Copper clad aluminum machine is a class of industrial equipment specifically designed for the production of copper clad aluminum wire.
Copper clad aluminum wire is a kind of composite conductor material, using the light weight and cost advantage of aluminum, while combining the excellent conductive properties of copper, widely used in wire and cable, electronic components and other fields.
Process flow of Copper clad aluminum machine
The production process of copper clad aluminum involves several steps, mainly including raw material preparation → drawing → surface treatment → cladding (mechanical or thermal) → welding → straightening→ winding and packaging.
1. Preparation of raw materials
• Aluminum core material: usually use aluminum rod or aluminum wire, commonly pure aluminum or aluminum alloy (such as 1350 aluminum alloy).
• Copper cladding material: Usually high purity copper strip, copper foil or copper wire.
2. Aluminum wire drawing
• Aluminum rods or wires are drawn to the required diameter by means of a drawing machine.
3. Aluminum wire surface cleaning and treatment
• Use chemical or physical means to clean the surface of aluminum core, remove oxidation layer, oil and impurities, to ensure a close combination with the copper layer.
4. Copper cladding
• Copper cladding is the core step of the production process, the specific process can be divided into the following two ways:
• (1) Mechanical cladding: Using special cladding equipment, copper strips or foils are mechanically extruded onto the outer surface of the aluminum core to form a copper layer. After the copper tape is clad, it is usually necessary to weld the copper tape seams.
