The enamelling process on vertical ovens consists in the application of an electro-insulating enamel film on a copper or aluminium wire. This system is exclusively used for the production of medium, big and flat wire (0,50 - 5,00 mm for round fine wire up to 100 mm2). The process phases are: 1) Bare wire annealing.

Copper production begins with acquiring raw materials like ore, concentrate, or matte. These raw materials come from mines around the world where ores containing copper sulfide minerals are extracted using open-pit mining or underground mining techniques. The ore is then crushed … See more

Step 1: Wire drawing. In the first step, our aim is to acquire metal (usually copper or aluminum) wires that fit with AWG (American Wire Gauge). The method is to pull the copper or aluminum rod through a series of synthetic diamond dies, which gradually decrease in size, on the draw bench. And this is processing with a lubricating and cooling ...

The first step in the process of cable manufacturing is wire drawing. Copper rods received from the supplier are too thick for usage in flexible wires so they will have to be stripped down to the required diameter. To …

This process is called Annealing. In this course, we pass an electrical current through the wire for a second at a temperature of 1000oFv. This is a very precise and controlled operation. Annealing is performed using water and in the process, it is made sure that no oxidation takes place or otherwise it could overheat and burn the coil.

3 Automated System for a copper wire manufacturing process using up-casting method In building systems such as this one, where expert knowledge in several areas is required, it is wise to implement mechatronic approach to design. Concise description of the mechatronics is given in [12] whereas in [11] it is presented in more detail.
