The manufacturing process of tungsten wire for textiles weaving gloves usually includes the following steps:
Preparation of tungsten powder: First, tungsten powder is prepared by reducing tungstates (such as ammonium paratungstate, APT). The process usually uses hydrogen as a reducing agent at high temperature.
Pressing: The tungsten powder is pressed and formed into a dense tungsten rod. These tungsten rods are usually pressed by an isostatic press to ensure the uniformity and density of the rods.
Sintering: The tungsten rods are sintered at high temperatures to further increase the density and eliminate porosity. The sintering process is usually carried out in a vacuum or inert gas environment to prevent oxidation.
Forging and Drawing: The sintered tungsten rods are forged to increase their strength and toughness. Subsequently, the tungsten rods are heated and gradually stretched into tungsten wires of the required diameter through multiple drawing processes. After each drawing, the tungsten wires are annealed to eliminate internal stress and improve their flexibility.
Finishing and Cleaning: The drawn tungsten wires are cleaned to remove any lubricants that may remain on the surface. Tungsten wires are usually pickled or electropolished to ensure surface finish and quality.
Winding and Packaging: Finally, the finished tungsten wires are wound into coils and packaged and shipped according to customer requirements.
The production process of tungsten wire is very strict to ensure that it has excellent mechanical properties, high temperature resistance and chemical stability, which makes it very suitable for braiding applications.
