The production of tungsten skeins usually involves several steps:

Tungsten wire selection: Use high-purity tungsten wire as raw material. The wire was selected for its exceptional strength, high melting point and corrosion resistance, making it suitable for use in high temperature applications. Wire annealing: The selected tungsten wire has been annealed to improve its ductility and facilitate the subsequent twisting process. Annealing is heating the wire to a high temperature and then cooling it slowly, which helps remove internal stress and makes the wire more ductile. Twisting process: The annealed tungsten wire is then twisted to form the filament structure. The twisting process is carefully controlled to ensure the required filament dimensions and mechanical properties are achieved. Heat treatment: The twisted tungsten wire is subjected to a heat treatment process to further improve its mechanical properties such as strength and ductility. This step may involve heating the filament to a specific temperature and then cooling it under controlled conditions to obtain the desired metallographic structure. Quality Control and Testing: Throughout the entire production process, quality control measures are implemented to ensure that the tungsten wire meets the required specifications. This may involve testing the filament’s mechanical strength, dimensional accuracy and other key properties. Final processing: Once tungsten strands pass quality control inspections, they may undergo additional processing steps, such as surface treatment or coating application, to enhance their performance in specific applications.

The production of tungsten stranded wire requires precision manufacturing techniques and careful control of material properties to ensure that the resulting wire meets the high temperature requirements and mechanical properties required in applications such as semiconductor manufacturing.
