The first stage in the production process is the selection and preparation of the copper conductor. High-purity copper rods are used as the raw material. These rods are inspected for purity and quality before being drawn into wires of the required diameter. The drawing process involves pulling the copper rod through a series of dies with decreasing diameters, which reduces the cross-sectional area of the rod and increases its length. This process also work-hardens the copper, improving its mechanical strength. The drawn Copper Wire is then annealed, a heat treatment process that softens the copper and reduces internal stresses, ensuring that it has the required ductility and conductivity.

Once the copper conductor is prepared, it moves to the insulation extrusion stage. The PVC Insulation Material is first compounded, which involves mixing PVC resin with various additives such as plasticizers, stabilizers, pigments, and flame retardants. These additives are carefully selected to enhance the properties of the PVC, such as Flexibility, heat resistance, and flame retardancy. The compounded PVC is then melted and extruded over the copper conductor using an extrusion machine. The extrusion process is highly controlled, with precise temperature settings and speed adjustments to ensure that the insulation is applied uniformly and adheres tightly to the conductor. The thickness of the insulation is monitored continuously during extrusion to ensure it meets the specified requirements.

After extrusion, the Insulated Wire undergoes a cooling process to solidify the PVC insulation. This is typically done by passing the wire through a water bath or a series of cooling rollers, which rapidly cool the insulation and set its shape. Once cooled, the wire is wound onto spools or reels, with the length of each spool depending on the specification of the wire. For example, smaller specifications may be wound onto spools of 100 meters or 500 meters, while larger specifications may be wound onto larger reels to accommodate their heavier weight.

The next stage is quality inspection, which is carried out at various points throughout the production process. During the drawing and annealing stages, samples of the copper conductor are tested for conductivity, tensile strength, and ductility. During the extrusion process, the insulation thickness, diameter, and appearance are inspected continuously. After cooling and winding, the finished wire is subjected to a series of tests, including voltage withstand tests, insulation resistance tests, and mechanical tests. These tests ensure that the wire meets the required electrical and mechanical properties and is free from defects such as cracks, bubbles, or uneven insulation.

Finally, the approved wires are labeled and packaged for shipment. Each spool or reel is labeled with information such as the product name, specification, length, voltage rating, and manufacturing date. This information helps customers identify and select the correct wire for their applications.
