Enameled wire coating type<\/p>\n

Polyurethane<\/p>\n

It is a clear varnish that is easy to directly contact by welding, fusion or crimping. Especially for small enameled wires, easy welding is the biggest advantage of this enameled wire.<\/p>\n

Polyesterimide<\/p>\n

More resistant to higher temperatures.<\/p>\n

Polyamide-imide and polyimide<\/p>\n

Offers highest temperature and chemical resistance.<\/p>\n

Painting process of enameled wire<\/p>\n

All enameled wires are enameled on special enameling machines. The enameling of enameled wires is a continuous process, which mainly includes annealing process, painting, curing process, lubricant application, tension control and reeling.<\/p>\n

1. Annealing process<\/p>\n

During the wire drawing process, the grain structure of the bare wire has been changed by cold deformation. Annealing will recrystallize the copper and make it soft again. This thermal stress relief process is carried out under a protective atmosphere to avoid oxidation of the wire surface, which would impair good adhesion of the subsequent initial insulation coating. The softness of the enameled wire is an important criterion for good windability and, in particular, to significantly reduce the number of wire breaks.<\/p>\n

2. Application of enameled wire<\/p>\n

There are 2 main application systems for winding enameled wire, namely felt application and die application, while felt application is mainly used for thin enameled wire production, while die application is mainly used for heavy enameled wire production. The coating of enameled wire should try to use a single layer instead of fewer and thicker coatings to achieve better mechanical and electrical properties of the enameled wire.<\/p>\n

3. Curing oven<\/p>\n

The solvent contained in the enamel liquid is driven out by the high temperature in the curing oven and then catalytically burned using the heat energy in an environmentally friendly way. Temperature control is very important: if the temperature is too low, too much solvent remains in the enamel layer, resulting in poor adhesion and reduced mechanical and electrical properties of the enameled wire. If the temperature is too high, the enameled layer will become hard and brittle, causing cracks in the insulation layer of the enameled wire due to mechanical stress.<\/p>\n

4. Lubrication<\/p>\n

A precise amount of lubricant is applied to the surface of the insulating enameled wire. Lubrication is necessary to achieve stable winding performance and trouble-free winding, even at high winding speeds.<\/p>\n

5. Diameter control<\/p>\n

The outer diameter of all enameled wires is continuously monitored by laser after the last process step.<\/p>\n

6. Tension control<\/p>\n

During the enameling process, continuous wire tension control keeps the wire diameter on the spool consistent. Through effective tension control, the enameled wire can be avoided from being stretched and thus from changing its resistance. In addition, the enameled wire provided to customers can be guaranteed to have good wire withdrawal properties.<\/p>\n

7. Spool<\/p>\n

The wire spacing and the spool rotation speed are variables in the spooling process that need to be tightly controlled. This ensures consistently good pay-off properties of the magnet wire and minimizes other problems such as wire jamming and tangling.<\/p>\n

8. Monitor<\/p>\n

The monitor informs the operator of all important process parameters.<\/p>","protected":false},"excerpt":{"rendered":"
