Question 4 (1 mark) Sumitomo Cable manufactures various types of aluminum and copper cables which it sells directly to retail outlets through its distribution channels. The manufacturing process for producing cables includes a process called wire draw in which the aluminum and copper rods are pulled through a series of synthetic dies, which gradually decrease in size. The wires are then passed through an extruder, where either a single or a double coating of plastic is applied. These insulated wires are twisted into pairs by the Twisting and Stranding Department. The final shape is given to the wires by the Jacketing and Packaging department after carrying out the process of quality control.
