacity, making them more suitable for processing smaller and shorter wires. The design power of this device is usually 4-5kW, and it can pull out thin wires with a diameter range from 2.2mm to 0.2mm. The main features of a small monocular cable pulling machine include good stability of the body, resistance to deformation, fast speed, small size, and easy mobility.
2. 8-12 eye wire drawing machine
Compared to single-eye wire drawing machines, CDOCAST multi-eye wire drawing machines have multiple wire holes that can process multiple wires simultaneously, greatly improving work efficiency. It can pull wires with a diameter range of 2.2mm to 0.2mm. It is usually used in the production process of jewelry and precious metal, and is suitable for jewelry-making processes that require delicate operations.
3. Large single-eye wire drawing machine
Compared to small single-eye wire drawing machines, CDOCAST’s large single-eye wire drawing machine is designed with stability in mind, ensuring that it is not easily deformed under long-term high-load working conditions, and guaranteeing the stability and reliability of the wire drawing process. Its powerful pulling force can handle various types of wires, including metal wires such as gold, silver, and copper wires, with a wider range of wire diameters from 9mm to 0.2mm. The drawing process of this machine is smooth, thanks to its high-precision design and high-quality materials, ensuring that it is not easily broken during the drawing process.
4. Single-eye wire drawing machine with servo motor
CDOCAST Servo motor wire drawing machine is equipped with Siemens PLC and servo motor, which can achieve precise control and fast response of wire drawing, ensuring the accuracy and stability of the wire drawing process. The machine power is 4KW, and equipped with take-up reels on left and right sides, which can be used for forward or reverse drawing without disassembling the take-up reels, greatly reducing the complexity of multiple drawing processes.
