Product Details

Self bonding enamelled copper wire refers to a wire with self-adhesive properties formed by coating the outer layer of insulating paint film with a layer of self-adhesive paint. Compared with ordinary enameled copper wire, self bonding wire not only has its own wire diameter specification It is small and does not need to use auxiliary materials such as skeleton during the winding process, which can greatly reduce the weight and volume of the winding, and is more suitable for micro and small electronic components and electronic products

1. Conductor Material

Copper:

We use copper from peru to manufacture oxygen-free copper. Only high-quality raw materials can ensure the performance of self bonding enamelled copper wire. The copper rod manufacturing equipment of the South Line helps us to produce efficiently. Coupled with China's perfect industrial chain, raw materials are continuously shipped to the factory.

5. Self bonding Film

Alcohol self bonding: The self-bonding effect is achieved by adding an appropriate solvent (such as industrial alcohol) to the wire during the winding process. The recommended solvent is ethanol or methanol.

Hot air self bonding: Hot air is to achieve self bonding effect by blowing hot air on the wire during the winding process. The temperature of the hot air at the winding is usually between 120ºC-230ºC

Oven self bonding: Oven self bonding is achieved by placing the finished coil in an oven to heat it to achieve self adhesive effect. In order to achieve uniform heating of the coil, according to the shape and size of the coil, the temperature of the oven usually needs to be between 120 ° C and 220 ° C, and the required time varies from 5 to 30 minutes.

Power on self bonding: Electric self bonding is achieved by electric current (resistive heating). The required amperage depends on the shape and size of the coil. Power on self bonding is recommended for products with wire diameter above 0.10mm (38AWG)
