Drawing process For copper wires an 8 mm copper rod (5/16″ in USA) is used as raw material, which is drawn through drawing dies to the required bare wire dimension in several stages. The copper rod has to be…
magnet wire manufacturing process
Electromagnetic wire or enameled wire, also known as winding wire, is a type of copper (Cu) or aluminum (Al) wire coated with a very thin insulating layer. It is used in the manufacture of transformers, inductors, motors, generators, speakers, hard…
Spools of Lacquered Wire
Lacquered wire (magnetic wire) is one of the main types of winding wire. It is composed of conductor and insulating layer. The bare wire is softened by annealing, then painted for many times and baked. Enameled wire spool is important…
Welding machine
There are many types of welding machines, including single-point single-function, single-point dual-function, single-point multi-function (this type of welding machine also has only one welding head, after changing the form of the positioning plate, it can be used for any angle…
Enameled wire production process: take-up
The purpose of winding and arranging the wire is to wind the enameled wire on the spool continuously, tightly and evenly. It is required that the wire take-up mechanism has a smooth transmission, low noise, proper tension and regular wire…
Enameled wire production process: pay off
.Simple and not enough attention, with the increase of enameled wire line speed, labor productivity. The growth of the pay-off part has also attracted people’s attention, in a normal operation On the enameling machine, most of the operator’s energy and…
Bare wire annealing
Annealing is a process at high temperature which aim to soften the copper and make it more malleable. The purpose of annealing is to make the conductor hardened by the lattice change during the mold stretching process to be heated…
Physical Varinishing process of enameled wire
Varinishing process is the process of applying enameled wire paint to metal conductors to form a uniform paint layer with a certain thickness. 1) Viscosity When the liquid flows, the molecules collide with each other to make one layer of…
Felt Varinishing process of enameled wire
The Felt Varinishing method has a simple structure and is easy to operate. As long as the felt splint is used to flatly clamp the felt on both sides of the wire, the felt is loose, soft, elastic and porous…
Varinishing times of enameled wire
The number of varinishing times is affected by the solid content, viscosity, surface tension, contact angle, drying speed, coating method, and paint thickness of the paint liquid. Generally, enameled wire enamel needs to be painted and baked several times to…
