How Tungsten Stranded Wire is Produced？

Tungsten wire is a kind of consumable material for vacuum coating, which is generally composed of single or multiple doped tungsten wires in various shapes of metal products. Through a special heat treatment process, it has strong corrosion resistance and high temperature performance, good stability and long service life. It is currently widely used in vacuum coating of thin film technology, metal evaporation, mirror industry, aluminum and other decorative items, chrome plating, etc. Mirrors, plastic products, heating elements, picture tube industry and lighting industry and other fields.

??Let's take a look at the production process of tungsten stranded wire:

??Production process of tungsten stranded wire

1. Drawing

?Use a wire drawing machine and repeatedly draw the tungsten round rod to the appropriate size, such as Φ1.0mm,Φ0.85mm，Φ0.75mm,Φ0.6mm

2. Alkaline cleaning or electropolishing

?The tungsten wire after alkali washing is whitish, and the tungsten wire after electropolishing has metallic luster

3. Joint stock

Twist the tungsten wire into 2 strands, 3 strands, 4 strands or more with a plying machine, and the tungsten strands are ready for use.

4. Molding

?Use tungsten strand forming machine to process tungsten wire into various shapes of tungsten strand

5. Inspection and warehousing
