What you need to know about Micro-Coil Winding


There are many applications for coil winding, especially in the medical field. It has become very important to learn and understand what is coil winding. The first thing to learn is that the winding process requires unique and highly specialized machinery. Coupled with engineers with technical know-how to ensure that the quality of the products produced meet the high standards set in place. What differentiates micro coil winding from other winding processes is the size of the wires wound. Micro coil winding involves the winding of wires that are very thin with a diameter of 0.8mm. Such wires are used in the medical field and are inserted into veins requiring them to be very thin.

The micro wires used in winding require insulation before the winding procedure begins. It’s crucial to ensure that the wires used in the winding process do not come into contact with each other.There are many materials used in the coil winding process. Most of these materials do not require insulation since there are resistant to breakdown from electric current flowing through the wires. However, whenever the manufacturers use copper, they have to ensure that they insulate it since it is not resistant to breakdown. They wind the micro wires around the pin or core. During the winding process, the micro coils produce a field of an electromagnet through the process of electromagnetic induction. There are several shapes that they shape the micro coils into through the winding process:

  • Circular
  • Rectangular
  • Elliptical

The different shapes produce by the winding process have an impact on the electrical properties of the coils. The shape the coil is wound into can enhance the induction process.

What is required for coil winding?

  • Custom-built State of the art specialized equipment.
  • Highly qualified engineers who have experience in the field designing machinery used in the manufacture of micro coils. Since the machinery used in the coil winding industry is custom built and is not available in the market.
  • Technical know-how in dealing with miniature devices that make use of the micro coils produce during the coil winding process. It’s crucial to understand the different methods used when handling wires that are wound down to a diameter of 0.00035 inches or about 9 microns.
  • Dealing with these wires requires staff that is experienced and is very careful since most of these wires are wound to sizes that are thinner than a human hair.
