Lubricants for drawing enamelled wires

Enamelled wire is made up of a solid metal wire covered in an insulating resin called enamel.

For good-quality enamelling, the support wire must have a surface free from all faults: irregularities, residues and oxidation.

There are numerous applications for enamelled wires. The most important are:

• electric motor windings
• electromagnetic windings
• self-inductor windings for electronic equipment

The smallest diameters in the enamelled wire industry can be a few tens of microns. The wire can become very fragile and requires an effective lubricant to avoid breakage due to excessive traction.

Micro-emulsions and solution-based lubricants are especially adapted to the lubrication of these wires. They combine:

• performance
• cleanliness for optimum wire quality
