Hot rolled and continuous casting and rolling

Hot rolling and continuous casting and rolling is an efficient way to produce aluminum wire. First, the aluminum liquid is cast into aluminum bars through a casting mold, and then the aluminum bars are rolled into aluminum wire through hot rolling and continuous rolling processes.

• High production efficiency: Hot rolling and continuous casting and rolling can greatly increase production speed, reduce production cycle, and are more efficient than traditional casting and rolling methods.
• No joints and uniform structure: The hot-rolled aluminum wire has no joints in the whole coil, and the surface of the aluminum wire is smooth without coarse grain rings, which is suitable for cold heading fasteners in the fields of aerospace, high-speed railway, automobile, etc.
• Superior material properties: The aluminum wire produced by this process has a more uniform organizational structure and stable mechanical properties, making it suitable for the production of high-strength fasteners.
• Energy saving: This process can effectively reduce energy consumption and improve the energy efficiency of the production process.

Drawing process

Wire drawing is the most common method of producing aluminum wire, which is to stretch aluminum into wire by passing it through a die. This process can produce aluminum wires of different diameters and is usually used to produce cold-headed aluminum wire, conductive aluminum wire, etc.

• High Precision: The wire drawing process can precisely control the diameter and surface smoothness of the aluminum wire to meet the dimensional accuracy requirements of fastener applications.
• Strong flexibility: Aluminum wires of different specifications and shapes (such as round wires, flat wires, etc.) can be produced according to customer needs.
• Cost-effectiveness: The wire drawing process requires less investment in equipment, is suitable for mass production, and can effectively reduce production costs.

Extrusion process

Extrusion is the process of heating an aluminum rod to a certain temperature and then extruding aluminum wires of different shapes through a die. The extrusion process is often used to produce large-diameter aluminum wires or aluminum wires of complex shapes.

• Diversified shapes: The extrusion process can produce aluminum wires with complex shapes, such as flat wires, special-shaped wires, etc., to meet the needs of special fasteners.
• High Precision: The extrusion process can precisely control the size and shape of the aluminum wire, making it suitable for high-demand fastener production.
