Manufacturing Processes of Enamelled Aluminium Wire

The production of enamelled aluminium wire (commonly known as magnet wire) involves a series of meticulously controlled stages, each critical to ensuring high-quality output suitable for demanding industrial applications.

1. Material Preparation:
The process begins with the selection of high-purity aluminium alloys, typically 1350 or 1370 series, with a minimum aluminium content of 99.5%. The raw aluminium is cast into billets, which are then hot-rolled into thin strips or wires. To achieve the desired diameter and mechanical properties, these wires undergo cold-drawing, involving multiple stages of drawing through progressively smaller dies. Lubricants and drawing oils are applied during this process to reduce friction and prevent surface defects.

2. Forming and Drawing:
The wire drawing process is central to achieving precise diameters with tight tolerances. Each drawing pass involves pulling the wire through a die, which reduces its diameter incrementally. Between passes, annealing is performed—typically in a controlled atmosphere furnace—to restore ductility and relieve internal stresses. This step is crucial for maintaining the wire’s flexibility and preventing breakage during subsequent processing.

3. Insulation Application (Enamelling):
The core of the manufacturing process is the application of the enamel insulation. The wire is coated with a thin, uniform layer of high-temperature, electrically insulating varnish or polymer. This is achieved through methods like dip-coating, where the wire is immersed in a liquid varnish and then dried, or spray-coating for more precise layer control. Multiple layers may be applied to meet specific insulation thickness requirements, with each layer being cured in an oven at temperatures typically ranging from 150°C to 200°C. The choice of enamel formulation depends on the intended application—high-temperature resistance, flexibility, or chemical stability.

4. Curing and Finishing:
Post-application, the coated wire undergoes a curing process to solidify the enamel and ensure adhesion. This involves passing the wire through controlled-temperature ovens, where the solvent evaporates, and the enamel cross-links to form a durable insulating layer. Once cured, the wire is tested for uniformity and insulation integrity before spooling.
