The aluminum wire drawing process is a commonly used metal processing process in which aluminum is stretched and extruded to form the desired shape and size. This process is widely used in the manufacture of aluminum products, such as aluminum wire, aluminum tube, aluminum strip and so on. This paper will introduce the aluminum wire drawing process from the aspects of process flow, equipment requirements and application fields.

Process flow

The basic flow of aluminum wire drawing process includes raw material treatment, wire drawing processing, annealing treatment and surface treatment.

1. Raw material treatment: First of all, the aluminum needs to be pre-treated, including cleaning, drying and cutting. Cleaning can remove surface dirt and oxides to ensure the smooth progress of the drawing process.

2. Wire drawing process: the pre-treated aluminum is sent to the wire drawing machine, and the force of stretching and extrusion is used to make it gradually thinner and longer, while changing its cross-section shape. A wire drawing machine usually consists of multiple dies, each of which stretches the aluminum once until it reaches the desired size and shape.

3. Annealing treatment: In the process of wire drawing, aluminum will be subjected to certain stresses and deformation, in order to eliminate these stresses and improve the plasticity of the material, it is necessary to annealing treatment. The selection of annealing temperature and time has an important effect on the properties of wire drawing materials.

4. Surface treatment: The surface of the brushed aluminum is usually rough and needs to be treated to improve its finish and corrosion resistance. Common surface treatments include pickling, polishing and anodizing.

Equipment requirements

Aluminum wire drawing process requires a complete set of equipment to achieve, mainly including wire drawing machine, annealing furnace and surface treatment equipment

1. Wire drawing machine: Wire drawing machine is the most important equipment in the aluminum wire drawing process, which can transform aluminum into the required shape and size through the force of stretching and extrusion. Wire drawing machine is usually composed of feeding system, mold system and wire drawing system.

2. Annealing furnace: Annealing furnace is used for annealing aluminum after wire drawing to eliminate stress and improve the plasticity of the material. Annealing furnaces are usually electrically heated or gas-heated and have controllable temperature and time parameters.

3. Surface treatment equipment: Surface treatment equipment is used for cleaning, polishing and anodizing aluminum after wire drawing to improve its surface quality and corrosion resistance. Different surface treatment methods require corresponding equipment and process flow.

Application field

Aluminum wire drawing process has a wide range of application fields, mainly including the following aspects:

1. Electronic industry: Aluminum wire drawing materials are often used in the shell, wire and connector of electronic components. Aluminum wire drawing materials have good electrical and thermal conductivity, which can meet the performance and appearance requirements of electronic products.

2. Packaging industry: Aluminum wire drawing materials are often used in the packaging of products such as food, medicine and cosmetics. Aluminum wire drawing material has good sealing and corrosion resistance, which can effectively protect the quality and safety of packaging items.

3. Construction industry: Aluminum wire drawing materials are often used in building doors and Windows, curtain walls and decorative materials. Aluminum wire drawing materials are light, strong and weather-resistant, which can meet the building's requirements for material strength and appearance.

4. Automotive industry: Aluminum wire drawing materials are often used in the manufacture of automotive parts, such as body panels, radiators and exhaust pipes. Aluminum wire drawing materials have good strength and corrosion resistance, which can reduce vehicle weight and improve fuel efficiency. The aluminum wire drawing process is an important metal processing process that stretches and extrudes aluminum to form the desired shape and size. This process is widely used in the fields of electronics, packaging, construction and automotive to meet the requirements of different industries for material properties and appearance. The development of aluminum wire drawing process will further promote the application of aluminum products and the development of the industry.
