Magnet wire also called enameled wire is a copper or aluminum wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire.
In some cases, the insulation covered around the magnet wire need to be removed, and a kind of patented novel laser process that is able to remove the various coatings on enameled wires, MWS (Magnet Wire Stripping), has been developed, and it is the method of removing insulation coatings from the majority of magnet wire types with the cleanest, highest quality and most repeatable effect for now.
This enameled wire stripping technology is already used in the automotive industry, having been integrated into high volume production lines used in the manufacture of magnetic coil windings for alternators and starter motor stators.

MWS is Different from the Traditional Laser Stripping Process
The laser energy of this novel laser process is not directly absorbed by the insulation but rapidly heats the conductor surface, so a high-temperature plasma is formed at the interface between the conductor and the enamel insulation.
Breakage of the bond between the enamel and the conductor is turning up, then the enamel coating is blasted away from the conductor metal at high speed and disintegrates into small pieces. The application of an air blade and/or exhaust system make it possible that these small pieces can be removed from the process area for subsequent disposal.

Magnet Wire Stripping Advantages
1. The MWS technology is unlike thermal methods for enameled wire insulation removal, it leaves no remaining layer of insulation that can influence following processing, and there is no mess and no consumable parts as would be the case when using chemical or wire brush methods.
2. There is a further key benefit of MWS laser process. This process is also able to strip any oxide layer from the underlying conductor simultaneously, leaving the conductor in the ideal condition for subsequent electrical bonding by soldering, welding or other processes.
3. This laser process offers substantial operation and productivity benefits over alternative mechanical, chemical and hot wire thermal techniques. It can finish precise control of the laser strip location, size and depth, minimizing the possibility of end product defects, which results in higher yield, lower cost and increased product reliability.
