China wholesale Round Enameled Winding Wire - 0.011mm -0.025mm UEW Ultra-fine Enameled Copper Wire – Ruiyuan

The selection of copper wire as raw materials and the process of drawing play a key role in fine wire drawing. With the 0.80mm copper wire drawn to 0.011mm, it has to go through several procedures such as middle draw and annealing, small draw and anealing, fine draw and micro drawing with annealing,  In order to ensure the softness of wire, copper wire needs to be annealed every time when its cross section is compressed by 90%. Copper wire after drawing must keep bright, oxidation, discoloration and enamel stains must be avoided. Besides, the copper wire needs to be winded orderly and tightly on the take-up spool. We made a breakthrough in drawing 0.011mm fine enameled wire, and now we decidedly set our goal for 0.010mm.

Regarding painting. First the drawn thin copper wire is cleaned of some impurities on the copper wire through felt to ensure quality of enameled wire during painting. Cleaned enameled wire is put into enamel tank. The wire passes through the paint rolling machine that keeps it fixed in the machine. As the rolling machine rotates with the enameled copper wire, the wire will not waggle up and down so that the paint is even and insufficient painting won’t happen. Hence good quality of painting is guaranteed.
