The manufacturing process of cable copper tape usually includes the following main steps:

1. Raw material preparation

• Copper material procurement: Choose high-quality copper ingots or copper billets, ensuring they meet industry standards.
• test：Test the chemical composition and physical properties of raw materials to ensure they are suitable for subsequent processing.

2. Melting and casting

• Smelting: The copper material is melted in a high temperature furnace to remove impurities.
• Casting: The molten copper is cast into shape, usually using mold casting technology, to form a preliminary copper billet.

3. Rolling

• Hot Rolling: The cast copper billet is hot rolled at high temperature to initially change the shape of the copper and reduce its thickness.
• Cold Rolling: After hot rolling, it is further cold rolled to achieve the required thickness and width, increase the strength and surface finish of the material.

4. Annealing

• Annealing: Annealing is performed on the rolled copper strip to eliminate internal stress and improve the ductility and plasticity of the material.

5. Surface treatment

• Cleaning: Remove surface impurities and oxides to ensure the effectiveness of subsequent treatments.
• Surface coating：The copper strip is surface treated as required, such as tin plating, nickel plating or silver plating, to improve corrosion resistance and conductivity.

6. Cutting and forming

• Cutting: Cut the copper strip to the required length and width according to the customer's specifications.
• forming: If special shapes of copper strip are required, further stamping or bending may be performed.

7. Testing and quality control

• Detection：Test the physical and chemical properties of finished products, including thickness, width, conductivity, strength, etc.
• Quality Control: Ensure that each batch of products meets industry standards and customer requirements.

8. Packaging and delivery

• Package: Use appropriate packaging materials to prevent damage during transportation.
• Shipping：Arrange shipment according to orders to ensure that products are delivered to customers in a timely manner.

The above process ensures the high quality and performance of the cable copper tape to meet the needs of various applications.
