Four characteristics of enameled wire
The enameled wire
consists of three parts:
2. Insulation layer (PU polyurethane)
3. Self-melting layer (PA polyurethane)
Use of enameled wire
Inductor coil, electromagnetic coil, AC and DC motor, automotive industry.
General production process:
Base metal - wire drawing - semi-finished products - annealing - painting - baking - finished products – packaging
include:enameled copper magnet wire
,enameled aluminum magnet wire
,copper clad aluminum winding wire
.it has four main characteristics: mechanical properties, chemical properties, electrical properties and thermal properties. Baking is a key process in the production of enameled wire. After the wire is painted, it enters the oven, and physical and chemical changes occur in the oven to evaporate the solvent in the paint solution and finally form a paint film. The process factors that play a major role in the production of enameled wire are the painting pass, the viscosity of the paint, the temperature distribution of the furnace and the line speed. These elements have stricter requirements on the thickness of the paint film depending on the type of paint liquid and the specifications of the wire.
China has become the world's largest production base for enameled wire, with production accounting for about 30% of the world's total production. In the past 20 years, China's enameled wire production has increased by more than 10% per year, reaching a scale of several million tons per year.
