Wire drawing dies are essential tools in the wire and cable manufacturing sector that are used to reduce the diameter of the metal wires and increase their length. The process includes pulling a wire through a hole which is found in a special tool called a die with a specific diameter. What follows is a step-by-step overview of the wire drawing process:
Material Selection
The choice of wire drawing die depends on what material is being drawn out, such as copper, aluminum, steel or any other alloys. Different materials are characterized by different properties that necessitate special die materials for maximum efficiency.
Die Design
Typical materials used in making wire drawing dies include tool steel, Tungsten carbide, or diamond; tungsten carbide and synthetic diamond are the commonly used ones. Single crystal diamond dies can be used to draw very fine wires. To draw wire properly through a hole during the operation of drawing, die design is crucial.
Lubrication
Friction reduction and prevention of damage to both the wire itself and also to die occur due to lubrication during the process of Wire Drawing. These may entail various methods like immersing copper sulfate solution into it or using specialized lubricants.
Either cleaning, coating, or annealing can also be applied to drawn wire depending on its use to enhance its properties and enable it to perform well in specific industries.
Application of Wire Drawing Dies in Different Industries
The employment of wire drawing dies is observed from various sectors which include telecommunications, automobiles, aerospace, electronics among others. The nature of the wires is determined by the requirements of the industry and the application of the wire they are meant for. Here are some examples showing how useful wire drawing dies are different industries:
